I had a similar issue. After installing the VS2005 Pro as well as the VS2005 C++ express, I got a package load error each time I started VS2005 pro OR the vs2005 C++ express editon. I uninstalled and reinstalled several times and got the same result. I also tried using the uninstall exectutable from Microsoft to no avail.
Finally I took the following steps:
1. uninstalled EVERYTHING that had to do with Visual Studio, and .NET components (2.0, 1.1, 1.0), SQL Server and MSDN, MSXML. I mean everything. I followed the uninstall directions given in the dialog after uninstalling Visual Studio and removed/uninstalled the items in the order specified.
2. Then I went to the WINDOWS\assembly directory and deleted EVERYTHING under that directory.
3. I went to "Program Files" directory and deleted everything that had to do with Visual Studio and .NET (2.0, 1.1, 1.0) and SQL Server and MSDN.
4. I also went to the following directories and deleted everything and all directories that had to Visual Studio, SQL Server, MSDN and .NET (2.0, 1.1, 1.0)
"Documents and Settings\<username>\Application Data\Microsoft"
"Documents and Settings\<username>\Local Settings\Application Data\assembly"
"Documents and Settings\<username>\Local Settings\Application Data\Microsoft"
5. Finally I deleted all tempory files in all temporary directories and cleared the internet cache and temporary files using IE
6. I also went to "My Documents" and deleted the Visual Studio stuff there.
After all that I reinstalled VS2005 Pro and VS2005 C++ express and I no longer get the errors.

I looked for articles on this before asking a question on this
forum. But...
How can I add a local hotkey to an application only? I want to
add the hotkey CTRL + A and I want it to popup a dialog box.
Anyone have any sample code, instructions, or a simple demo
project?
Please, any response any one can give me will be greatly
appreciated.

I assume you are talking about an accelerator. If so, you first need to add an entry to the accelerator table. Per MSDN:
1) Select the new-item box at the end of the list.
2) Type the key you want to use as an accelerator. The Accel Properties page appears, with the focus in the Key box.
3) Select an ID from the drop-down list in the ID box.
4) Change the modifier and type, if necessary. The modifier specifies whether the key you chose is a combination formed with CTRL, ALT, or SHIFT. The type indicates whether the key is an ASCII or a virtual key value.
5) Press ENTER.
You'll then need to call LoadAccelerators() to load the table. In your message pump, use TranslateAccelerator().

Hi All
I am using "ISO ANSI C++",and i am beginner in C++, and i am working now in console applications , and i want to know if is there any way to control data entry in "ISO ANSI C++"
for example
close all the keyboard except the numerical keys
so user can only add numbers
thx all

Can you use getchar() for this?

Hi all,
I am Visual C++ junior in the begginer level. I encounter the problem when using some functions built in c file (such as printf("..."); ....) for my project GUI Visual C++ MFC.
ex: when button is clicked then function prinf("..") will be called. But Errors occur when I build solution.
void CButtonTestDlg::OnBnClickedButton1()
{
printf("test printf used in GUI MFC"); // error here.
}
How can I reuse all functions in c file supplied for specific device by manufacture. Thanks

Well, you cannot use printf because there is no standard out in a Win32-based program. You can either use message boxes or change a static text item. You can start by replacing that printf statement with
MessageBox(_T("message box text in GUI MFC"), _T("test"), MB_OK);
|

Ah, it helps me a bit. Thank you.
But I have a long list of functions and few external c files.
For example:
my dlgfile.cpp in GUI has
void CButtonTestDlg::OnBnClickedButton()
{int num1 = 5; int num2 = 10; int result; int error =1;
result = sum(num1, num2); //error unresolve external symbol "int .."
result = extern sum(num1, num2); //remove above lin , extern error
//extern displayError(error, result); //erro internal compile
displayError(error, result); //error unresolve external symbol "int .."
}
my ExtFile.c has
int sum(int num1, int num2)
{int SUM;
SUM = num1 + num2;
return SUM;
}
void displayError(int error, int result)
{ printf(sum %d \n"result);
switch (error)
{case 1: printf("error 1"); break;
case 2: printf("error 2"); break;
default: printf("error unknown"); break;
}
}
... other function()
Any ideas thanks.

Again, there is no standard out, you can't just printf characters to the console, there is no console. You can change displayError to look like this:
void displayError (int error, int result) {<br />
CString szMsg;<br />
switch (error) {<br />
case 1: { szMsg.Format ("sum %d\nerror 1", result); } break;<br />
case 2: { szMsg.Format ("sum %d\nerror 2", result); } break;<br />
default: { szMsg.Format ("sum %d\nunknown error", result); } break;<br />
}<br />
MessageBox ((LPCTSTR) szMsg, _T("Error"), MB_ICONSTOP);<br />
}
That creates a CString called szMsg. CString's have a member function called Format which you can fill the CString just as if you're using printf/sprintf. Depending on the error, it fills szMsg with the text you want. At the end, it calls MessageBox to display the text. I like to cast my CString's to regular null-terminated strings. The next item is the caption, or what's displayed in the title of the box. The last item is the icon or button style to use, I selected it to just show the traffic "STOP" sign. That will do just what you need.

hi everyone i'm new here and in programming too 
so i have a question.
i assign char to a text field variable and on screen appear the text which i'd like to appear but after this text there are some symbols.
i think my function which converts int to char could cause this ...
here is my function :
char* CPro01Dlg::Convert(int *y, int num)
{
int i, a, b, k=0;
char *text;
text = new char [2*num];
for(i=0;i<num;i++) {
="" if(y[i]="">=0 && y[i]<10) { text[k]=y[i]+48; k++; }
else if(y[i]>=10) { a = y[i]/10; text[k]=a+48; k++; b=y[i]-a*10; text[k]=b+48; }
}
return text;
}
each y[i] is from 0 to 26

What exactly is the Convert() method supposed to do? If it is simply converting from int to char, you've got way too much code. It's not that complicated.

I am not sure what your code is realy supposed to be doing. But you can get rid of the extra simbols by simply appending a '\0' character to the end of 'text'.
I decided to rewrite your code so it makes a little more since:
char* CPro01Dlg::Convert(int *y, int num)
{
int i, a, b;
char *text;
text = new char [num+1];
for(i=0; i<num; ++i)
{
if( y[i] >= 10 )
{
a = y[i] / 10;
text[i] = a + 48;
b = y[i] - a * 10;
text[i] = b + 48;
}
else if( y[i] >= 0 )
text[i] = y[i] + 48;
}
test[i] = '\0';
return text;
}
INTP
Every thing is relative...

thanks a lot. . .
i only needed '\0' at the end of the char.

I need help on the coding for this project. Is there any examples or coding for this program...... Write a program in C++ to simulate the performance of the SSTF and the C-LOOK disk scheduling algorithms shown in class. We assume the disk system supports track numbers ranging from 0 (the outermost track) to 49 (the innermost track).
The following shows a scenario of running the program, where user’s inputs are in boldface.
>smi3456p3 {an executable program}
please enter a sequence of track numbers:4 40 11 35 7 14
where is the current position of the arm?15
what do you want to do?
1 = SSTF
2 = C-LOOK
3 = quit
1
the history of arm movement is: 15, 14, 11, 7, 4, 35, 40
what do you want to do?
1 = SSTF
2 = C-LOOK
3 = quit
2
what is the direction the arm is currently moving?
1 = toward the innermost track (i.e. 0)
2 = toward the outermost track (i.e. 49)
2
the history of arm movement is: 15, 35, 40, 4, 7, 11, 14
what do you want to do?
1 = SSTF
2 = C-LOOK
3 = quit

I don't think many people here want to do your homework for you. The best advice I can give you is to write down how to solve the problem on paper, then realize what you did to solve the problem and simulate that when you write code. I've studied the disk scheduling algorithms myself, they aren't too difficult and I think you can do it yourself.

Why does this code compile? It crashes at runtime
int test(LPCWSTR p)
{
return wcslen(p);
}
int test2()
{
return test(L'');
}
.
thanks!

Are there any warnings from the compiler?
It's tough to tell from the code listed but it looks like you are casting a character to a string pointer. It's pretty unlikely that the string is going to be null terminated. That's what I'd be looking at.

I am not casting, L is the notation to indicate its a unicode string. To me this is a compiler bug. More over the following code gives an error when compiled:
<br />
int test3(LPCSTR p)<br />
{<br />
return strlen(p);<br />
}<br />
<br />
int test4()<br />
{<br />
return test3('');<br />
}<br />
<br />
I am using VS6. Can someone check if this compiles on VS2003 too?
thanks!

It compiles because it's a valid code.
why it crashes ? well, p is NULL so that why it crashes.
I assume the L macro ( is it a macro or a MS specific keyword ? ) cannot expand a single char into a wide char string.
are you certain you're not wanting to do this instead ?
int test2()
{
return test(L"");
}

You are right, I had typed single quotes by mistake, and that proved costly. If only the compiler had caught it life would have been little simpler.
I dont know what L'' resolves to? There can be an empty string, but empty character doesnt make any sense. It is not clear how this compiler thinks.
thanks!

First, the L prefix causes the complier to treat the following constant string or character as a wide-version. So, L"Test" creates a wide string, and L'3' yields a wide character.
The empty character constant '' yields a value of zero. Since the function was expecting a pointer, and a value of zero can be used for a pointer (it is the same as NULL in C++), that is what happened and why the code compiled correctly.
Peace!
