Dear Sir, my problem have not solution up to now.
For example; my button have IDC_Button identifier,
I want that if values on two edit controls are equals, automatically there is a click on my button to confirm the result.
What to do it ?

I guess the answers you got in your previous thread here[^] didn't help you.

What do you mean by "automatically"?
You have to write code that verifies that the contents of the two edit controls are the same.
If the ID of your button equals IDC_SHOW, then you could "simulate" a click on the button by sending or posting a WM_COMMAND message to the window that contains the button, like this:
PostMessage( WM_COMMAND, MAKELONG( IDC_SHOW, BN_CLICKED ) );

Thanks for your reply, I wanted this code you send me.
I try it, it's work very well.
Thanks a lot

That's nice, but why do you think that you cannot simply call the message handler directly like you were suggested by baerten in your previous thread and by David below?
Is it a threading issue, another window or what?
As I understand it you would check the contents of your two edit controls in a call chain originating from EN_CHANGE event handler for the edit controls. The most intuitive solution would be to call the event handler for the BN_CLICKED event of your button.
My point is that it's unnecessary to cross the river in order to fetch water.

Dear Sir,
Thanks for your interesting to my idea.
I am in the same formView and in Edit change of my edit control I want to send a Clic on my button.
In previous reply, I did n't have exactly the code to write, but in your reply it's very clear for me.
If you found the next reply good for you can explain me clearly with clear codes.
Thanks

You can use of call message handler of button.

Why don't you just call the same function that your button-click handler would call?

Hi All
I am making one console application.
I am using getche() function to retrieve a character from console input buffer.
Now I am getting unhandled exception when I run the code.
I am aslo using standard handle for input and output for some other requirement.
I am wondering if these handles are causing problem.
I have removed these handle part from my code.
But still my console application is giving me the same problem.
I viewed call stack , it is showing me some "lock" problem.
So I restarted my computer but it has solved my problem only once.
Now i am again getting the same problem after restarting the computer.
Can anyone help in theis !!!!!!!!!!!

Just show the part of the code with the getch() and the exception.

edit your message and use <pre></pre> tags around your code.
and try to use your debugger to figure where the code fails exactly...

sachin ahuja wrote: A lot of code
Ok, where is the exception coming up?
Certainly not in the piece of code you showed. Most of it is commented out and the other part is not compiling because Initialize() is missing.
So, please use the debugger to find out which line is crashing and prepare a running, minimal program demonstrating the error.
And, as toxcct said, put your code in the pre - tags by marking it and then clicking on "pre". On your screen just above the line with the smilies.
I turned your code into a working mini-application:
#include <windows.h>
#include <conio.h>
#include <string>
int main(int argc, char* argv[])
{
std::string sData;
int Error;
int i = 0, j = 0;
COORD origin={0,0};
char sIniPath[100];
const int ERR_HT_HANDLE = -1;
CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
int ch = ::getche();
HANDLE hStdOut = ::GetStdHandle( STD_OUTPUT_HANDLE);
if(INVALID_HANDLE_VALUE == hStdOut) {
Error = ERR_HT_HANDLE;
}
GetConsoleScreenBufferInfo(hStdOut , &ConsoleScreenBufferInfo);
ConsoleScreenBufferInfo.wAttributes = FOREGROUND_GREEN;
SetConsoleTextAttribute(hStdOut ,ConsoleScreenBufferInfo.wAttributes);
HANDLE hStdErr = GetStdHandle( STD_ERROR_HANDLE);
if(INVALID_HANDLE_VALUE == hStdErr) {
Error = ERR_HT_HANDLE;
}
GetConsoleScreenBufferInfo(hStdErr , &ConsoleScreenBufferInfo);
ConsoleScreenBufferInfo.wAttributes = FOREGROUND_RED;
SetConsoleTextAttribute(hStdErr ,ConsoleScreenBufferInfo.wAttributes);
HANDLE hStdIn = GetStdHandle(STD_INPUT_HANDLE);
if(INVALID_HANDLE_VALUE == hStdIn) {
Error = ERR_HT_HANDLE;
}
}

my code is giving problem before initialze function is called.
it is giving me problem on 10th line number ( int ch = ::getche();).
The code crashes here only.
I have seen the call stack which is given below
NTDLL! 77f69ecd()
NTDLL! 77f5b2e6()
_lock(int) line 228 + 7 bytes ********The problem is basically here.
_getche() line 254 + 7 bytes
main(int, char * *) line 56 + 5 bytes
mainCRTStartup() line 206 + 25 bytes
KERNEL32! 77e735dd()
After debugging the application I came to know that there is some problem related to multi threaded.
I have checked all my project settings but all entries are for single threaded wherever required.
Please see initialize() function if it is required
int Initialize()
{
//File Opening
int Error = SUCCESS;
fp = fopen("C:\\log.txt","w");
if(fp == NULL)
{
Error = FAILURE;
printf("Error in opening file\n");
}
return Error;
}
But the code is not reaching here.
I am getting problem before this function.
Kindly see if the problem can be solved.
Thanks in advance.

Even that can not be, as fp, your result of fopen(), would be undeclared.
Are you using fclose()?
But first and foremost:
When the first statement in your app crashes, there is something very rotten.
Are you doing some funny linking?

Yeah I am able to solve this issue.
Actually I am linking two libraries in this project which are multi threaded.
And my application(console) was single threaded.
So i have made my application(console) also multithreaded.
Now it is working fine.
Thanks a lot for your kind support and time.

Great!;)
And thank you for giving feedback.
Multi/singlethreaded linking usually shows characteristic (but misleading) linker errors. But this...
