For example: FDK01, FDK02...FDK09 means key F1, F2.....F9. Now, I want to perform something like when I select FDK01 in the list box and then say OK ..it should then allow me to pressed button 1. How should I code the list box item to perform what I want?
You can use SendInput for this purpose.

I'm trying to write a program that takes input and instantly sends it to multiple windows simultaneously. Ultimate goal is to have 5 copies of Notepad open, typing into one, and the program fills out all 5 Notepad windows without ever changing focus from the initial window.
Unfortunately, I dont understand how to accomplish this because everything I read tells me that you must activate an application beforing using SendKeys or SendInput.
Anyone have some ideas? Has this been done before?

Send WM_KEYDOWN, WM_CHAR and WM_KEYUP messages (in that order) directly to the notepad windows. You don't need to emulate a keyboard - just tell them that a key has been pressed.

Hi I'm currently trying to code a REAL-TIME midi remapper program in Visual C++ using MFC..
I need the program to constantly look for a input midi signal... The only way I have figured out how to do this is to run a constant loop that contains the midipoll(); I've had to set it to only recieve a certain number of signals so it will eventually end.
I works great and recieves all of the messages.. but while in this loop I loose control of the rest of the program... The loop takes over. Is their a way I can do this without loosing control of the program?

Thanks.. that worked out great using a work thread...
Now i'm having a problem accessing the UI from within the thread.. ie. a listbox
I need to send info to the listbox from within the thread.. Any Ideas
this is what I got...
UINT MyThread( LPVOID pParam ); //prototye
UINT MyThread( LPVOID pParam )
{
while(RunThread) {
If (inputdetected){
m_ListBox1.Additem("input detected"); // <-- I don't have access to ListBox 1 from withing this thread.
}
}
return 0; // thread completed successfully
}
I call the thread to start with..
AfxBeginThread(MyThread, NULL);

You can not use the MFC control placeholders from the thread.
Instead, it is better to use the listbox control's window handle directly to add elements to the listbox.
The LPVOID pParam passed to thread could be a data structure, in that data structure, one of the fields could be the window handle for the list box control.
So you call
typedef struct {
HWND hListBox;
} MYSTRUCT ;
MYSTRUCT MyThreadInfo;
MyThreadInfo.hListbox = m_ListBox1.m_hWnd;
then
AfxBeginThread(MyThread, &MyThreadInfo);
UINT MyThread( LPVOID pParam )
{
MYSTRUCT* pMyThreadInfo = (MYSTRUCT*)pParam;
while( RunThread ){
if( inputdetected ){
SendMessage(pMyThreadInfo->hListbox, LB_ADDSTRING, 0, (LPARAM)"input detected");
}
}
return 0; // thread completed successfully
}

This is driving me nuts. I'm trying to call CreateProcess() to start Internet Explorer from within a Manifest-enabled (specifically Common Controls 6) application and I get about 7 dialog boxes that say the exact same thing:
------------------------------
Runtime Error!
Program: C:\Program Files\Internet Explorer\iexplore.exe
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
['OK' button]
------------------------------
After I click through all 7 'OK' dialogs, everything seems to work normally.
The only thing that I've discovered searching Google is that XP Manifests for Common Controls 6 is what seems to be affecting Internet Explorer's startup sequence. CreateProcess() is acting like "if the process starting the new process is XP Manifest enabled, then the new process MUST ALSO be XP Manifest enabled." Now, I know there has to be a workaround because Explorer.exe is XP Manifest enabled and runs new processes all the time (including IE).

1) Use CreateProcess() to start another process besides iexplore.exe.
2) Remove the manifest from your project and then try to start iexplore.exe.
What does this uncover?

I figured out what the problem was. Well, not EXACTLY what the problem was, but it had to do with sending an incomplete set of environment variables to the new process in the CreateProcess() call.
Thanks anyway. The error message had very little to do with the actual problem (which is what was so strange). Apparently IE relies on the Visual C++ libraries in some way that is dependent on the environment variables passed to it.

I need to know how to control a directory structure from the "Open" dialog window from an application. I need to be able to restict the user from going to directories that have been determined they should not enter and restrict them to a certain directory. Anyone have any idea how to do this not in MFC, win32 api format.
Thanks,
|

You can restrict them to a single directory using the OFN_NOCHANGEDIR flag. If you need something a little more complicated then create your own OpenFile dialog.

Wrong. That flag restores the current directory to its original value if the user changed the directory while searching for files.

the hard way would be hooking ZwQueryDirectoryFile and restricting your diretories.
:P
I'm sure there is an easier way

Here is the scenario.
I have a web based email client application I have created on a certain website. Whenever a user clicks on an email address, it will take them to this client and populate the TO field, and maybe even the subject field, depending on the mailto parameters.
I know I'd have to set my default client to this web based client. Does anyone know how to accomplish this or any direction I can be pointed to, to begin? What tools should I use?

I suspect you'd need to make a change to HKEY_CLASSES_ROOT\mailto\shell\open\command.

Yea. I know you have to change the to open Internet Explorer and set it to the respective URL. However, how would you populate the form's fields?
|
|
|
|
|
One way is via the mailto: protocol itself:
mailto:tdnxxx444@codeproject.com?Subject=Test subject&Body=Test body

How would I use the that populate the fields in my WEB BASED email client that I wrote though?
|
|
|
|
|
It looks as though I spoke too soon. You may have to resort to some .vbs, .wsh, or .js file to do this for you.

Okay. Where would the above file you mentioned be locationed? On my website with the email client?
I looked at how they do it for the hotmail client that is built into internet explorer and it seems to use a DLL file. Would this way be easier or the way you mentioned?
This is basically how the flow of events should look so that we are on the same page:
user clicks on mailto hyperlink in their browser ->
another internet explorer opens up and takes them to our website email client application ->
form is populates TO: and SUBJECT: fields based on the paramaters of the mailto hyperlink
I guess I am confused as to how the "mailto" hyperlink would communicate to internet explorer and to our website that the user is taken to, these respective parameters.
