Hello,
You should beware of the UNICODE problems that your code have when you compile with UNICODE defined. See the following where your problems are:
const char* FileName
= _T("C:\\1.bmp");
To solve this problem, use TCHAR* instead of char* where you want to use the _T macro.
[EDIT]
You should also use the macros from tchar.h[^] so that you use UNICODE functions when you build with UNICODE defined.
[/EDIT]
Hope this helps.

Hey. If m_FileName happens to be a CString, then just do this instead:
mFileName = FileName
instead of using anything like strcpy.
You are LUCKY you got the access violation now and not 10 months from now with 10 million copies of your app in the field

Show me EXACTLY here the m_FileName is defined or declared in his original post?

Since you are using mfc why not use CString and let all this memory allocation for strings automatically be handled for you??

Hai Vikas,
what type of variable is m_FileName

class xyz{
struct tagBITMAPFILEHEADER
{
WORD bfType; // must be 'BM'
DWORD bfSize; // size of the whole .bmp file
WORD bfReserved1; // must be 0
WORD bfReserved2; // must be 0
DWORD bfOffBits;
}m_BITMAPFILEHEADER ;
xyz()
{
BITMAPFILEHEADER ={0,0,0,0,0};
}

I am getting an error

If the code that you post is the real code there is a little error:
vikas amin wrote: xyz()
{
BITMAPFILEHEADER ={0,0,0,0,0};
}
xyz()
{
m_BITMAPFILEHEADER ={0,0,0,0,0};
}
Have a nice code day

Why don't use
xyz()
{
m_BITMAPFILEHEADER.bfType=0;
m_BITMAPFILEHEADER.bfSize=0;
m_BITMAPFILEHEADER.bfReserved1=0;
m_BITMAPFILEHEADER.bfReserved2=0;
m_BITMAPFILEHEADER.bfOffBits=0;
}
Because, I don't remember if you could use ={0,0,0,0,0} in that point
Have a nice code day

My favorite,
ZeroMemory(m_BITMAPFILEHEADER, sizeof(m_BITMAPFILEHEADER));
if you want to set everything to 0.
Does not work if a class with complex objects is embedded wihtin the structure, such as a CString, however.
I can't believe how many times I have seen code setting data structure's fields to all zeroes, when there are several dozen fields, instead of block setting the entire element. If I only had a dollar...

Hi everybody,
I need to implement Doc/View/Frame in an ActiveX control. I have tried to copy the code from a standart MFC Wizard generated SDI application in a standart Wizard generated ActiveX control, but it didnt work - all I could get was a bunch of crashes (for the document, I derived my class from COleDocument). Can anybody point me in the right direction. Any information is appreciated.
Thanks in advance,
Dennis.

hello,
i changed the background color of my dialogs in a dialog based MFC app by adding the following code:
SetDialogBkColor(RGB(150, 150, 150), RGB(0, 0, 0));
in my dialog based applications "Initinstance". However though the dialogs have all changed color, the background color of MessageBox() has not, and also the menu Button (Like File, Edit, Help) bar still follows the windows theme color. The menu options however show in white which is fine. I just want to change the background color of my messagebox and the color of my top menu.
Any pointers on how to do this?

the content of a.txt as follows:
1121234 aaaaaa
2223 asdf
222fs adfa
....
how to write the data from a.txt into b.xls?

I don't know if this will solve your problem because I am not familiar with the .XLS format, but Excel also likes .CSV files. These are files with text values separated by commas:
1,3,5 = will appear in three columns in Excel.
You could insert commas between the values on the same line like:
1121234,aaaaaa<br />
2223,asdf<br />
222fs,adfa
etc and name it "something.csv".
this is this.

222fs,adfa
and name it "a.csv"
the data separated by the commas are inserted into different cell in the "a.csv"
but I name it a.xls,the data of each line in the "1.txt" file are inserted into a cell.
How should I do?
Thank you.

Hi all,
I'm using MSXML to load and parse serveral xml files (quite obvious  ). All works fine while the encoding of the file is utf-8 but when i load a file that has the following header
?xml version="1.0" encoding="UTF-16"?
i get an error telling that the encoding is not supported.
How can I load files encoded in utf-16?
Thanks in advance,

This one will be difficult-
Here's my situation:
The owner of my company is ultra-paranoid about wireless networks. We have a few notebook PC's that will be in and out of our office. He wants all of those to have some way of auto-disabling the wireless when connecting to our network.
I'd need to detect if they have a wireless device, detect if they are connected to our network (I could get away with connected to any network on a non-wireless if I had to), and find a way to disable the wireless.
Is there a way to accomplish this? I don't need a full solution - just some pointers if you can. I have a way to find the interface info. I can use pcap or I have another library that uses the MIB (I hope I'm remembering that acronym properly). I don't know if either can tell me if it is wireless though. I also don't know if there is a way to disable an interface from within a program.
Thanks for any help you may be able to provide. This one is really critical.
Dave
