Hi
I need some help here,
I have some dlls compiled from Visual C++ which I would like to be exposed as Web Services using ASP.
On a system running windows xp.
I have read up on this article :
http://support.microsoft.com/defaul...kb;en-us;239445
1)But this would mean I would have to rewrite majority of code that wasnt written by me (a package handed down to me),
It would be much too time consuming. Is there a way I could using the dlls "as is"?
2)If I have to do it this way, how do I define a method that returns a value?
3)I also tried to create a package in COM+ using the Component Services. However I had trouble linking up all the required files.
(is this a correct method anyway?)
http://support.microsoft.com/kb/223406/en-us
I cannot find any articles that detail the process, even a link to something I should read up on would be greatly appreciated.
Thank you.
Eugene

Can someone help me with my program. I am doing a shortest path program in C++ MS Visual Studio.net using MFC and I need to display the different points(circles with the number on them). I have placed a group box on my dialog box and i want to place the points on the group box. So far I have three edit control boxes. One for point number, and the other two are for x and y coordinates. I have also placed a button to add the point once the data is set in the edit control boxes. Can someone help me display the points please. Also if there is an easier way to display the points can you let me know. I have tried to understand the article on Dijkstra's Algorithm that is posted here at this website but I cant understand to much

i can used LCD but i can not use "printf" how use it??

You will probably have to write your own.
If you have a library that can write strings to the display, then you can use sprintf(...) to format a string then send that to the display.
Good Luck!

Hello all. I'm using Windows' GetFileSize function to get the file size:
<br />
HANDLE hFile = 0;<br />
DWORD dwLowSize = 0;<br />
DWORD dwHighSize = 0;<br />
QWORD qwTotSize = 0;
<br />
hFile = CreateFile(m_pFileInfo->szFileName, GENERIC_READ, FILE_SHARE_READ,<br />
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);<br />
dwLowSize = GetFileSize(hFile, &dwHighSize);<br />
CloseHandle(hFile);<br />
Now, I goy dwLowSize and dwHighSize. How can I get the __int64 value of the both? How should I combine dwLowSize and dwHighSize in order to get the complete size of the file?
Thanks.
KK.

im thinking you could do this, (looked at MAKELONG, MAKEWORD macros)
#define MAKEQWORD(a, b) ((QWORD)(((DWORD)(a)) | ((QWORD)((DWORD)(b))) << 32))
qwTotSize = MAKEQWORD( dwLowSize, dwHighSize );

If you are processing a lot of data, Sleep is about your only choice. You must chose between fast data processing and program performace. It is all a balancing act; a single CPU can only do so much and every but wants a slice of its time. The best you can do is to run profiling to see where the bottle necks are (slow code) and optimize those functions that are taking to long to do there job.
Good Luck!

What exacly you want to do ?
why would you want to use Sleep ? it will stop the loop from looping ( and suspend the application ).
If the software loops, and is taking 100% of the CPU, it is because the OS decided that nothing else important needs the CPU;
I'm not sure what you mean by "minmal CPU performance" ? even a low priority process will be put to work when nothing else happens.

 well if the processing that u want to is not that important ,give ur code in the OnIdle() function.....
maybe that could help.....

set a timer to perform your task at a time interval without using CPU when your program's not running (active loops are bad for that).

Hi,
Can anybody help me with the following:
I have a Dialog with CRichEditCtrl. When I right-click the mouse inside the CRichEditCtrl a popup menu appears with one menu item called "Select Text". When the "Select Text" is clicked I want to highlight the text before the mouse cursor position.
I have created the popup menu that appears when the right mouse button is clicked. How can I highlight the text? 
Thanks very much,

CRichEditCtrl::GetSel() EM_EXGETSEL
CRichEditCtrl::SetSel() EM_EXSETSEL
To select all the text before the current caret positon:
GetSel(nStartChar, nEndChar);
SetSel(0, nEndChar);
Should do it!

Hi i've come across this before and had to re-create the project to get it to work.
I've created a new win32 dll project with VC++6. (No MFC)
It's a simple utils dll with just functions, no DLLMain, Attach etc..
Upon build of the app, no .lib file is being created.
I am exporting a function.
(__declspec(dllexport) int logEvent(char* logFile,char* event,bool bLog);)
Can someone tell me why it isn't producing the .lib file.?
Can i use 'lib' to force this creation?
thanks in advance
Carl
below is the linker options from VS:
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib<br> odbccp32.lib /nologo /dll /incremental:yes /pdb:"Debug/assemblyUtils.pdb" /debug /machine:I386 /out:"Debug/assemblyUtils.dll" /implib:"Debug/assemblyUtils.lib" /pdbtype:sept

Answer:
Well it seems i didn't add the header file in the cpp to the exported declaration of the function. Even though it compiled, nothing was being exported.
added the header and bobs your aunty betty!
thanks to myself

I have a treelist which I want to add some icons to. I am confused by this but I have seen some code which uses a width of 19 and height of 13 for its icons. The icons I want to use are 16x16 and are multi-color. The icon is a file which contains a 256 color image and a 16.8M color image. There are also 24x24, 32x32 and 48x48 sizes.
What do I set the treelist icon size to for the best? Is the standard font what determines what height I should use? I suppose the width depends on the icons I want to use but if I can use a height of 16 I might as well then use a width of 16.
Are there any articles which explain this clearly?

I have not seen any articles explaining this. I have been able to use any size icon, and 32bit color. Probably 256px wide is a reasonable limit. The limits are built into the imagelist you use, not the tree control itself.
