Use GetWindowText() in MFC or handle the WM_GETTEXT message in win32
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.

Thanks everyone....I was using GetLine, didn't realize until right now that was only for multiple line boxes.
can you tell i am new to programming?!?!?!
In another case, I will have a number. Is there a way to determine if this number is a negative? How do I just look at the first character in the string?

Use atoi() for an int or atof() for a float and check if the number is less than zero.
<br />
CString str = "-9";<br />
int value = atoi(str);<br />
if (value < 0)<br />
{<br />
.....<br />
.....<br />
}

Thanks....
Is there a place where I can find all these types of conversion "tool/methods"? I know what this one does (atoi) but I know there are other ones that I may find useful.
Many thanks again.

Not unless you tell us! Even experienced folks forget stuff now and then.

I want get a associated icon from a file system (for example c:\test.doc") using SHGetFileInfo function and save it in a file (for ex "C:\myicon.ico").
But GlobalSize and GlobalLock returns 0 (invalid value!!!).
I've read an IconPro example (in vs6example.exe) but I didn't found a good solution!
Please give me a good idea!
Tnk you
/******MY CODE*****/
CString nomefile = "c:\\test.doc";
HICON hGen32Icon;
HIMAGELIST hSysImageList;
SHFILEINFO shfi;
int fh;
UINT uiSize;
DWORD dwSize;
LPVOID lpGMem;
OFSTRUCT of;
hSysImageList = (HIMAGELIST)SHGetFileInfo
(nomefile,
0,
&shfi,
sizeof (SHFILEINFO),
SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
hGen32Icon = ImageList_GetIcon (hSysImageList,
shfi.iIcon,
ILD_NORMAL);
dwSize = GlobalSize(hGen32Icon); /*Don't work*/
lpGMem = GlobalLock(hGen32Icon); /*Don't work*/
fh = OpenFile ("c:\\myicon.ico", &of, OF_WRITE | OF_CREATE);
if (fh == -1) // If NOT opened successfully.
{
MessageBox("Unable to create file", NULL, MB_OK );
}
uiSize = _lwrite(fh, (LPSTR)lpGMem, (UINT)dwSize);
_lclose(fh);

I want to draw a picture , in which one color must not be drawn,
-transparent color,
but at usual samples I must redraw picture fully transparent - get background,
repaint at transparent places,
and than only paint picture.
Here I must REALLY redraw more one time full place- that is visible like flickering.
Is it possible to redraw trabsparent bitmap with no repaint?
Or is there e else method without flickering?
(BeginDraw()
EndDraw() -do this? )
Does standart dc.TransparentBlt() draw with no flickering?
thanks you
|
|
|
|
|
You could draw the background onto a memory dc, draw your transparant picture to there, then bitblt to the screen, and handle WM_ERASEBKGND there ofcourse to prevent the flickering.
|
|
|
|
|
But how can I get background - if not repainting my picture
invisible first?
That is problem!
|
|
|
|
|
he means draw ur background image into a memdc THEN draw ur transparent image over it into the same memdc (avaoiding drawing the color u dont want to see) then bitblt it to the screen
if u dont have a background image u want to see underneath the transparent image why bother with transparency?
hope that helps

fisrtly how do i make arrows, lines, circles or squares objects that i can
cut and paste and copy, then with that it would help me being able to save the diagram in xml, but not in diagram format but in code. this will help me
edit the loaded version of the diagram, ie cutting and pasting lines and squares that were loaded from a saved diagram....an argoUML use case project
smile...its your destiny

|
|
|

Please clarify. Do you want to write a program that lets a user draw lines and arrows that can be edited and be saved to XML?

I created red bimap,(0000FF)
get it's pixels by following code,
but method showes pixels is blue (FF0000):
How order of colors and bytes myst be read to make getting color
and place of pixel correct?
<br />
BITMAP bm ;<br />
DWORD* pBits;<br />
<br />
GetObject(hBitmap, sizeof(BITMAP), &bm);<br />
<br />
pBits= new DWORD[bm.bmHeight*bm.bmWidth];<br />
<br />
memset(pBits, bm.bmHeight*bm.bmWidth ,0);<br />
<br />
<br />
GetBitmapBits( hBitmap, (bm.bmHeight*bm.bmWidth*4), pBits );<br />
<br />
COLORREF* pCr;<br />
int bt_cr = bm.bmBitsPixel/8;
<br />
<br />
for(int h =0; h < bm.bmHeight; h++)<br />
for(int w =0; w < bm.bmWidth; w++)<br />
{<br />
<br />
<br />
pCr = (COLORREF*) & ((BYTE*)pBits)[ w* bt_cr + h*bm.bmWidthBytes ];<br />
<br />
<br />
BYTE pureR,pureG,pureB;<br />
pureR =GetRValue(*pCr);
pureG =GetGValue(*pCr);
pureB =GetBValue(*pCr);
<br />

Each pixel has BGR format. I know this from bitmap displaying in OpenGL.

Right answer is:
to a 32 bit dib, the order is XRGB.
to a 24 bit dib, the order is BGR.
But to a 16 bit dib, there are two types.
X555, 565. I don't know which one is correct or which one should be by given a dib. Maybe who can tell me.

Each pixel is COLORREF value. sizeof(COLORREF) is 24.
24/3=8. It means, that you can describe each pixel with three 8-bit values. So, naturally, you have only 24-bit dib in bitmap pixel array. And it is true.

8-bit and 16-bit dibs are indexed, they are not rgb values. Read all about them in the Petzold.

I do not works with DIB,
just need correctly proceed 24 and 32 bit BITMAPS only.
Do you think despite all samples did for bitmap,
DIB much better dor speed and suitability?

Well yeah but you mentioned 16-bit bitmaps so I figured I'd correct that...
As for ddb vs dib, I find it easier to work with ddb's (they're faster too) but when you have a very large bitmap you may run out of video memory... It all depends on your application, basically.

Hi everyone,
I wanted to know if someone could help me. I have a project with three different classes for three different dialogs(3 .cpp files). I have a variable that the user enters, which is in one of the classes (dialogs). I want to use that same variable with the stored information in my other dialog(class). How do I do that?
Someone told me to pass a pointer, but i don't know how to exactly do that cause i get some error when i run the program.
Thanks for helping me.
Jimmy
Just cause I am 15, doesn't mean I'm dumb! (I'll really be 4 on Feb. 29...the year 2004)

1) You can declare your variable in global scope.
2) You can use pointer to the variable in the first class in the last two classes.
