Winternals ERD commander is a good program it lets you create a CD Bootable operating system and gives you network access as well. You can create the boot cd on your dads computor it will then work in any computor. This program is not cheep. If you can get your system to boot to this cd you should then have access to your files. Good Luck

Addstring in ListBox

Hi all,

Wanted to know if it is possible to both pad a hex numbers with leading 0's and also format the width of the message.

I have a string and i just concat a hex number to it. I just want to space out the numbers so that they will line up with the next string added, so that it has the look of a table.

Right now i am padding the hex number like this:

testStr.Format("%03X" , myString);
Str += testStr;
testStr.Format("%03X" , myString2);
Str += testStr;
Listbox.AddString(Str);

I know if i take away the 0, then it will set the width, but i need to do both. CAN THIS BE DONE?

thanks in advance.

In Visual C++
=============
From the "help" menu select
Index...

From the "Type in keyword to find" edit box enter
Rtf Files /* Don't forget the space between rtf and files */

The first result is "and context-sensitive Help".
Double click on it and you will find examples with explanations.
It even has screen shot of MS Word.

I could not find this on msdn.mircosoft.com so you will need your orignal cds if you did not install all the help files.

There is a class library for Win32 that you can use with your MFC apps:
Thesycon USB-IO Class Library[^]

It has a full-featured but time limited free download and a light version with no time limit also free. It might help you.

Visual C++ .NET 2003 and XP Style

Hi,

I want to know how to programmically incorporate the XP style windows (frame, buttons, etc.) to a project in Visual C++ .NET 2003.

Beginning with Visual C++ .NET 2003, Microsoft has changed the window it incorporate window styles to a project. In older versions, an application gets the XP style under XP automatically. That is no longer true in version .NET 2003.

I have read the solution at MSDN include the one with using TheApp.exe.manifest. However, the solution requires that the program must have the manifest file in the same directory as the EXE, even in final release.

I want like to know if there is a solution to programmically incorporate the XP style windows to a project without needing the manifest file "visible" to end-users.

Thanks,
Kuphryn

I used to be able to do this with MSVC v1.52, but don't know if it's still possible with the 32-bit compiler.

Hi folks,
I need to be notified when a CDialog-derived class receive a WM_KEYDOWN message. This dialog is the main window of a secondary thread (not the main application one). I can see w/ the debug trace that the message is posted by my OnKeyDown oveloaded function is never called. Any idea about this? Thanx a lot in advance.
Best Regards;)

Interesting.

Overload PreTranslateMessage(). Does it process WM_KEYDOWN?

I noticed PreTranslateMessage works properly but the message is lost somewhere in between the MFC call stack. I am confident this could be due the fact there is a OCX control on the dialog that probably process the WM_.
How can I be notified of the message instead of the control(s)?

Hey,

i want to read Vals out of a data file. Because I don't know the number of colums and rows, I need to declare the Array dynamic.

e.g. File with 500 rows and 3 colums , i tried to use this but it didn't work:

double MyArray[iRow][iColumn];

I'd use something like one of the collection classes, like CArray<> or even vector<>.

I recommend an STL container as the other members have mentioned.

Here is one solution for a two-dimensional dynamically allocated array.

int **pData = new int *[iRow];

for (size_t i = 0; i < iRow; ++i))
pData[i] = new int[iColumn];
...

Remember to deallocate memory.

Hi Friends,
I am designing a graphical editor on which diffrent graphical object can be placed(like msword and power point). For this I require to create text control which has exactly same property as other tools provides(like msword and pwer point). I will like to know from which class I should derive my TextControl so that it can have all the property without using any third party tool.

Thanks

Is source code of ms-word for text control is available

However I don't think you could hack at it enough to make it do what you want it too. Either start from scratch designing all the classes yourself, or use richedit text control or the MSHTML control and IWebBrowser2

CListCtrl problem

Hello

Im using a CListCtrl and the subitems arent shown when I use the code below.

If I put the code in OnInitialUpdate everything works. What's the problem?

void CLogAnalyzerView::OnUpdate(CView* /*pSender*/, LPARAM lHint, CObject* /*pHint*/)
{
	CListCtrl& lst = GetListCtrl();
	if (lHint == CLogAnalyzerDoc::VIEW_LOADDOC)
	{

		CMarkup& xml = GetDocument()->GetXml();
		xml.FindElem("/log");
		xml.IntoElem();
		while (xml.FindElem("session"))
		{
			int iItem = 0;
			while (xml.FindChildElem("entry"))
			{
				
				iItem = lst.InsertItem(LVIF_TEXT, lst.GetItemCount(), xml.GetChildAttrib("stamp"), 0, 0, 0, 0);
				if (!lst.SetItemText(iItem, 1, xml.GetChildAttrib("prio")))	TRACE("%d\n", GetLastError());
				lst.SetItemText(iItem, 2, xml.GetChildAttrib("t"));
				lst.SetItemText(iItem, 3, "baks");
				lst.SetItemText(iItem, 4, xml.GetChildAttrib("group"));
				lst.SetItemText(iItem, 5, xml.GetChildData());
			}
		}
	}
}

Does the while loop get executed as expected? Do the xml.Getxxx() calls return the expected data? Are any of the calls to SetItemText() failing?
