Hello,
I am hosting an activeX control that has its own UI using standard MFC controls. I have a button that has an accelerator key ("&Browse") but the button is not responding to alt+b.
I don't know what the problem is. Perhaps the accelerator message is going to the hosting application and not the activeX control? The accelerator key never works, even when a control in the activeX control has the focus.
Any ideas?
thanks!

I'm getting a strange problem that I don't know how to find out what is causing the problem. It's late in this programs' development and I can now use it for it's actual intended purpose instead of testing functionality. After I run it for a while, it slows down and I click Stop in VS. A lot of these come up in the debugging output window:
First-chance exception at 0x7c81eb33 in myprogram.exe: Microsoft C++ exception: CResourceException @ 0x0012f660. Warning: Uncaught exception in WindowProc (returning 0). I know how to handle exceptions but I don't know how to find out where the exception occurs so I can either fix it or catch it and then handle it properly.

Are there any localization tools which would indicate a resource in one language to change when the same resource id is updated in another language in the same RC file?

Okay, a little problem here, im doing the following code, all in the same scope:
char* data;
...
data = (char*)malloc(sizeof(char));
memset( data, 0, sizeof(data) );
...
if( data != NULL )
{
free(data); // error here
data = NULL;
}
And i get a debug error, "DAMAGE: after Normal block(#371) at 0x0037F9B0."
Any ideas why im getting this?

|
|
Also, at the point where free(data) is called, data = 0xcccccccc.

Your problem:
// This allocates ONLY 1 byte, why you try to allocate only 1 byte??
data = (char*)malloc(sizeof(char));
// However this is memsetting 4 bytes which is whats causing the problem...
memset( data, 0, sizeof(data) );
// Code should read, only set up 1 byte
memset( data, 0, sizeof(char));

wow, dumb error, thanks alot.

Have you considered using new/delete instead?
|
|
|
|
|
memset( data, 0, sizeof(*data) );

Hi,
I work on a large App created using C++ in VS6. We have since moved to .Net and our code is unmanaged. Several of our dialogs have an overwhelming number of controls. I have been tasked to create a wizard which will walk the user step-by-step through completion of the dialog. The current dialog must stay in tact while the wizard will break the dialog into smaller "user friendly" chunks with explanation text. The idea is to have only the current dialog for experienced users and the wizard for new users. The user will have to add text to edit boxes and select from combo boxes etc. I have to do this for several dialogs. I'm trying to figure out the best way to do this without duplicating work. I'm toying with the idea of using a property sheet.
Suggestions??
Thanx

The EnumProcesses function in the PSAPI library enumerates processes. Unfortunately, it does not include in that enumeration processes run by other users. Does anyone know of a way to enumerate all the processes in the system?

probably you can do it only if you have admin rights.

Thanks for your response.
In this case, administrator rights doesn't appear to help (the logged-in user is an administrator).
I've found an alternate method of resolving my issue (it involves an installer for a service that runs under a separate account) using the service control manager directly.

Hi Mr. Gary,
you can try CreateToolhelp32Snapshot(..),Process32First and Process32Next api

Hi,
I am a bigner in VC++ programming (started lerning only in March 2005 with visual stdio 6).
I request some help.
I have created a small database related application for a friend using CDAORecordSet. I made the data connection to Access (ie data is stored, added to and retrived from an access file and displaed on to a listView). I build the application seting the build configuration as 'release'. Then I copied the exe file and the access file on to my friend's computer and tried to run it.
I get the message "Unable to initialise DAO/jet engine".
Please tell me what to do now? Do I have to incorporate the jet engine in the program. If so, how do I do it? Or is there something else that must be done, like create a setup file.
Please, someone, tell me what to do? I really need some help.
Thank you,
Tara

 You have to check register "HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\3.5\Engines exists"
If you don't have this fold you have to install Jet Engine. It's depend on OS you can get download in this site http://www.microsoft.com/downloads/results.aspx?productID=&freetext=Jet%204.0%20Service%20Pack&displaylang=en[^]
One more thing is before check DAO/Jet infromation
bool DAOInstallCheck()
{
HKEY hRet;
bool bBool=false;
if (RegOpenKeyEx(HKEY_LOCAL_MACHINE,
"Software\\Microsoft\\Jet\\3.5\\Engines",
0,KEY_QUERY_VALUE, &hRet) == ERROR_SUCCESS)
{
bBool = true;
RegCloseKey(hRet);
}
return bBool;
}
if DAOInstallCheck())
// Message Return Install require
else
// DAO already Install
Have a nice day

Hi,
I'm trying to show a bitmap image (blended) over a background video using VMR9, this works fine... 
Except,
The bitmap is only visable in the areas of the client window which the video is covering. (as the video is letterboxed). 
Is it possible to allow the overlay bitmap to fill the entire window...
And if not, what over approach should I be looking for to acheive this?
Thanks...
Simon.

|

ooook... figured it out
I've turned off letterbox mode, and manually resized the video itself into the client area, this allows the VMR to render the bitmap to the entire client area.... 
Thanks for listening

Thanks for letting us know the solution - I sometimes look here to see common problems (and solutions) that people come across.

Hi,
My clients like to see the texts instead of the dimmed texts on disabled controls such as check box, radio button, combo box, and edit box in a C++/MFC dialog box. The texts on enabled controls are black.
In order to differentiate disabled controls from enabled controls (black texts), I would like to add some color (blue) on the disabled control texts.
Can you tell me the existing or potential solutions?
Thank you very much!
Shelley

This would seem to be counterintuitive. For example, say you set the text of these disabled controls to red, and the user went in and changed their theme to display red text for controls. How would they differentiate between a disabled control and an enabled control?

Hi,
I have a jpeg file. I would like to embed some text to it.
The text messages will be right above the jpeg image.
For example:
Smiley face
Can someone g:|ive me some ideas about how to do it?
Thanks,
Kevin

read the jpeg.
allocate a temp image large enough to hold the jpeg, with extra space at the top for the text.
overlay/merge the jpeg onto the temp image.
draw the text at the top of the temp image.
save the temp image.

Hello,
I need to set a button as a default button (get's pressed when ENTER is pressed). I'm not using CDialog, so SetDefID is out.
I can subclass the controls in the view and have them post a message to the parent when ENTER is pressed, but there must be a better (more simple) solution.
Any ideas?
Thanks!
