I want to check if the Text box has some text entered by the user but can't. The statement below always returns false
if (MyLLVTextEdit->getMessage() == NULL)
{
MessageBox(NULL,"No Text", "no Text",NULL);
}
also tried
if (MyLLVTextEdit->getMessage() == "")
{
MessageBox(NULL,"No Text", "no Text",NULL);
}
if (MyLLVTextEdit->getValue() == NULL)
{
MessageBox(NULL,"No Text", "no Text",NULL);
}
if (MyLLVTextEdit->getValue() == "")
{
MessageBox(NULL,"No Text", "no Text",NULL);
}
Any ideas please?
Don't familiar with your library, but you should use strcmp function to compare strings (char*), to check if string is empty, you may call strlen
strlen(MyLLVTextEdit->getMessage()) == 0
operator== may be used only if you use some string classes like std::string QString or whatever
What does getMessage() return? Very unlikely char*, as Rogue Wave has own unicode-capable string classes.
If it a kind of a Rogue Wave string-class, check if there is a method for testing the content for emptiness.
Probably you should use something like:
if (MyLLVTextEdit->getMessage().isNull() )
or
if (MyLLVTextEdit->getMessage().isEmpty() )

I have tried to look up the "identifier not found" error only to find posts where the function must be moved outside the main loop or should use a forward declaration. However, my script is used as a module for a game engine thus has no real main loop and the function in question is called by a different function above the failing line with no issues:
// Create a Steam ID
CSteamID Steam::createSteamID(uint32 steamID, int accountType){
CSteamID cSteamID;
if(accountType < 0 || accountType >= k_EAccountTypeMax){
accountType = 1;
}
cSteamID.Set(steamID, EUniverse(k_EUniversePublic), EAccountType(accountType));
return cSteamID;
}
// Set a Steam user as someone recently played with
void Steam::setPlayedWith(int steamID){
if(SteamFriends() == NULL){
return;
}
CSteamID friendID = createSteamID(steamID);
SteamFriends()->SetPlayedWith(friendID);
}
// Get friend's Steam username
String getFriendPersonaName(int steamID){
if(SteamFriends() == NULL || steamID == 0){
return "";
}
CSteamID friendID = createSteamID(steamID);
bool isDataLoading = SteamFriends()->RequestUserInformation(friendID, true);
if(!isDataLoading){
return SteamFriends()->GetFriendPersonaName(friendID);
}
}
The ID creation function sits at the very top and these two functions come much later. The first one (setPlayedWith) succeeds no problem but the second one (getFriendPersonaName) fails with: 'createSteamID': identifier not found when compiling the script.
I'm kind of at a loss and hopefully someone can point me in the right direction.
if getFriendPersonaName() is a member function then you have forgotten to define it the correct way so it will look like:
string Steam::getFriendPersonaName(int steamID)...
if it is not a member then you can't access it. however you can Only access it if getFriendPersonaName() is a friend function where you should edit the signature to:
String getFriendPersonaName(int steamID, const steam& rhs);
TCHAR* pszBackupPath;
m_Edt_ExportPath.GetWindowText(pszBackupPath, dwcchBackupPath);
StrTrim(pszBackupPath, L" ");
StrTrim(pszBackupPath, L"\\"); //this line has issue
iRet = _tcslen(pszBackupPath);
boRet = PathIsNetworkPath(pszBackupPath);
if (FALSE == boRet)
{
// MessageBox with string "Entered path is network path.
}
boRet = PathIsDirectory(pszBackupPath);
if (FALSE == boRet)
{
// MessageBox with string "Entered path is not a valid directory.
}
This is a part of my code in MFC.
I am passing a network path from UI. But because of StrTrim(pszBackupPath, L"\\") "\\" get trimmed from start and end. But I want it to be trimmed from end only.
I don't know any direct API. Please suggest.
There is a simple function to do that: PathRemoveBackslash (or PathCchRemoveBackslash for Windows 8 and later).
I have a textbox which should only accept Characters:-for that first regex has been set in constraint and it should not accept some reserved keywords that are A,R,F,U .Since two different constraints are set ,i want user to see the specific message ,for first it should be Illegal Value i.e default zkoss error and when he/she enters a reserved character ,it should show that reserved code has been put.
But somehow the following code doesnt work :
field_code.setConstraint("/[a-zA-Z]/ : {Illegal Value} ,/[^AaRrUuFf]/ : Reserved Code");
The output is the first regex works fine but on offending the same " {Illegal Value} ,/[^AaRrUuFf]/ : Reserved Code" is displayed as error.
You can't do it in the zul, but with help of a SimpleConstraint you could create this.
Create your own class, and extend SimpleConstraint.
Then hold 2 Matcher vars for each constraint.
At last, override the Validate method to something like this :
#Override
public void validate(Component comp, Object value) {
if (value != null && value instanceof String) {
String stringValue = (String) value;
if (!expression1.reset(stringValue).matches()) {
throw new WrongValueException(comp, errorMsg1);
}
if (!expression2.reset(stringValue).matches()) {
throw new WrongValueException(comp,errorMsg2);
}
} else {
// do what needs to be done when value is null or not a String.
}
}
I'm using pocketshpinx for speech recognition in a custom C++ application. I noticed that sometimes the hypothesis string returned by the ps_get_hyp() method is an empty string.
Question: Is this an expected behaviour? If so, is there a way to tell pocketsphinx to not give the empty string as a hypothesis?
Following is a snippet of the relevant portion of my code:
do { ReadAudioBuffer(); } while (!in_speech);
while (in_speech) { ReadAudioBuffer(); }
ps_end_utt(ps);
hyp = ps_get_hyp(ps, NULL);
The ReadAudioBuffer() method:
void SpeechRecognizer::ReadAudioBuffer()
{
if ((k = ad_read(ad, adbuf, 2048)) < 0)
{
UE_LOG(LogTemp, Warning, TEXT("Failed to read audio\n"));
return;
}
ps_process_raw(ps, adbuf, k, FALSE, FALSE);
in_speech = ps_get_in_speech(ps);
FPlatformProcess::Sleep(0.005);
}
Question: Is this an expected behaviour?
There is nothing wrong with it
If so, is there a way to tell pocketsphinx to not give the empty string as a hypothesis?
If you said nothing what should be returned then?
FPlatformProcess::Sleep(0.005);
Sleep is not really needed here
My TestNG test implementation throws an error despite the expected value matches with the actual value.
Here is the TestNG code:
#Test(dataProvider = "valid")
public void setUserValidTest(int userId, String firstName, String lastName){
User newUser = new User();
newUser.setLastName(lastName);
newUser.setUserId(userId);
newUser.setFirstName(firstName);
userDAO.setUser(newUser);
Assert.assertEquals(userDAO.getUser().get(0), newUser);
}
The error is:
java.lang.AssertionError: expected [UserId=10, FirstName=Sam, LastName=Baxt] but found [UserId=10, FirstName=Sam, LastName=Baxt]
What have I done wrong here?
The reason is simple. Testng uses the equals method of the object to check if they're equal. So the best way to achieve the result you're looking for is to override the equals method of the user method like this.
public class User {
private String lastName;
private String firstName;
private String userId;
// -- other methods here
#Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (!User.class.isAssignableFrom(obj.getClass())) {
return false;
}
final User other = (User) obj;
//If both lastnames are not equal return false
if ((this.lastName == null) ? (other.lastName != null) : !this.lastName.equals(other.lastName)) {
return false;
}
//If both lastnames are not equal return false
if ((this.firstName == null) ? (other.firstName != null) : !this.firstName.equals(other.firstName)) {
return false;
}
//If both lastnames are not equal return false
if ((this.userId == null) ? (other.userId != null) : !this.userId.equals(other.userId)) {
return false;
}
return true;
}
}
and it'll work like magic
It seems you are either comparing the wrong (first) object or equals is not correctly implemented as it returns false.
The shown values are just string representations. It doesn't actually mean that both objects have to be equal.
You should check if userDAO.getUser().get(0) actually returns the user you are setting before.
Posting the implementation of User and the userDAO type might help for further clarification.
NOTE: Note directly related to this question but it's answer to my issue that got me to this question. I am sure more ppl might end-up on this post looking for this solution.
This is not precisely the a solution if Equals method needs overriding but something that I very commonly find myself blocked due to:
If you have used Capture and are asserting equality over captured value, please be sure to get the captured value form captured instance.
eg:
Capture<Request> capturedRequest = new Capture<>();
this.testableObj.makeRequest(EasyMock.capture(capturedRequest))
Assert.assertEquals(capturedRequest.getValue(), expectedRequest);
V/S
Assert.assertEquals(capturedRequest, expectedRequest);
while the compiler wont complain in either case, the Assertion Obviously fails in 2nd case
