What exactly are you wanting to send?

I have 2 windows. In these windows I have a class that I create. This class is exactly the same in both windows. I create the object and I need to send this object from one window to the another window to use it. Actually I'm using unsuccessfully WM_COPYDATA message to send the object. But this is written is MSDN:
"The data being passed must not contain pointers or other references to objects not accessible to the application receiving the data."
Because this, some data in my object are empty.
So, someone suggested me to use serialization, but I'm very very new in this topic...

One of the thread in my application has consumed some windows messages which are aimed to my controls (my own defined control).
Can anyone give me a suggestion what I should do to solve the problem?
|
|
|
|
|
What kind of messages would that be?
User defined such as "WM_USER + X" or "WM_APP + 1"? If so: read this article[^] by Joe Newcomer.
Hope this helps

Thanks Roger. I would read the article.
It is the standard keydown message. I select an item in my list control, then pressed the arrow key up or down, nothing happened in the list control, the selected item has not been changed. I used Spy++ to check and found out that the list control has never recied the key up och down message. The thread which holds the dialog window has recieved the messages, it seems that the thread has consumed the message and never send it to the control. I just wonder why and how I can solve the problem.

What does your thread's message loop look like?

Use "SELECT COUNT(*) FROM table_name" as your SQL statement.

Why not get it into an int, then use CString::Format() to get it into the CString?

Is it present on your machine? You can't run something that doesn't exist?

In the same location as other EXEs that are used by the build process, or any other folder that is part of the PATH environment variable.

Hi all,
In my project we need to disable memory stick as soon as it is connected to the system. For doing this we are using SetupDiXXX win32 api's.
The problem with this is not disabling the memory stick first time which has never connected to the system before. From second time insetion onwards it is successfully disabling the memory stick.
iam using the following code to disable memory stick....
spPropChangeParams.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);
spPropChangeParams.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
spPropChangeParams.Scope = DICS_FLAG_GLOBAL;
spPropChangeParams.StateChange = DICS_DISABLE;
spPropChangeParams.HwProfile = 0;
if ( !SetupDiSetClassInstallParams(hDevInfo, &spDevInfoData,(SP_CLASSINSTALL_HEADER*)&spPropChangeParams, sizeof(spPropChangeParams)) );
else if ( !SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, hDevInfo, &spDevInfoData) ) ;
Any help on this is greatly appreciated..
Thanks in advance

Hi all,
I've got an MFC VC6 project written & compiled for English which is now being used in Germany, and is exhibiting some odd behaviour regarding edit boxes and DDX. I'm using these validating edit boxes, which correctly take into account the locale and accept commas as a decimal point. However, the underlying MFC code isn't taking into account the locale, and is throwing up a validation error when performing DDX to convert the edit box text to a float variable.
Any suggestions as to how I can make MFC use the locale of the OS so that it doesn't throw up this erroneous validation error?
Thanks.
