Hi,
I tried another way and it did work!
I used EnumChildWindows function to enumerate all child windows of the dialog and I could get the handle of the edit control through a callback function.
Thanks for help.

Does anyone know how to close a modem connection? The connection was opened by the user, so I don't have a handle to it. But my app needs to hang up the modem when it terminates.
Afterthought:
I guess I need to query the state of the list of RAS connections and hang up the one that's active. Have to go find some RAS code at CP...

I wrote a function that disconnects the modem:
#include <windows.h>
#include <ras.h>
void HangUp(){
RASCONN *rasc=malloc(1000);
DWORD bs,nc,i,j,dwRet;
RASCONNSTATUS rcs;
MSG msg;
TCHAR s[257];
rcs.dwSize=160;
rasc->dwSize=412;
dwRet=RasEnumConnections(rasc,&bs,&nc);
if(!bs)return;
rasc=realloc(rasc,bs);
if(RasEnumConnections(rasc,&bs,&nc))
return;
for(i=0;i<bs/412;i++){
HRASCONN hrc=rasc[i].hrasconn;
dwRet = RasGetConnectStatus(hrc, &rcs);
if (dwRet != ERROR_INVALID_HANDLE){
RasHangUp(hrc);
while (dwRet != ERROR_INVALID_HANDLE){
while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)){
TranslateMessage(&msg);
DispatchMessage(&msg);
}
dwRet = RasGetConnectStatus(hrc, &rcs);
}
}
}
free(rasc);
}

Sorry for msg below, i forgot to disable HTML.. Anyways, read on...
This function uses RC4's algorithm, but its not working properly. It works on small strings, but not large binarys. I cant find the bug in it.. Its tickin me off! Do you see anything wrong?
Usage;
strcpy(buffer, "This is my test string");
EncryptRC4(buffer, strlen(buffer), "secret", 6);
// buffer is then over-written with the new encrypted string.
// to un-encrypt, just call it again.
EncryptRC4(buffer, strlen(buffer), "secret", 6);
// buffer now holds orginal message.
// using strlen here isnt smart, because NULL character may be generated somewhere in the string buffer, but it fits the demo.
Function;
void EncryptRC4(char *sBuffer, int iBufferLen, char *sKey, int iKeyLen)
{
unsigned char sBox[256], k;
int iOffset, i = 0, j = 0;
for (i = 0; i < 256; i++)
sBox[i] = i;
for (i = 0; i < 256; i++) {
j = (j + sBox[i] + sKey[i % iKeyLen]) % 256;
k = sBox[i];
sBox[i] = sBox[j];
sBox[j] = k;
}
i = 0; j = 0;
for (iOffset = 0; iOffset < iBufferLen; iOffset++) {
i = (i + 1) % 256;
j = (j + sBox[i]) % 256;
k = sBox[i];
sBox[i] = sBox[j];
sBox[j] = k;
sBuffer[iOffset] = sBuffer[iOffset] ^ sBox[(sBox[i] + sBox[j]) % 256];
}
}

Ok, I'm an idiot! That function works perfectly! I just realized after 2 days of debugging, that the function is perfectly fine... it was that I was using the 'get' member function instead of the 'read' member function of the fstream class.... So i was reading the file in wrong... so it was encrypting the wrong data... LOL ... Blah! Basically the obove function works perfectly for anyone that would like to use it.

Ok, I simplified it down to just a function instead of a class. This function uses RC4's algorithm, but its not working properly. It works on small strings, but not large binarys. I cant find the bug in it.. Its tickin me off! Do you see anything wrong?

Hello,
i am somehow new to C programming.
i did a plugin (DLL) written in C and now i need to write an EXE that has to send events to that DLL. I read some articles and i think the best way is to do that with shared memory. There are some articles around with code samples but all use MFC which is not supported in C
Can someone pls provide with me with information how to do that in C? Maybe there is a library that may makes things a bit easier?
Thanks for you help

Why do you need to send events to that DLL. Why not load it from your exe directly?
Best regards,
Alexandru Savescu

Your question is a little blurred and i'm not quite sure on what your'e trying to accomplish.
But if you want to share data sections in a DLL then you could do something like this:
#pragma data_seg(".sdata")
int iSharedVar = 0;
#pragma data_seg()
Remember to modify your .DEF file:
SECTIONS
.sdata READ WRITE SHARED
The recommended approach though is using file mappings, this is by the way the underlying technology for the implementation of eg. pipes on Win32. Look up CreateFileMapping and MapViewOfFile in MSDN for details.

thanks for for reply
okay, sorry i try to make it a bit clearer.
The plugin (DLL) is for a program I use (it's not written by me). The DLL is not for EXE i want to write. The EXE is to control the other program (which loads the DLL) via the plugin. Therefore I need IPC because it is 2 different processes.
"Application.exe"
loads DLL <------ "control.exe" sends events to DLL
i hope this helps

If i understand you correct:
You have written a plugin P, the DLL.
The plugin corresponds to a plugin standard known to the application X that loads P.
You want to send a message to P that will somehow be detected by X.
In that case any of the methods i described are valid, by the way, remember to use some sort of synchronization when using mapped files or shared sections. You could take a look at CreateMutex in MSDN.
Hmm..., I guess i didn't tell you how to set up the loop that checks for the shared data to change, but why spoil all the fun.
But here is a hint: Loop could be set up in DLLMain(), remember to Sleep() sometimes so you won't get exhausted...
You could probably also use som Win32 Event functionality, but I haven't actually got any experience in this, but looking up CreateEvent in MSDN seems like a good idea (just did that and it seems to be what your'e looking for).

Hello,
Can anyone tell me how to convert CString to char*?

did you try (char *)csMyCString ?
