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

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).

Is this other project a library? If so, you need to include the header and add that lib to your project.

maybe you need to import library(lib) in your program

hiiiiiiiiiii,
this is the solution...
u have to do is:
1) u need to Dervie a class from CListBox
2) map the listbox in ur application to Derived listbox class.
3)Override the virtual function OnChar in ur Derived class.
void CMyListBox::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// TODO: Add your message handler code here and/or call default
//CListBox::OnChar(nChar, nRepCnt, nFlags); important
}
comment this code
CListBox::OnChar(nChar, nRepCnt, nFlags);
Regards

Try this way. Using Add Class command, add a new MFC class derived from CListBox. Then add to this class a handler for WM_CHAR notifications. In this handler, return without calling anything.
In the dialog box where list box is used, select the list-box and then use Add Variable in order to add a control variable. In the Variable Type field, specify the name of your list-box class.
If you already have a variable for your list, then open the header file of your dialog and replace CListBox type with the name of your list-box class.
Hope it helps.

I've written an application which will use virtual COM port (USB-to-Serial) to communicate with my device. I am using CreateFile/ReadFile/WriteFile functions. It is running fine until one issue found.
With the application open, when (somehow) the USB driver reload, my application fail to perform read/write. Even after I close the application and reopen it, it fails to get the handle.
Why is it happen? Are there anything that my application need to do when the USB driver is re-loaded?
Thanks.
