dear Joaquín M López Muñoz'
Thanks a lot ..
But my doubt is that will the PATH for environment variables be same in all the WIndows OS starting from Windows 98????
If there is a API ,it would be much better ...

See SetEnvironmentVariable()/GetEnvironmentVariable() in the docs. Win95 and later.

This is the functin I'm working with:
void CJobQueueSimulatorView::LoadSkills()<br />
{ <br />
<br />
int numItems = m_skills.GetCount();<br />
<br />
for(int k = 0; k < numItems; k++)<br />
{<br />
m_skills.DeleteString(0);<br />
}<br />
<br />
char next[25];<br />
<br />
fstream fin(strCurrType + "_skills.txt", ios::in);<br />
<br />
if(!fin)<br />
{<br />
MessageBox("Could not open skills file!", "File Error", MB_ICONEXCLAMATION);<br />
}<br />
else<br />
while(fin >> next)<br />
m_skills.AddString(next);<br />
<br />
fin.close();<br />
}
What I would like to do is prepend a letter to each line I read from my text file. This would give me an I.D. that I can associate with each "skill". m_skills is a list box control variable. I don't want the letter code to be saved in the text file. I would like it to be assigned as the lines are taken from file and put into the list box. This would prevent users from assigning skills the same "I.D". Also, later when they add skills to the list, it would automatically assign an "I.D" I'm thinking the way to do it is with ASCII but I'm dumb and don't know how to do it. Anyone have a good idea of how to do it? (Sorry for the sloppy formnatting above. Things didn't copy over that well)

strcat() example from MSDN:
<br />
<br />
#include <string.h><br />
#include <stdio.h><br />
<br />
void main( void )<br />
{<br />
char string[80];<br />
strcpy( string, "Hello world from " );<br />
strcat( string, "strcpy " );<br />
strcat( string, "and " );<br />
strcat( string, "strcat!" );<br />
printf( "String = %s\n", string );<br />
}
Output:
String = Hello world from strcpy and strcat!

char next[25];
CString str;
...
while(fin >> next)
{
str = some_unique_identifier + next;
m_skills.AddString(str);
}

I am using WinExec("C:\\logfile.txt",SW_SHOW) to open my file in a notepad on pressing a certain button but the file is not opened in the notepad. Infact nothing is happening when I press the button.
I am using the same code of line WinExec("Notepad.exe,SW_SHOW") to open the notepad and it is working properly there. Plz give me its solution, by just giving the path of our file, it could open in a notepad.
thanx
Reply me soon

According to MSDN, the first parameter of WinExec is "Pointer to a null-terminated character string that contains the command line (file name plus optional parameters) for the application to be executed". In other words, first parameter must include name of program you want to execute. WinExec is not shell-oriented, i.e., it does not "associate" file types with applications. What you want is ShellExecute, which is shell-oriented:
ShellExecute(NULL, "open", "C:\\logfile.txt", NULL, NULL, SW_SHOW);
Best wishes,
Hans

Did you try WinExec("Notepad.exe C:\\logfile.txt", SW_SHOW)? WinExec("C:\\logfile.txt", SW_SHOW) tries to execute logfile.txt which is not an executable file.

Well, thank you. Instead of SW_SHOW use SW_SHOWMAXIMIZED.

How can I convert twips to pixels?
|
|
|
|
|
Try this:
#twips = is width
#pixels = MulDiv(#twips, GetDeviceCaps(hDC, LOGPIXELSX), 1440)
#twips = is height
#pixels = MulDiv(#twips, GetDeviceCaps(hDC, LOGPIXELSY), 1440)

Thank you so much Ernest. This is what I was looking for. I knew that there were 1440 twips per inch or 567 twips per cm but I just couldn't figure out how to get the number of pixels per inch. Thank you.

GetDeviceCaps() LOGPIXELSX LOGPIXELSY
for a screen these will usually be hardcoded to 72 dpi as windows has no real knowledge of the physical size of the display

Hello all
Plz , I search a code of a GUI(MFC) same in this URL : http://www-ic2.univ-mans.fr/~lemeunie/these/node75.html#fig-interface-ami1
(Figure 4.3: Interface de AMI1).
Thanks very much

So what's your question? By the way, the URL you provided is invalid.

Well, it's a dialog box with the following controls:
a listbox
a static label
an edit box
four push buttons
|
|
|
|
|
Do you know any code or tutorial in net?
|
|
|
|
|
Yes, the Internet is littered with code examples. What specifically do you want to do?
|
|
|
|
|
To begin,
I want make a same Gui in the picture:
When i write any text in the an edit box i'll see this in the a listbox .
http://www-ic2.univ-lemans.fr/~lemeunie/these/img186.gif
|
|
|
|

Well, assuming one of the four buttons is an Add button, you can have something like:
BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
ON_BN_CLICKED(IDC_ADD, OnAdd)
END_MESSAGE_MAP()
void CMyDialog::OnAdd( void )
{
CString strText;
m_edit.GetWindowText(strText);
m_listbox.AddString(strText);
}

I am a self-learning novice learning win32asm. It is possible to create a dialog box as the main window without using window class. My question is weather it is possible to create a dialog box as a main window in VC++ using SDK? Can any body give me a code in VC++ without using registered window class?
Thanks

Yes, use CreateDialogParam for modal or CreateDialog for modeless! First message to wait for is WM_INITDIALOG. Good luck!
