Thanks.
You made a very good point. First off, I made a change to the display algorithm. This new algorithm concatenate all lines into one string and then display one string only.
New algorithm:
-----
currentData = pDoc->GetOneLine(pos++);
rE.SetWindowText(currentData);
if (pDoc->GetLineCount() > 1)
{
newData.Format("%s\r\n%s", static_cast<lpctstr>(currentData), pDoc->GetOneLine(pos++));
for (size_t i = 2; i < pDoc->GetLineCount(); ++i)
{
newData += "\r\n";
newData += pDoc->GetOneLine(pos++);
}
rE.SetWindowText(static_cast<lpctstr>(newData));
}
-----
Okay. The reason I chose a linked list was because the program needs to remove one or more nodes at any section of the list. Vector does not have the feature of direct insertion and removal anywhere in the data structure. I have not consider a map. I will definitely consider it now that you have brought it up.

I created a class based on CFormView and written a WM_SIZE handler.
When I create form size smaller then Dialog in resourse, controls are resizing correctly, but scrollbars appears...
When I sroll scrollbars there are blank space, and srollable area always have same size as dialog resource...
You can see my problem here: http://www.mediagate.ru/title.gif
any ideas?
Anything that can go wrong will go wrong.

You can change the size of a form view area. At the end of the OnSize function call
SetScaleToFitSize(cx, cy) ;
This will stop the scroll bars from appearing.

Thank you for this solution, all works as I need, but sometime, when cy==0 I have Debug Assertion in wingdi.cpp on following line (465):
VERIFY(::SetWindowExtEx(m_hAttribDC, x, y, &size));
I finded this solution:
SIZE csize;
csize.cx=cx;
csize.cy=cy==0?1:cy;
SetScaleToFitSize(csize);
may be there are another ways to correct this problem?

Does anyone know how to get a handle to the icon of a running exe?
Thanks
|
|
|
|

Are you talking about while your program is running or just get the icon from another application?
If you simply need the icon from another application, you can load the exe of that application into Dev Studio and extract the icon.
If you need the icon while your program is running that will be a little more difficult. What you need to do is get the top level window of that application, and call GetClassInfo. This will give you a WNDCLASS structure that will allow you to get the HICON.

I can't seem to get GetClassInfo to work with an HINSTANCE of an external module. Does this function only work with the HINSTANCE of the current process?

Hi,
I need to be able to perform screen captures at a high frame rate. So far, I get reasonable performance when I use the BitBlt function to copy the bitmap from the window DC to the memory DC. The problem lies in GetDIBits...this function is incredibly slow and adds considerable bottleneck to the system.
The thing is, I need to be able to use each of the captures in real time. Converting them to DIBs later isn't an option.
Is there a faster option than to use BitBlt/GetDIBits to capture each screen? How about comparing each successive bitmap and using only the deltas...can this be done quickly?
Thanks!

Yes, copy the screen to a DC that contains a DIBSection - you then have a pointer to the bits at all times.

The main problem in your slowness extends from the fact that the transfer of the bits from video memory to system memory is very slow. I was able to speed up the screen capture with DirectX, however I was only able to shave off about 200 milliseconds off of a 1.3 second screen capture process.
You are not going to get much faster with the technique that you are using. You may want to look at how NetMeeting does this. They create a second display driver that is able to capture the updates to the screen before they happen, and log the deltas in the bitmap. Then operate only on the deltas.
There is a function that will allow you to detect the rectangle of the changes for a DC, but it only works on memory DCs, and I cannot remember the name of it right now.

Why is it required to place a scope resolution operator when writing code out for class functions, and why does it cause a syntax error?

it's necessary because that's how the compiler knows which class to attach the code to, so to speak. without it, you'd need to have unique names for every function in every class - which makes inheritance pretty much impossible.

As Chris has already said, it lets the compiler associate a function's implementation with a class. My point is that you can separate a large class (i.e. one with many functions) into different files. Also (not recommended), the same .cpp file can contain functions of more than one class.

How must i set the parameters for the function FindFirstFile() if i want to get the shared files which are located at a remote machine!!
I have tried FindFirstFile("\\\\machnine\\*",&data);
and FindFirstFile("\\\\machnine\\",&data); and
FindFirstFile("\\\\machnine",&data);
and much more else but i have always got the error code ERROR_INVALID_NAME!!
Please help me!!!

If you are using a UNC name it must be fully qualified.
FindFirstFile("\\\\machnine\\share_name\\*.*",&data);

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Yes! I wondered the same thing after installing VS.NET on my new HDD and watching it kill all my old code. Not wanting to distribute the version 7 .DLLs on my webpage for the next version of my program anyway, I installed VC6 and it's co-existing perfectly, much to my surprise actually. So I can pick up where I left off without having to fix a million broken things, and I can still use ClassWizard.

I need to create an visio-like userinterface, (especially resizing and moving objects) Does windows provide any scaling or moving functions which can be used ?

GDI+ does.

I deleted to source files from my project directory thinking that would remove them from the project. Now the darn thing won't compile. I keep getting "fatal error C1083: Cannot open source file: 'D:\Projects\My Proj\IntDlg.cpp': No such file or directory
What do I do now!?! 
Why not throw away a dime?

Using the File View portion of the Workspace toolbar, simply highlight the offending source files, and hit the Delete key. This will remove the files from your project, and they will no longer be compiled. Hope this helps.

D'uh! I can't believe I forgot that! Oh well. This is my first day programming VC++ again for a few months. Thanks for the help.
