So I am attempting to add a repeated field to protobuff. However, whenever I generate the file using make, add_linkage does not take any arguements as if it's not actually able to read in the type that linkage is suppose to take (it's another protobuffer.) What am I doing wrong in the protobuffer file?
package model_velocity.msgs;
import "vector3d.proto";
message ModelVelResponse
{
required string name = 1;
required gazebo.msgs.Vector3d angularVel = 2;
required gazebo.msgs.Vector3d linearVel = 3;
}
message ModelVel_V{
repeated ModelVelResponse linkage = 1;
}
Do I need to do something different? Do I need to call a different function to repeat the message? Any help would be appreciated.
add_linkage() doesn't take any arguments. repeated message types' add_x() method return a pointer to a new, empty instance of the message. You need to do something like ModelVelResponse* resp = my_vodel_vel_v.add_linkage();. Then you can assign to the fields of the returned message as needed.

I want to get the email body from my Gmail account for an email so i use this code i found it in an example for how to read emails using c++ builder pop3
the code to extract body used
TIdText *EText;
int message = SpinEdit1->Value;
MyPoP3->Retrieve(message, MyEmail);
Edit1->Text = MyEmail->Subject + " | " + MyEmail->From->Address;
Memo1->Clear();
for (int i = 0; i < MyEmail->MessageParts->Count; i++) {
Memo1->Lines->Add(MyEmail->MessageParts->Items[i]->ContentType);
EText = dynamic_cast<TIdText*>(MyEmail->MessageParts->Items[i]);
Memo1->Lines->Add(EText->Body);
}
the problem is that i got undefine symbol to TidText and what i tried is to change it from TIdText to TIdMessage, but i got that i can't convert to it.
also i tried to try this without loop or something MyEmail->Body->Text
this return empty string.
the video i got this code from it here i don't know maybe the c++ builder he use is old. now i want to know how to extract the body text from the email address.
Thanks in advance.
the problem is that i got undefine symbol to TidText
Your code is missing an #include <IdText.hpp> statement.
what i tried is to change it from TIdText to TIdMessage, but i got that i can't convert to it.
Because TIdMessage does not contain nested TIdMessage objects.
also i tried to try this without loop or something MyEmail->Body->Text this return empty string.
If your email is MIME encoded, its text is not stored in the TIdMessage::Body property, but in a nested TIdText object within the TIdMessage::MessageParts collection. You have to look at the TIdMessage::ContentType property to know what kind of structure the email contains. For instance, if the CT begins with text/, the text is in the TIdMessage::Body. But if the CT begins with multipart/, the text is somewhere in the TIdMessage::MessageParts instead.
You should read this blog article on Indy's website for an example of how emails might be structured:
HTML Messages

No, it is not.
This code I have written for creating large dropdown in ColdFusion, but it is not working on my end. Could any one please help me rectify my problem. The new code is
<cfquery name="getPOP" datasource="l_webalc">
select distinct center_code from alc_pop
</cfquery>
<cfset countryName= ArrayNew(1)>
<cfloop query="getPOP">
<cfset arrayappend(countryName, getPOP.center_code)>
</cfloop>
<script>
workbook = new HSSFWorkbook();
realSheet = workbook.createSheet("Sheet xls");
hidden = workbook.createSheet("hidden");
for (int i = 0, length= countryName.length; i < length; i++) {
String name = countryName[i];
HSSFRow row = hidden.createRow(i);
HSSFCell cell = row.createCell(0);
cell.setCellValue(name);
}
namedCell = workbook.createName();
namedCell.setNameName("hidden");
namedCell.setRefersToFormula("hidden!A1:A" + countryName.length);
constraint = DVConstraint.createFormulaListConstraint("hidden");
addressList = new CellRangeAddressList(0, 0, 0, 0);
validation = new HSSFDataValidation(addressList, constraint);
workbook.setSheetHidden(1, true);
realSheet.addValidationData(validation);
stream = new FileOutputStream("c:\\range.xls");
workbook.write(stream);
stream.close();
</script>
Update 1:
(From other thread) I am getting this error message:
function keyword is missing in FUNCTION declaration. The CFML compiler
was processing: A script statement beginning with HSSFWorkbook on line
32, column 1. A script statement beginning with function on line 31,
column 9. A cfscript tag beginning on line 30, column 2.
Update 2:
Again I have modified this code and now the new error is
"The value hidden not A1:A cannot be converted to a number."
I edited the objects as mentioned in the comments and also changed the script to cfscript. Please help me to rectify this error.
<cfscript>
workbook = createObject("java", "org.apache.poi.hssf.usermodel.HSSFWorkbook");
realSheet = workbook.createSheet("Sheet xls");
hidden = workbook.createSheet("hidden");
for (i = 1; i <= arrayLen(countryName); i++){
name = countryName[i];
row = hidden.createRow(i);
cell = row.createCell(0);
cell.setCellValue(name);
}
namedCell = workbook.createName();
namedCell.setNameName("hidden");
namedCell.setRefersToFormula("hidden!A1:A"+arrayLen(countryName));
dv = createObject("java", "org.apache.poi.hssf.usermodel.DVConstraint");
constraint = dv.createFormulaListConstraint("hidden");
addressList = cellRangeList.init(0, 0, 0, 0);
validation = dataValidation.init(addressList, constraint);
workbook.setSheetHidden(1, true);
realSheet.addValidationData(validation);
stream = new FileOutputStream("c:\\range.xls");
workbook.write(stream);
stream.close();
</cfscript>
Update 3:
I have updated the code to fix the mentioned issues and and am now getting this error
"The setSheetHidden method was not found ..."
on the following line:
workbook.setSheetHidden(1, true);
There are several problems with your code. Though java syntax is similar, you cannot just copy and paste a java example and expect it to run in cfscript. You need to make some adjustments first. (Note: I am assuming script was just a typo for cfscript).
In java, you can instantiate an object using the keyword "new" ie new SomeClassName(). In CF, the new keyword can only be used with cfc's. To create a java object, you must use createObject instead. To instantiate it, call the init(...) method. It is a special method in CF that invoke's the constructor of a java class with whatever parameters you supply, ie
createObject("java", "path.to.SomeClassName").init();
To use static methods such as DVConstraint.createFormulaListConstraint(), you must also use createObject. While the java code does not create an new instance of that class, you must still use createObject to get a reference to the DVConstraint class, in CF, before you can invoke any of its methods. Note: Because it is static, no need to call init() first. ie
dv = createObject("java", "org.apache.poi.hssf.usermodel.DVConstraint");
dv.createFormulaListConstraint(...);
Java classes are organized into packages. In java classes, the full path to any referenced classes are imported at the top of the java code (not visible in the example you are using). In CF you need to use the full path in your createObject call. (Important: Paths are cAsE sEnsItIvE).
For example, instead of new HSSFWorkbook() use:
createObject("java", "org.apache.poi.hssf.usermodel.HSSFWorkbook");
If you are not sure of the path, just do a search on "POI TheClassName". Odds are the first result will be the POI JavaDocs, which show the full path at the top of each page like this:
java.lang.Object
|---org.apache.poi.ss.util.CellRangeAddressList
Unlike CF, java is strongly typed, which means you must declare a variable's type as well as it's name. For example, this line declares a variable row as type HSSFRow
HSSFRow row = hidden.createRow(i);
Since CF is typeless, it does not require a type. So running that same code in cfscript will cause the cryptic error "function keyword is missing...". The solution is to drop the variable type and just do a straight variable assignment:
row = hidden.createRow(i);
Java array indexes start at zero (0), while CF starts at one (1), so you need to fix the indexes in your for loop:
for (i = 1; i <= arrayLen(countryName); i++)
Java uses + to concatenate strings, whereas CF uses &. So you need to change the operator here "hidden!A1:A" + countryName.length. Otherwise CF will think you are trying to add two numbers, which will obviously throw an error because the first part is a string.
Assuming no version conflicts, the java example should work after you make those those adjustments.
"The setSheetHidden method was not found ..."
Just use Javacast function for boolean arguments:
workbook.setSheetHidden(1, javacast("boolean",true));
Is it somehow possible to add the sub-group of a cetrain group the address is assigned to the html output?
In the template I have ###MAINGROUP### and ###GROUPLIST###. I can't use maingroup, cause it's not the case that the group I need is always the maingroup. And with the grouplist I can't say which group is the sub-group of the one group.
Anyone have an idea how I could do it?
And in addition to that I also need the value of a self created field in the tt_address table.
Edit:
I try it like #lorenz say. What I have so far:
ext_localconf.php:
<?php
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['tt_address']['extraItemMarkerHook'][]
='EXT:txnextaddresssort/class.tx_next_address_sort_addmarkers.php:tx_next_address_sort_addmarkers';
class.tx_next_address_sort_addmarkers.php:
<?php
class tx_next_address_sort_addmarkers {
function extraItemMarkerProcessor(&$markerArray, &$address, &$lConf,
&$pObj) {
$lcObj = t3lib_div::makeInstance('tslib_cObj');
$lcObj->data = $address;
$markerArray['###SORTBEREICH###'] =
$lcObj->stdWrap($address['tx_nextaddresssort_sort_bereich'],
$lConf['tx_nextaddresssort_sort_bereich.']);
}
}
Extentionkey: next_address_sort
All I get is a blank screen, but no errors in apache log
No, there is no possibility to do that.
Yet you can write a custom extension that integrates the extraItemMarkerProcessorhook in tt_address. In ext_localconf.php, add:
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['tt_address']['extraItemMarkerHook'][] ='EXT:myextension/class.tx_myextension_filename.php:tx_myextension_classname';
Then add a file class.tx_myextension_filename.php to your extension.:
class tx_myextension_classname {
public function extraItemMarkerProcessor(&$markerArray, &$address, &$lConf, &$pObj) {
$lcObj = t3lib_div::makeInstance('tslib_cObj');
$lcObj->data = $address;
$markerArray['###MYFIELD###'] = $lcObj->stdWrap($address['myfieldlikeindatabase'], $lConf['myfieldlikeindatabase.']);
return $markerArray;
}
}
This would be an example for getting a field that is in the tt_address table and adding it to the markers so they can be used in a template. It is also stdWrap enabled.
Now, instead of getting a field, you should replace $address['myfieldlikeindatabase'] with a variable that contains the information you need. To receive the data, you can use the TYPO3 database API functions ($GLOBALS['TYPO3_DB']).
I want to place some helper functions in another file, since they will be overly reused. I took the Computer-Databse sample's listing file:
https://github.com/playframework/Play20/blob/master/samples/scala/computer-database/app/views/list.scala.html
I created a new file, called "listing.scala.html" under the app/views package, and moved the #link function from the original file to it. This new file looks like this:
#(currentSortBy: String, currentOrder: String, currentFilter: String)
#****************************************
* Helper generating navigation links *
****************************************#
#link(newPage:Int, newSortBy:String) = #{
var sortBy = currentSortBy
var order = currentOrder
if(newSortBy != null) {
sortBy = newSortBy
if(currentSortBy == newSortBy) {
if(currentOrder == "asc") {
order = "desc"
} else {
order = "asc"
}
} else {
order = "asc"
}
}
// Generate the link
routes.Application.listPerfil(newPage, sortBy, order, currentFilter)
}
So, on my original file, I replaced the #link call, with this one:
#title
And the problem is, when I try to compile I get this error:
value link is not a member of play.api.templates.Html
But according to the documentation (http://www.playframework.org/documentation/2.0.4/ScalaTemplateUseCases) it seems to be ok.
Any guess?
Play's templates aren't the best place for placing advanced conditions, most probably you'll get better flexibility by processing it in some controller (or other method) which will return you only required link
ie.:
#title
In your case proposed link(...) function of Application controller can also return a reverse-route.
Keep in mind that including other templates is best option for repeating blocks of HTML but sometimes it's hard to get specified string (mainly because of not trimmed spaces). As you can see there is also problem with calling nested functions. Most probably you can generate whole A tag in the listing.scala.html however using it isn't comfortable enough (IMHO).
I am trying to work out the correct <cfscript> syntax for calling a dynamic method within ColdFusion 9. I have tried a number of variations and had a good search around.
<cfinvoke> is clearly the tag I want, sadly however I cannot use this within my pure cfscript component as it was implemented in ColdFusion 10.
i.e coldfusion 9 dynamically call method
I have tried the following within my CFC:
/** Validate the method name **/
var resources = getResources();
if (structKeyExists(variables.resources, name)) {
variables.resourceActive[name] = true;
var reflectionMethod = resources[name];
var result = "#reflectionMethod.getMethodName()#"(argumentCollection = params);
}
Where the return value of reflectionMethod.getMethodName() is the method name I want to call. It is 100% returning the correct value (the name of the method) where that method is correctly defined and accessible,
My error is a syntax error on that line.
You don't want to get the method name, you want to get the actual method, eg something like:
function getMethod(string method){
return variables[method];
}
The call that, thus:
theMethod = getMethod(variableHoldingMethodName);
result = theMethod();
Unfortunately one cannot simply do this:
result = getMethod(variableFoldingMethodName)();
Or:
result = myObject[variableFoldingMethodName]();
As the CF parser doesn't like the double-up of the parentheses or brackets.
The caveat with the method I suggested is that it pulls the method out of the CFC, so it will be running in the context of the calling code, not the CFC instance. Depending on the code in the method, this might or might not matter.
Another alternative is to inject a statically-named method INTO the object, eg:
dynamicName = "foo"; // for example
myObject.staticName = myObject[dynamicName];
result = myObject.staticName(); // is actually calling foo();
Assuming the method is in your current (variables) scope, you could try:
var result = variables[reflectionMethod.getMethodName()](argumentCollection = params);
