How do I always show the vertical scrollbar in an CListCtrl (report view)? Just call ShowScrollBar( SB_VERT, true ); in every OnSize method doesn't work, because then the last column (which has the flag LVSCW_AUTOSIZE_USEHEADER) is too big.
The implementation of the CListCtrl seems to be really clumsy, because it is somehow handled completely different than in any other WIN32-Control. Thanks for any answer.

Hi,
I'm trying to solve the very same problem and I haven't been successfull with that ShowScrollbar-function either.. It doesn't help that I'm not that experienced with MFC.
I'm wondering that could this be solved by simply using the WS_VSCROLL style when creating the control?
Well, in my app the scrollbar _does_ show in certain situations when using that style (even if there are only few items in the report view and therefore no actual need for the scrollbar) but I haven't been able to pinpoint the exact conditions for this. My guess is that this behavior has something to do with redrawing.. You tell me 
But hey, give it a try and let the world know if it works..

Your path to the lib-files seems to be invalid. Just set the correct path in Visual Studio. If you use version 2003 go to Tool->Options->Projects->Vc++ Directories and set the correct path for library files.
In Visual Studio 6 it should be very similar.

I have an edit box to be enabled when user tick check box and disabled when box is unchecked.
I want the disabling/enabling to be done immediately after user use the mouse click to check/uncheck. How do i detect the mouse click? currently the code is:
if(left mouse click and box is checked){
GetDlgItem( IDC_BUTTON1 )->EnableWindow(TRUE);}
else{
GetDlgItem( IDC_BUTTON1 )->EnableWindow(FALSE);
}
|
|

Handle the BTNCLICK massage for the check box.Note associate a boollean member variable with the checkbox tocheck the current status.

Hi All,
Win32 console based application
How to lock a Edit control such that it accepts only AlphaNumeric datas?
I tried to get WM_COMMAND and then EN_CHANGE, and remove the invalid data and placed it back in the Edit control by using Sendmessage and SetDlgItemText. But, the cursor moves to the begin of the Edit control?
How to move to the cursor back to the end of the text in the Edit Control??
Or else, is there is any other way to do that?
With Best Regards,

Re try catching WM_CHAR message, if not a valid result set nChar to 0;
Good Luck.
|
|
|
|
|
Hi,
What is nChar??
I am not able to catch the WM_CHAR message.
Control is not coming there. Instead it is going to WM_COMMAND.
How to do it?
With Thanks,

I have a wierd situation. I have a MFC based dialog application that loads dynamically an MFC dialog based dll.
If I build the application in release mode and try to load the debug mode dll the application crashes. Likewise if I build the application in debug mode and load the release mode dll the application crashes.
Any ideas why?

Hello!
Most probably (for sure) it is because of different memory allocators in release and debug version. Also, there might be problems with alignment (though I do not suspect that you have different alignment in debug and release).
Does it work in both debug and both release?
|
|
|
|
|
Yes, it works fine with either both in debug or both in release.
Both make use of threads if that could have anything to do with it.
What do you mean by different memory allocators?
I will have to look into this alignment issue. I changed several things in the process of
learning to get plug-ins working and everything else working as well.
Oh, I am using a GDI+ header helper file that I believe I found on codeproject that does some strange things to fix some memory issues.
Thanks,
Steve

Hello!
"What do you mean by different memory allocators?"
In debug build, memory allocator allocates for example guardians (additional bytes before and after allocated block of memory). Guardians are used to detect memory overwrites.
Generally, there are a lot of differences between allocating memory in release and debug version. See msdn for more details

Hi all,
I want to write a usb serial device driver for WinXP.
Would any expert here can give me some help?
e.g. source code, document, etc....
Thankyou very much.

I am definately no expert, but Microsoft has a driver development kit (ddk). You may be able to do something with that.

Hi!
I'm using CDialogSK and I have built a skinned dialog.
Now I want to use Child Dialogs in it, but I don't want the grey background... I tried to use CDialogSK in my child dialog class, but it doesn't work.
Either I wan't to use a small bitmap as the background, or if that doesn't work - atleast have the child dialog transparent so I can just see my controls in the child...
Would this be possible?
Thanks

I dont understand your 100% problem but I guess I did some familar thing some time ago. It was a SplashScreen with Transparency and Controls
(used the CDialogSK class). the problem was, I cant use childwindows because the got the same attributes
from the SetLayeredWindowAttributes call.
So I must create some popup windows and move
them arond if the parent dialog moves.

I realize this sounds idiot, but how do you <subj>?? I can't find any main() or wmain() function in my project and can't acces any argc or argv.
I tried to acces them anyway but they are undefined.
Searching through the SDK I only found 2 functions:
GetCommandLine();
CommandLineToArgvW
First one seems to work but the second I couldn't convince to work. And I surely tried. Simply hates me.
Does anyone have any ideea,
HOW CAN I READ THE COMMAND LINE ARGUMENTS IN AN ARRAY OR SOMETHING SIMILAR TO ARGC AND ARGV?
TIA!!
