if your problem is in editbox do you have ES_WANTRETURN in property edit

My edit controls are single-line.
in fact, what I want is send a message to Parent window, when the focused edits/buttons get Enter/ESC key.

Try WM_GETDLGCODE

That's why PreTranslateMessage is not a very clean solution. Prefer the solution described in the FAQ[^]. In this way, you still have the complete flow of messages inaltered, it is just the closing of the dialog that is suppressed and you don't need to make tricks to get back your esc and enter messages when you need them.

then, how to handle the enter/esc key for Edit control and buttons?
And seems that it doesn't enter into the OnChar() at all.

Then your problem is elsewhere, it has nothing to do with the destruction of the dialog on enter or Esc.

yes
the code below <b>else </b> is where I need your kindly help.
if (!GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit)))
return true;// do nothing and ignore the key process
else
{
<u><b> ...............
//add proper code for EDIT control capture the Enter and ESC key.</b></u>
}

Why are you doing that in PreTranslateMessage ? I think you can simply add a message handler for WM_CHAR or WM_KEYDOWN for the edit control no ? I'm not sure about that, so you have to check.

I tried, and failed......
if there is no better methord,I would have to add the edit proc function in PreTranslateMessage() directly...

Your logic seems to be wrong. You want the condition to be true right?

By returning true from PreTranslateMessage(...), you are telling your application to bypass any default handling of the message.

GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit)) is for checking current focus on Edit control or not.
if it is not on edit control, will return and do nothing,if the focus is on edit control, then do what I want to....

yes, or it will close the dialog

If this return true it means the current focus is in an edit control (could be any edit control). If it return false, it mean focus is not in any edit control.

Then you code should be:
if (GetFocus()->IsKindOf(RUNTIME_CLASS(CEdit)))
{
}

I wonder why nobody suggested overriding the "onOk" and "onCancel" functions of the CDialog.  , that's the simplest way to get rid of your 'escape' and 'enter'.

I am using a drop down list CComboBoxEx and I am seeing a very strange behaviour(bug?).
When I left click on the ComboBoxEx, the list drops down. If I do not move the mouse and do not select any item in the list and then perform another left click, the list will close up and then drop down again.
If I right click or select an item and left click instead, the list will just close up correctly.
Does anyone knows how to solve this problem ?
PS. The ComboBox works fine, but Project need to use ComboBoxEx .

Is there someone that know how to solve this problem?
any answer will be greatly appreciated.

I created a test project to try out your problem here but i dont have that issue like you described. Does your control looks like losing focus and getting it back again in a split sec?

Thank you for taking time to test this.
This happens in VC6 SP6,WinXP and Win2k
I have found the same problem in
www.codeguru.com/forum/archive/index.php/t-354179.html
but there is no answer
Thank you in advance

See the following code
BOOL CmyApp::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_KEYDOWN && (VK_ESCAPE == pMsg->wParam || VK_RETURN == pMsg->wParam))
pMsg->wParam=NULL;
return CWinApp::PreTranslateMessage(pMsg);
}
Knock out 't' from can't,
You can if you think you can

Hi...
i got problem when compiling & linking my app in visualC++. I got the error msg like this:
------------------- the error msg -------------------
Linking...
Cobalagiah.obj : error LNK2001: unresolved external symbol "public: static int __cdecl ReadBitstreamFile::create(class ReadBitstreamFile * &)" (?create@ReadBitstreamFile@@SAHAAPAV1@@Z)
Debug/Cobalagiah.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Cobalagiah.exe - 2 error(s), 0 warning(s)
------------------- end of the error msg -------------------
the situation is as follow. there is one workspace with many projects in it. I have to make my own project in the same workspace and utilize some classes from other projects (within the same workspace).
So i set the directory paths to include the other header files (Tools - Options - Directories tab). by doing that i can put the code #include "ReadBitstreamFile.h" and compiling it was ok.
but then when I put this code in the main function (just for testing)
----------------- my testing code -----------------
int main(int argc, char* argv[])
{
ReadBitstreamFile *pcReadBitstreamFile;
ReadBitstreamFile::create( pcReadBitstreamFile );
printf("Hello World!\n");
return 0;
}
----------------- end of my testing code -----------------
that error occurs. note that the "create" function is a static function. it is defined in other class in other project.
anybody can help, please?
regards,
Hendry

You have also to add the cpp file in which ReadBitstreamFile is defined to your project. Do that simply by tight-clicking on the file views on the directory with the source files of your project. Then select add file (or something similar, depends of the IDE you are using).
