I use checker = atoi( (LPCTSTR)str) to convert CString to int and checker to check if the number typed in CEdit box is within valid range.

Now the problem is when user type a number then follow by letters. 1234abcd would return checker as 1234. How would I go about checking for non-integer characters?

Or is there anyway to limit user to only type in integers?

One good way to parse your strings is to use _stscanf like so:

int a;
CString mytext = _T("123Hello");
if(_stscanf(mytext, _T("%d"), &a) != 1)
{
// An error happened
}

// a now contains the number if parsed correctly

hey everyone
i have this project i need to do that uses setwindowshookex to set a message hook on a given process ID and for each keydown that that screen gets i replace the key with the char from a given text file
so like
the procces ID is notepad and the file is Omri.txt witch has
"Hello World" in it
so if i type in notepad "asdasdasd" it will type "Hello Wor"
anyway, thats the project
so what i did is make a DLL with the functions
open file
close file
get char
set hook
unhook
and getkeys
getkeys is the function windows calles when a key is pressed

so my problem is, when windows calles the function it cant access the opened file becuse it gets a difrent data field
i tryed puting the fstream var in shared memory but it didnt help
anyone here got any idea on how i shold do this?

Hi, everybody,

I develop a browser helper object. I need to update the address in the address bar to a different address after user navigates to it. I tried to handle the NavigateComplete event but failed to make change to the address. Any change that makes to the address causes crash in IE. How can I solve this problem?

Thanks.

Binary Resource Data

Visual C++ 6.0, SP/5

I'm trying to use a binary resource in my executable, but I'm not having any luck.

I've looked all over MSDN and the web, and I've found nothing that gives clear instructions on how to do this.

Anyone got any hints/tips?

If by binary you mean RT_RCTYPE, check out this article.

Found the following on CodeGuru. I adapted it to my needs and all is well. Smile | :)

<br />
For each file you want to include, add a line to resource.h as follows:<br />
<br />
  #define IDR_MYFILE 103<br />
<br />
Remember to give each file a unique resource ID.<br />
<br />
Close all resource files and open your .rc file as "text." Add the line<br />
<br />
  IDR_MYFILE RCDATA DISCARDABLE "res\\myfile.ext"<br />
<br />
A good place to add this line is immediately after the line which defines the IDR_MAINFRAME icon. If you haven't placed "myfile.ext" in your "res" subdirectory, adjust the path accordingly. Save the .rc file. Close it and open ResourceView. You should see something like this:<br />
<br />
There are more convenient ways of inserting a custom data resource, but they either embed the file as raw hex data in the .rc file, inflating it to several times the size of the included file, or neglect to define the resource ID in resource.h so that ResourceView shows the ID in inverted commas.<br />
<br />
To turn a resource back into a file, load it into memory using LoadResource(). This returns a BYTE pointer that CFile can use to write that file to disc.<br />
<br />
// Load the resource and save its total size.<br />
HRSRC hRes = FindResource(NULL, MAKEINTRESOURCE(IDR_MYFILE),RT_RCDATA); <br />
DWORD dwSize = SizeofResource(NULL , hRes);<br />
HGLOBAL MemoryHandle = LoadResource(NULL, hRes);<br />
if(MemoryHandle != NULL)<br />
{<br />
  // LockResource returns a BYTE pointer to the raw data in<br />
  // the resource<br />
  BYTE *MemPtr = (BYTE *)LockResource(MemoryHandle);<br />
  CFile file("C:\_my_path_to_file\myfile.ext", CFile::modeCreate | CFile::modeWrite);<br />
  file.Write(MemoryHandle,dwSize);<br />
}<br />
FreeResource((HANDLE)hRes);<br />
<br />

Splitter Window get/pass information

poiut8-Apr-05 5:33

I am using MFC with Explorer style. Basically the Left panel split has it's own class and own file. How would I get LeftView to get/pass information to? I have never actually done get/pass class info which isn't declare in the other one.

Would it be similar to

inline CClassDoc* CClassView::GetDocument() const
{ return reinterpret_cast<cclassdoc*>(m_pDocument); }

Thanks

Re: Splitter Window get/pass information

You could do something like this, inside your frame that created the split.

CLeftView* CMyChildFrame::GetLeftPane()
{
	CWnd* pWnd = m_wndSplitter.GetPane(0, 0);
	CLeftView* pView = DYNAMIC_DOWNCAST(CLeftView, pWnd);
	return pView;
}

How to use non .NET DLLs in .NET environment?

Khang Nguyen8-Apr-05 5:30

Happy Friday! Gurus,

I am trying to use the logics from Intel OpenCV DLLs, which were originally compiled by MSVC++ 6. From C# or ASP.NET Apps, when I was trying to add reference to these DLLs (i.e. cv096.dll or cxcore096.dll), I got this error:

“A reference to ‘D:\Programs\OpenCV\bin\cv096.dll’ could not be added. This is not a valid assembly or COM component. Only assemblies with extension ‘dll’ and COM components can be referenced. Please make sure it is a valid assembly or COM component.”

Note: The source code of Intel OpenCV DLLs is open source. I can open this source code project in either MSVC++ 6 or VS.NET 2003.

Question: How can I use these DLLs in .NET environment, preferably in ASP.NET and C# projects?

Thanks with a million
Khang

don't know about those specific DLLs, but you can import functions from C-interfaced DLLs (ie. non-COM, non-MFC) by using the DLLImport keyword

ex:

[DllImport("MyDll.dll", EntryPoint="DLLFunctionName")]
public static extern ...return type... DLLFunctionName(...params...);
