I don't understand why you need draw it from document.Set value in the doc,call from doc to updateallviews and in the view OnDraw call to
and call to dc->textout(pdoc->getvalue()).
Good luck. Mad | :mad:

GetDC() will return the pointer to the Current Device Context..

Bear with me here, so you call GetDC() and then you assign this to pDC correct?

Would the code look like this?

GetDC()* pDC;

How do you tell which document is active or do you need to?

YES!!!!!!!!!!!!!!!!

I found a command that worked!!!!

Since I'm using an EditView this function works:

void CMyAppView::OnTestingInserttext()
{

CMyAppDoc* pDoc = (CMyAppDoc*)GetDocument();

CString outtext;
CEditView::GetWindowText(outtext);

outtext=outtext+"This is my new stuff";

CEditView::SetWindowText(outtext);
pDoc->UpdateAllViews(NULL);

}

Thanks again for all your help, I simply stumble across the GetWindow text while looking for CDC information. Cool | :cool:

Good. Now try checking out CEdit::ReplaceSel function. It is more efficient than getting the current text into a string and appending and sending back to control. You will also need to look at CEdit::SetSel.

Since you are using an EditView you don't need to write directly to the DC.
Instead write to the EditView using SetWindowText.

Oh sure, now you tell me Smile | :)

I found it before I read any replies, but thanks for offering advice. Now the next question that comes to mind is, what is all that DrawText and TextOut used for?

Also, I know how to pass a variable from a modal dialog, how do you pass one from a modaless? Or should this be under a new thread?

How to draw superscripted/subscripted text

DrawText and TextOut are used when you need to paint directly to the window. If you are using an edit control then the edit control will handle drawing directlty to the window, all you need to do it tell it what text to draw.

Matt Fenwick wrote:

The variable must be a public member of your dialog class. Then you can access the variable from anywhere. Or you can create it private/protected and make a public function to retreive it. It is the same in modal/modeless.

I looked everywhere fonts, text api's but could not find a flag to set in order to draw text as superscript or subscript (using GDI). How is it normally done?

halve the font size and offset if necessary.

I develop my application on my computer. Everything is OK.
but when I copy my application (.exe and .dll) to the another computer. It occur "Application Error" if I ran it

this is full error message

What's wrong ?
How could I do ?
Thank you so much for your kindness

Have you distributed the release or debug build ? Have you run both builds on your own PC ? Have you tried commenting out different bits of code until you can establish which code is crashing through a process of elimination ?

I'm guessing not.

Do you expect me to tell you what the problem is, when I don't even know what framework you're using, your dependencies or what your code does ? Even if I did, I doubt I could answer. Do what I said - comment out parts of the code that might cause such an error ( for example are you creating any COM objects and not checking them before you use them ? ) and then let us know if you find the code that is breaking and still cannot figure out why. I'd love to help, but you're simply not giving me enough information at this stage.

I'm sorry that my information is not enough.

More information
1) My computer has 2 OS (Windows 2000 Advanced Server
and Windows 98 SE). I develop on windows 2000 Advanced Server
and It's work. after this I copy my app and the Dependence
to Window 98 and run it.(it's work)

2) The another computer that I try to run is
Windows 2000 Profressional)

3) My Application (Screen Mate) does as following;
- Windowless
- SetWindowRgn
- Draw Bitmap on Window Region

Thanks a lot for your kindness

Christian Graus30-Jun-02 18:21

Work backwards then - do a build without the draw, see if it crashes. The don't set the region, see if it crashes. Then you can figure out where the problem is.

Either install what you need to debug or do remote debugging.

I'm sorry for posting so much code, but since i really dont have any idea why is isn't working I dont know what to show and what not to.

Using the debug tool I have managed to figure out my app crashes at run-time when it executes this line

int int_mode = 0;
CString str_buffer;

if(int_mode == 1) //this is the line that, once executed, crasehes the app

im sure there is something I dont know im doing wrong, so please enlighten me Smile | :)

its been driving me crazy most of the afternoon.

int format_chars(int int_offset, CString input)
{
	int i = 0;
	int a = 1;
	int output = 0;
	int int_mode = 0;
	CString str_buffer;

	while(true)
	{



		if(int_mode == 1) //crashes after this line
		{
			if(input.GetAt(i) == ' ')
			{
				output = atoi(str_buffer);
				return output;
			}
			str_buffer += input.GetAt(i);
		}

		if(input.GetAt(i) == ' ')
		{
			a++;

			if(a == int_offset)
			{
				int_mode = 1;
			}
		}
			



		i++;

		if(i > input.GetLength())
			return -1;
	}
	 

	return -1;
}

Re: run-time error if statment

30-Jun-02 14:44

if(i > input.GetLength())

should be if i >= input.GetLength(); For efficiency you should also put this value into a const int prior to starting your loop.

The reason for >= is that the string is zero indexed, so a string with a length of 5 has only values up to [4].

if string = NULL or empty so CString::GetAt(0) raise assertion.
So first you need check if it not empty and i < CString::GetLength() Mad | :mad:
