Try the graphics library CxImage, available on CP. http://www.codeproject.com/bitmap/cximage.asp
or www.libtiff.org and get the tifflib library, CxImage uses this library as well

I would like to ask you what is the best best way to store information like, for instance, user preferences, on a CFormView project.
Serializing would make it but i do not know how to make avoiding the Open/Save dialog.
It woul be nice if you could help me.
Thanks in advance

Hi,
Is it possible to search for a text written on a bitmap.
If possible tell me If we can search text even if the bitmap can be stretched.

Who wrote the text on the bitmap?
If your program did the writing, then you need to record the text and where you wrote it. From there it is smiple.
Search any bitmap?
You need an OCR library ($$$) to search the bitmap, and there is no garantee it will beable to find the string. An OCR library should not care if the bitmap is strected.

Hi,
Thanks for your reply.
Unfortunately I am not writing a Text in Bitmap.
Where can I find this OCR Library.
Do we have any support in Windows for such type of operations.
Thanks & Regards

Hello,
I have been given a program consisting of several C written modules (neither C++ nor C#),
I want to edit/debug/execute so as to understand what it does and how it works, in the easiest and quickest possible way.
Which product/package would you advise me to use ?
Regards?

Your best choice would be an IDE (integrated development environment). IDE's typically include a syntax-highlighting editor, compiler, and debugger. The most prominent IDE in the Windows world is Microsoft Visual Studio. Most C++ tools will work just as well with C.
You can check out a list of IDE's at Programmer's Paradise here[^]. They also sell tools here[^] and here[^] that help with analyzing code.

Any IDE that recognises a 'C' module and has edit/debug capabilities; preferably the one that is going to be used to compile the final code.
To fully understand how the code is supposed to work, I reccomend testing it using the origanal IDE (if any, and available).

What to use and how  to display postscript file in my win32(gui) application ?!
|
|
|
|

You could look at hosting the GhostScript DLL, which will do all the rendering for you.

Rather than using a CListBox control, you would be better off using a list control. An example of a list control is the right hand pane in Windows Explorer. When it's set for the details view, the list control is in report mode, which supports multiple columns. Try Matt Weagle's article[^] here on Code Project. It gives a basic introduction to using the list control.

I just wish to have 2 dialogs in my MFC prrogram:
when I click "next" in dialog1, then dialog1 disappear and replaced with dialog2. that's it.
how can i do this?
I am new to MFC... would any one pls help??
Many Thanks!

CMyDialog1 dlg1;
CMyDialog2 dlg2;
int result = dlg1.DoModal();
if (result == NEXTCLICKED) {
dlg2.DoModal();
}CMyDialog1 and CMyDialog2 are the dialog classes for your two dialogs. NEXTCLICKED is a constant value. In your 'next' button handler in the CMyDialog1 class, call EndDialog(NEXTCLICKED);.

Consider use of tab control, for example this is the way for building wizards

 Hi! My name is Jarett - a budding MFC programmer!!! yay.
Anyways, I am having some difficulties getting rid of some flicker. Now, before ignoring the rest of this, and telling me to look up info on the net; I have! And I am at my wits end. Nothing seems to refer to my specific issue. Here's my program (I know, it's long and boring).
Before reading any code, let me explain my idea (if the code isn't clear enough). The idea is this: It's battleship. Battleship has a board for both players (computer, and human in this case). Each board has cells (or places for pegs and ships). each board also gets five ships (duh). Now, I want to have the program display a cute little yellow line around a cell or ship (easily accomplished using a CPen (which I call 'hiliter')), but I get harsh flickering. So, I created CELL, SHIP and BOARD objects. A ship has cells, and so does the board. A ship will have 5 cells, and the board will have 10 by 10 cells (100). Easy enuf to figger out, right?
One last thing: I hope I don't have incomplete lines of code here. If so, just ignore them.

I don't want the flicker!!!
At first, I thot just changing the data in the CELL and SHIP objects would do the trick. But no, that doesn't work! Of course it doesn't - it's Microsoft - he can't make anything easy!!!! Now, I know for a fact the flicker is caused by InvalidateRect(...) - is there a way around this problem, or do I just put up with it?
Anyways, if yer confused, take a look at the DRAW member functions of the CELL and SHIP objects and the OnPaint and OnMouseMove member functions of the 'battleshit' object. Maybe I should just bury my head up my backside and forget this whole endeavor, but I don't relish that idea - I want to be successful; so I beg for your kind assistance.
TY in advance, JamRoll
PS: I don't care what you do to my code. use it, delete it, or serve it for dinner. If it isn't real good, let me know how I can improve it - I'm always trying to create code that is readable, and friendly!

You need to use a memory DC. Keith Rule set the lead with this. There are a few articles here on CP re. memory dc's including: "Further discussions on flicker free drawing" http://www.codeproject.com/vcpp/gdiplus/what_is_a_basename_.asp[^]
Some tips. When you post code use the code and pre buttons in the Formatting bar below the message area. Also the < and > buttons. Show just the code that is of interest, not a huge slab which no body will read.

Ummm... that's an awful lot of code to look through. 
You might want to consider only posting the relevant pieces of code in the future. I'd doubt if anyone would read through that much.

brush.CreateSolidBrush(RGB(0, 0, 200));<br />
<br />
dc.SelectObject(&pen);<br />
dc.SelectObject(&brush);<br />
<br />
dc.Rectangle(0, 0, 400, 552);<br />
<br />
player->draw(&dc);<br />
computer->draw(&dc);<br />
}
and a single CELL draw code:
<br />
void CELL::draw(CPaintDC *pdc) {<br />
if (hilited) <br />
pdc->SelectObject(&hiliter); else<br />
pdc->SelectObject(&pen);<br />
<br />
pdc->SelectObject(&cellBrush);<br />
pdc->Rectangle(rect);<br />
<br />
CRect circle = rect;<br />
circle.left += 5;<br />
circle.top += 5;<br />
circle.right -= 5;<br />
circle.bottom -= 5;<br />
<br />
pdc->SelectObject(&pen);<br />
pdc->SelectObject(&pegBrush);<br />
pdc->Ellipse(circle);<br />
}<br />
a SHIP object draw code:
<br />
void SHIP::draw(CPaintDC *pdc) {<br />
if (hilited)<br />
pdc->SelectObject(&hiliter); else<br />
pdc->SelectObject(&pen);<br />
<br />
if (sunk())<br />
pdc->SelectObject(&sunkBrush); else<br />
pdc->SelectObject(&shipBrush);<br />
<br />
if (size != 5) {<br />
pdc->Rectangle(rect);<br />
} else {<br />
pdc->Rectangle(rect);<br />
<br />
if (hilited)<br />
pdc->FloodFill(location.x + (CELLSIZE / 2), location.y + (CELLSIZE / 2), RGB(0, 255, 255)); else<br />
pdc->FloodFill(location.x + (CELLSIZE / 2), location.y + (CELLSIZE / 2), RGB(0, 0, 0));<br />
<br />
if (vertical) {<br />
} else {<br />
}<br />
}<br />
<br />
pdc->SelectObject(&pegBrush);<br />
for (int c = 0; c < size; c++) {<br />
pdc->SelectObject(&pen);<br />
pdc->SelectObject(&pegBrush);<br />
}<br />
}<br />
and finally the BOARD object draw code:
<br />
void BOARD::draw(CPaintDC *pdc) {<br />
pdc->SelectObject(&pen);<br />
pdc->SelectObject(&boardBrush);<br />
<br />
pdc->Rectangle(rect);<br />
<br />
for (int y = 0; y < size; y++) {<br />
for (int x = 0; x < size; x++) {<br />
cells[x][y].draw(pdc);<br />
}<br />
}<br />
<br />
for (int ship = 0; ship < 5; ship++) {<br />
ships[ship].draw(pdc);<br />
}<br />
<br />
CRect tRect, sRect;<br />
tRect.left = rect.left - (CELLSIZE + CELLSPACING);<br />
tRect.top = rect.top - (CELLSIZE + CELLSPACING);<br />
tRect.right = rect.left + 300;<br />
tRect.bottom = rect.top + CELLSIZE;<br />
sRect = tRect;<br />
sRect.left += 2;<br />
sRect.top += 2;<br />
<br />
pdc->SetTextColor(RGB(0, 0, 0));<br />
pdc->SetBkMode(TRANSPARENT);<br />
pdc->DrawText(_T(title), -1, sRect, DT_SINGLELINE);<br />
pdc->SetTextColor(RGB(255, 255, 0));<br />
pdc->DrawText(_T(title), -1, tRect, DT_SINGLELINE);<br />
}<br />
Yyou will notice some lines of code that read if (hilited) { /*do hilite stuff*/ } else { /*do NON-hilite stuff*/ }. It seems that if I change the hilite value from true to false (or vice-versa) I have to invalidate the area for the change to take affect....this is what is causing the flicker!
One fella sed ..."You need to use a memory DC" - a what???
Perhaps I am just daft...but I did take a course (a 20,000 dollar course at that, altho the course wasn't JUST MFC)...so I should hope i know at least a little of what i am doing...hehe; the teacher was useless at helping me correct the flicker - told us (the whole class) to figger it out ourselves!!! 
anyways, thanx for yer help guys! It really is appreciated, and please please forgive my previous LONG post... 
ciao for now! JamRoll...

Using a memory device context basically means that you do all your drawing to a bitmap held in memory, then at the end draw it to the screen with a BitBlt() call. Then whenever you redraw the window, don't erase anything (override OnEraseBkgnd() and do nothing) and just draw the new image over the top. That will give no flicker.

I see...can ya point me in the direction of a simple example of how to use a memDC? I found a thingy called CMemDC.h, but that's pretty intense stuff...i'm still mainly a beginner here...
ty again.

Using Keith's CMemDC class is much easier than doing it manually... That's the easiest you're gonna get
