I recently switched from Bloodshed to Visual in order to use FLTK, but I'm having trouble with just compiling/running a simple file. I know that a file has to be in a project for it to be compiled (what is the purpose of this by the way?), but even after I figured that out I'm still having issues. The errors given aren't very clear either :/

Something as simple as this doesn't compile.

#include "std_lib_facilities.h"

int main()
{
  cout << "This creates an error." << endl;
  keep_window_open();
}

1>. \Debug\Exercises.exe.intermediate.manifest : general error c1010070: Failed to load and parse the manifest. The system cannot find the file specified.

My guess would be that this is because it doesn't recognize the std_lib_facilities header, even though it's in my project folder. How can I get the IDE to recognize the header?

Well it doesn't generate the error message anymore, but when I try to compile it just says 1 up to date rather than 1 succeeded. When I try to run it I get a message saying that it can't find the file path specified.

Ok, and?

And what? What information do you need.

Small details like where does the message come from, and what file is it referring to?

Okay if I try to run it, the "cannot find file path specified" is a pop up message.

The file path is C:\Users\Alex\Documents\Visual Studio 2008\Projects\Exercises\Exercises\Debug\Exercises.exe

Now that I look at it the file path isn't correct.

I'm learning from a book, and since I realized that in Visual Studio you can't compile a file without it being in a project, I figured I would just put all of my files into one project.

Basically all I did was create an empty console application project called exercises, and copy and pasted all of my files into it.

Obviously I'm doing something wrong. (Seems odd that they wouldn't just implement a simple compile and run for a single file.) I want to just delete the project and start from scratch to set up everything correctly.

If you need any more info let me know, otherwise I don't know what to do.

Sure you can, just don't confuse the IDE with the actual compiler. Here are the compiler options.

I decided to just switch back to Bloodshed. Found out they have a package manager to manage the FLTK.

I am emulating mobile in windows platform.. so I have two text box emulating 2 lines of LCD of mobile.

Max number of character that i can store in memory can be 50 per line, but the only 20 characters can be displayed in LCD(text box) at any point of time.

I have to take of scrolling left, scrolling right, including insertion and deletion of character in LCD(text box)

I know i have to take of Cursor position, and possibly have MasterBuffer which will contain the 50 characters and TemporaryBuffer which shall contain 20 characters to display.

I can work out a logic to take care of insertion, deletion etc.

But before i start doing my own logic, i wish to know is there any algorithm defined for it already as or any library available or any kind of class.. or code snippet.. i dont want to start from ground zero if it is already something is available.. as i felt text editing in mobile is common..

Let me know if you want more info..

Advance thanks on your reply!

Read function is not working properly..

hi all,

i am making my unicode supporting one. i have to read content from the notepad file..

i am using Read(cstring x,uint ncount) function..(MFC function..)

i have chinese content in my file now.. if i try to read the file, the max. number of bytesread is 1268 only.. y is it so??

i tested with various files too.. but it reading upto 1268 characters... can anyone shed some light on this one??

whereas , i have a text file which contains only english characters but saved in unicode format was read successfully.. the file size was 142,266 bytes and it read completely..

its surprising me that its reading only 1268 bytes when i have chinese characters in my file..

pls tell me the approach how to solve this issue..

Thanks,
Rakesh.

I have this strange problem.. I made a program in VC++ which makes LAN(Language) file from database.. I had this "Simplified Chinese" database and i made some 10-12 LAN files from it.. Now when i try to read and write LAN files entries in my project, it shows mixture of "???? and some right data"... So i again did the read/write operation using Unicode, and all went well...

Now the project is real big and i was only making LAN file from database, Other application which are uncountable uses my LAN file to read and write data into the project window and they aren't using Unicode to read or write, so obviously the output comes as mixture of "???? and some right data"...

So it's vivid that if i change all the application to read/write using Unicode only then it will show right data, But problem is that i can't change anything as it was written a long time back and a lot depend on that coding... So is there any way i can still do this thing.

P.S
No problem is coming when i use "Chinese(Traditional), Portuguese, Italian, German etc" databases... I guess some of simplified Chinese character are not detected if we don't use Unicode method..

Thanks all Smile | :)

Guys,I know this question has been asked ad-nausem, but I have the exact opposite problem. My release build works fine, my debug build does not !

I have an application that starts a whole lot of threads for processing multiple feeds of video and audio. In my release build all threads start successfully, but in my debug build some threads fail to start, AfxBeginThread returns NULL and GetLastError return 0.

I am assuming that some or other resource has to be increased for my debug build to work. I've increased my stack sizes (in project properties) to 10x what it was without making a difference. What other properties/resources can I try to set for my debug build to work ? Any other reason why some of my threads won't start in debug build ?

Hm, I had that problem two weeks ago.
Solution was simple in my case (well, after almost despairing), in project properties the debug and release version had provided different arguments to the main function.

Hi Souldrift,

Where in the project properties would I see that ? I looked through all the settings, but could not quite see where you can pass arguments to main.

Well, the problem here is, I got the german version. But I try to translate.

When I open the project properties there´s on the left side a box where I can find

* General properties
  * Framework etc ...
* Configuration properties
  * General
  * Debugging  <--
  * C/C++
  * etc.

You can find it under Configuration properties->Debugging. In the right window you can now see the arguments in the second line.

But then again, if you don´t know this property, then you most like didn´t enter anything in into it, anyway. You can use this to 'simulate' (argc, argv) arguments of a main function .. if your project has one. And as for everything else, you can do this seperately for Release and Debug version.
