What does 'dump' mean. Do you want to clear the text box ? Do you want to grab all the text to a string ? What ?

Maybe he wants to display one of every character in the full character set in his text box?
Maybe he solved it himself already.
Doesn't look like he's going to tell you, though.

How do i write text on a bitmap file where only the path of the bitmap file is given?
|
|
|
|

If it's a bmp, LoadImage will load it. Otherwise, GDI+ will probably load it. Then you need to select it into a DC, draw text on it and save it again ( which probably means you need GDI+ and will load it into a Graphics object ). I have several articles on gDI+ here, one of them is called 'doodle' - it will show you how to load and save an image, and draw on it. Just change the code to draw text instead.

I cant find the the article... would u mind giving me the link?
Its a bmp but not not necessarily in the resource folder...
|
|

|

I don't see how you could miss it. I typed 'doodle' in to the search and it was the first hit. You could also click on my name and 'view articles'.

The bmp would have to be on disc, not a resource.

CImage m_Image;
m_Image.Load("d:\\picture.bmp");
in the function OnPaint(event WM_PAINT)
CPaintDC dc(this); // device context for painting
BitBlt(dc.m_hDC,0,0,800,600,hdc,0,0,SRCCOPY);
dc.TextOut(40,40,"test",5);

Hey, just trying to use a variable to hold multiple values so that I can then send those values back to my originating app. I have three values that I need to store in my variable before I return it.
I am using something like this:
for(d=alldevs; d; d=d->next)
{
if (d->description) {
strcpy(descp,d->description);
//strcpy(dev,descp);
}
}
return dev;
If I uncomment the commented line, I see only the second value, if left as is, I see only the first value, I of course, want all three or as many as there will be --probably no more than three. I am trying to enum the adapters in the system, btw.
Any help is appreciated, as always. If you need more info, please let me know. have a good day and thanks in advance.
EDIT: figured it out --I used strcat instead of strcpy and it works. thanks anyway.

I need some help getting a edit window to select, copy and paste text.
An article on the subject would be helpful or an example of code.
Thanks

How do you mean ? You have an edit control and you want to select and copy text out of it ?

Hi guys, I have a problem concerning a constructor.
I have a code like this:
CClass *pClass;
pClass = new CClass();
pClass->CClass::CClass( param1, param2 );
CClass has 2 constructors, the first called with new, and the second one has to be called after it.
The VC compiler accepts this syntax, but GCC does not.
What can I do? Redesign won't work, I need it exactly like this!!
Thanks for advice,
Alex

Simply speaking, you can't. I am actually surprised that it compiles with VC++.
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

I have to and I know that it works for GCC, too... I just don't know the syntax, that's the problem.

You are not really calling 2 constructors, you are only calling one, then calling an function, which happens to be an overloaded constructor.
Overloading functions is ok, but some compilers will complain if you try overloading a constructor. Perhaps you should create just the one and pass null values to the first call.
I'm curious to know why you need it to be like this?
|
|
|
|
|
CClass *pClass;
pClass = new CClass();
pClass->CClass::CClass( param1, param2 );
What is it you are trying to do here? You are creating a pointer to an object, calling its default constructor which should be
pClass = new CClass; then trying to call it's overloaded constructor. You can only call one of them, calling the second will only initialise a new object. I'm surprised this compiled.

nop walder, this line is correct.

you must know that some constructors can be declared as explicit, and such constructors cannot be called without parenthesis !!!!

there is no way to re-design it.. i need it exactly as i described!!! i solved the problem using inline assembler now, but it is not the best solution i think. The problem is not the overloaded constructor. the problem is, that the GCC does not want me to call a constructor.

You could try using 'placement new'.
e.g.
new(pClass) CClass(param1, param2);
...cmk

Why would you want to do such a thing?

perhaps you could search google for some C++ tutorials, there are many tutorials available for both beginners and professionals, ranging from creating a simple text editor to reprogramming your mothers hairdryer.
This one here[^] covers most of the basics.

Hello all.
Let's assume I have commands like this:
"c:\Program Files\Product\command.exe" -arg1 -arg2
\\.\c:\Program Files\Product\command.exe -a 1
I would like to know how to extract the "command.exe" part from whatever possible command syntax Windows allows.
Thanks all.

Wont argv[0] give you the exe name .
int main(int argc, char* argv[])<br />
{<br />
char *exeName = argv[0];<br />
TCHAR szFileName[_MAX_PATH];<br />
_tsplitpath( exeName , NULL, NULL, szFileName, NULL );<br />
return 0;<br />
}
// after seeing michael answer it striked me you were looking for the exe name
Regards,
FarPointer
