yes it's working but when i write more than 50thousend rows in sheets(more than one sheet) then it's showing error.

Unhandled exception at 0x7c812a6b in Excel.exe: Microsoft C++ exception: CMemoryException at memory location 0x0237e2b4..
In dbgheap.c line  pvBlk = _heap_alloc_dbg_impl(nSize, nBlockUse, szFileName, nLine, errno_tmp);

Can you give me tips for that?

I'm not sure how is it implemented (I think that it does not free the heap memory until the last bit is read into its buffer). You might want to take a look at the code and modify it to add some sort of paging mechanism.

Have you tried XLW? Is that not working as well?

Calling A While Loop On Form1_Load

Hi, in my Form1_Load thing, i'm trying to call a function with a while loop in it. When I run the program, it will just circulate through the loop over and over again, and the form won't load.

Here's the function I'm calling: (Yes I know it's an infinite loop)

<br />
void myFunction (void)<br />
{<br />
while (1)<br />
{<br />
MessageBox::Show("Example", "Title");<br />
}<br />
}<br />
<br />
and in Form_Load I just have<br />
<code><br />
myFunction();<br />

How do I do this so that the form loads first?? Thanks.

You may post an application defined message from within your 'Form1_Load thing'. BTW what on earth is 'Form1_Load thing'?

you call the message-box over and over again...
that is absolutly what you wrote: while (1)

comment the while out:
//while (1)
so you call the Box once

havent you step with the debugger trough your code. Mad | :mad:

public bool bFirstTime;
void Form_Load()
{
bFirstTime = true;
myFunction();
}

void myFunction()
{
while (1)
{
if( bFirst )
{
MessageBox::Show("Example", "Title");
bFirstTime = false;
}
}
}
Now it will be called only once Smile | :)

Do you want to show a message box after the form loads?
If so use the Form_Shown event and don't use the while (1) loop.

You can either dynamically create and destroy a new window or you can pre-create a window and keep it hidden to show when the time comes.
