Quick Question,
Anyone have a *good* way of blocking a UI thread until a child-process finishes executing?
Whats commonly used?
ps: This weather sucks.
|
|
|
|
|
WaitForSingleObject(hProcess, INFINITE); might be what you want.
|
|
|
|
|
If you mean completely block the UI thread, then just do a WaitForSingleObject(...,INFINITE) on the child process handle.

If you said Pause the Thread...
If that is your question, you need to Use SuspendThread and ResumeThread functions...;)

Is it possible to create a CMap which maps CStrings vs. ints? that is
CMap <cstring, cstring&,="" int,="" int&=""> map;
I switched around the keys, and it works. I thought you can map just about anything against anything. Any ideas?
c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(129) : error C2440: 'type cast' : cannot convert from 'class CString' to 'unsigned long'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(1324) : see reference to function template instantiation 'unsigned int __stdcall HashKey(class CString &)' being compiled

You got to overload the template function HashKey to work for CStrings. Here's an example extracted from http://www.codeguru.com/cpp_mfc/excoll.shtml:
template<> inline UINT AFXAPI HashKey (CString& strKey)
{
LPCSTR key = strKey;
UINT nHash = 0;
while (*key)
nHash = (nHash<<5) + nHash + *key++;
return nHash;
}

yes, you can do this, but you have to provide the hash function.

or... use std::map . it's better and will gain you STL-credibility among your fellow programmers.

MFC containers suck. Use std::map and you won't have any trouble.

Could you be more specific please?
Is it that they are not fast enough?

No support for algorithms, no easy compatibility with other containers, not standard, written only as a stopgap prior to STL, never intended to replace it.

Can someone share a sample of code that deletes a file when the path is known. Thanks for any help.

I'm surprised you didn't find DeleteFile yourself.

Me too! Being new to C++ I searched for "delete file" on this site and when I didn't find a clear answer I asked the silly question. I should have tried the on-line help first. Please accept my apology.

Joaquin, you are very hard with that Guy...
He only wants to knows how to use the DeleteFile function...
if(DeleteFile("C:\\MyPath\\File.tmp"))
AfxMessageBox("The file was deleted...");

Hello
I want to put a paragraph of text into a char buffer, but I am not allowed to wrap the text onto a new line. Does anyone know how I can over come this
char buf[2000] = "text text text text text
text text text text text
text text text text text text text";
error C2001: newline in constant
error C2146: syntax error : missing ';' before identifier 'text'
error C2065: 'text' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'text'
...
|
|
|
|
|
char buf[2000] = "text text text text text "
"text text text text text "
"text text text text text text text";

You should be able to do this:
char buf[2000] = "text text text text\
text text text text\
text text text";
No generalization is 100% true.
Not even this one.

If all you want to do is wrap your source file to keep everything nice and tidy, the answer has already been posted.
If you want to embed line breaks in your text, just replace each newline with the character sequence '\n', as in:
char buf[2000] = "text text text text text \n"
"text text text text text \n"
"text text text text text text text";

In my Doc I have this:
struct ItemInfo
{
CString name;
CString catagory;
CString description;
}itemInfo;
Then in my View I have this:
CMyDoc* pDoc = GetDocument();
<br>
CString itemName = GetItemName();
<br>
pDoc->itemInfo.name = itemName;
But the program aborts when it reaches the last line of code, why?

Excuse me if I'm pointing the obvious, but have you checked that pDoc is !=NULL? Apart from this, the way you're accessing itemInfo seems OK to me.

Did you accidently put the struct definition outside the public scope?

pDoc != NULL and the struct is public. Anyother possible problems?
-Raffi

Stop just before the offending line and inspect the contents of pDoc. Does it look OK (reasonable data)?
