Okay first, I have an executable the loads several DLLs. One of these DLLs needs to create a window and set an openGL context. A second DLL, which gets placed in its own thread executes functions on the first DLL. The initial problem I had was that the window was being created upon loading of the first DLL, and when the second DLL called functions on it from it's own thread, the openGL context would not be valid. I fixed this by making sure the window was created by the second DLLs worker thread that calls all of its functions.
So now, I can verify that all of my openGL calls are not failing, the problem though is that nothing is happening in the window itself. Right after the window is created it appears to hang. The cursor changes over it and it is no longer selectable. I can verify that the windows message proc is being called correctly and it does get to WM_CREATE. I can also verify that the program itself is not hanging as the calls are still being made.
The only thing I can think of as the problem is that when the window is created it is launching it's own additional thread, and I am subsequently trying to make my GL calls within the wrong thread. First, does this sound like the problem, and if it is, is there a way to make the window launch within the same thread that created it? I have made sure that the HINSTANCE that is passed into CreateWindowEx is that of the DLL.
I hope this makes sense as it is a little long winded. Any help is appreciated.
Thanks,
Dustin

How to create and maintain HTML file?
Many applications use HTML as their log file. Many application output data to HTML too.
I also hope to use HTML file as my application's log file. I hope to use it to provide more information to uses by HTML file.
So I have to create HTML file for log file. I have to read old HTML file and update information in the HTML file too.
Is there one HTML library that can make it easy to write and read HTML file? Can it make it easy to parse the information in HTML file?

I'd recommend to use XML files for logging. There are tons of libraries to modify XML files. You can then use XSL to convert it into a HTML file. If you link the XML file to the XSL file then loading the XML file with a browser automatically shows the desired HTML page. I learned everything form www.w3schools.com/[^].
Kind regards

Hi there,
I would like to write a program that converts a small text file into a picture file, probably a .jpg. I would also like the optio of adding smaller .jpg files to the larger .jpg file containg the text.
I just need to know the best way of doing this in C/C++/MFC. I need this to work in a windows environment though Linux compatability would be an added bonus.
When this project is complete I will add it to code project as my first post.
Thanks for looking!
Tony

Can you explain this a little better ? what is the input text ?
anyway, a non-portable solution :
You can use CDC::TextOut or CDC::DrawText to draw to a device context.
After that, you can use CBitmap::CreateCompatibleBitmap to create a bitmap from the device context; and after that, use CImage (from GDI+) to "export" the bitmap object to jpg or bitmap, or whatever format CImage supports.

I just need a program that opens small .txt files created with notepad and also small .jpg pictures. The program then needs to combine the text and pictures into one larger picture file probably a .jpg.
Thanks again!

Yeah but out of context that doesn't mean anything... What are you trying to do exactly ? Sould the text be written on the picture ? If yes, where, and how, and with which font, ...
Do you realize that your question doesn't make a lot of sense ?
You have to explain what you mean by combining text and picture.

Sorry if my original question was a bit vague. It's been quite a while since I've done any C/C++/MFC programming, in fact VC6. I just need to be pointed in the right direction.
Let me rephrase my question. I have been thinking that instead of converting .txt files and .jpg files into a larger .jpg file, it would be easier if I could convert a single .htm file (obviously containg text and .jpg) into a single .jpg file. Where do I start and what do I need to consider, is this much more difficult than I thought?
Regards
Tony

It might be more difficult than you thought or perhaps you are not quite sure of what you are trying to do. If you are going to combine a text file with a jpg you will first need to be able to read your text file and your jpg.
I suggest you use google or the CodeProject search facility to find out how to read jpgs (reading a text file should be trivial) and display them.
From there you need to decide what you want to do with your text - put it over the picture like a watermark? Place it above or below like a title? Do you need to be able to move the text around the screen to place it? Are different fonts required? What facilities do you want to be able to add, move, change font/colour/size? Menus, toolbars?
When you have thought about all this and how it might go together then you need to think more about what you then want to do save it as a jpg? Other formats allowed? Save As?
Let us know how you get on - if you have any (more specific) questions I'm sure you'll be helped here by someone!

You could download Imagemagick, that has all the things you asked for (and much much more), compatible with linux also... It has a simple commandline interface that can be called from yoyr program...

hi all,
i have declared a character pointer like this:
char *cHeaderInfo = new char[dwSize + 28 + dwSize1 ];
but while deleting it i am getting assertion failed on this line:
if(cHeaderInfo)
{
delete []cHeaderInfo;
cHeaderInfo=0;
}
it is working fine in 90% cases but failing sometimes, but i am not sure why...so please help me out of this.
Thanks A Ton

What does the assertion say?
You're probably storing something in cHeaderInfo that is bigger than dwSize + 28 + dwSize1.

You should consider using the safe string functions like _tcscpy_s and other C runtime functions that end with _s. Or you must use safe string APIs like StringCchCopy.

Keep in mind that you may have simply masked the problem rather than actually solved it. Find the code that writes to that variable to make sure it is indeed big enough.

I suspect you've forgotten to add "+1" for the null terminator - looking at your code, it looks like you've added the maximum sizes of constituent strings, but not the '0' at the end.
I would suggest you think about using a string class (std::string or CString) rather than char arrays wherever possible - that way you don't need to worry about managing memory like this.

here it is the C code , it prints the base filename
I want to modify it to print the following
/work1/data/xxxx/yyy/
const char * path = "/work1/data/xxxx/yyy/file_name.txt";
const char * filename; filename = path+strlen(path);
while (filename != path && *(filename) != '/')
filename--;
if ( filename != path)
filename++;
cout << filename;
|
|
|
|
|
|
it didn't work
I need to print the path without the baseile name
|
|
|
|

this logic worked for me perfectly.
const char * path = "/work1/data/xxxx/yyy/file_name.txt";
char path1[256];
strcpy(path1,path);
cout << path <<"\n";
int l=strlen(path);
for(int i=l;i>0;i--)
{
if(path1[i]=='/')
{
path1[i]='\0';
break;
}
}
cout << path1<<"\n";
the output is as you desired.

sorry,
it didn't work
why?
look at the way you are using strcpy() function

You don't need to parse. Use SHString apis.
