You should have a driver supplied with your USB stick. What you will need to do in your application, is open the driver using CreateFile and then you can exchange commands with the driver using DeviceIOControl (or you can also use ReadFile and WriteFile, but that depends of how the driver is implemented). Normally, everything should be described in the documentation of your device.

How can we find a text in RichEditCtrl . i am using CRichEditCtrl and FindText()
is returning only 1st Occurance of that Text .
|
|

Use CHARRANGE, which is member if FINDTEXTEX.
In following example control will be looked for whole range
FINDTEXTEX ft;
ft.chrg.cpMin = 0;
ft.chrg.cpMax = -1;
ft.lpstrText = (LPSTR) lpszmyString;
long n = pmyRichEditCtrl->FindText(FR_MATCHCASE|FR_WHOLEWORD, &ft);
Now if you want to find string betn range 4th char to 7th char yoiu need to mention it like,
FINDTEXTEX ft;
ft.chrg.cpMin = 3;
ft.chrg.cpMax = 7;
ft.lpstrText = (LPSTR) lpszmyString;
long n = pmyRichEditCtrl->FindText(FR_MATCHCASE|FR_WHOLEWORD, &ft);

Hello All,
I am trying to read a text file & add the words and offset in to map table.
Can anyone please tell me how to calculate the offset of the words in the file ??
<code>
#include<iostream>
#include<map>
#include<string>
#include<fstream>
using namespace std;
typedef map<string,int> FileMap;
#define SIZE 255
char sBuffer[SIZE];
int main()
{
string word;
int offset;
FileMap FMap;
ifstream fin;
fin.open("D:\\Demo.txt",ios::in);
while(!fin.eof())
{
fin >> sBuffer;
// FMap[sBuffer]=offset;
}
fin.close();
cout << "\n Enter Word:";
cin >> word;
offset=FMap[word];
cout << "\n Word Offset is :" << offset;
return 0;
}
</code>
Thanking you,
Suresh HC.

What do you mean by offset exactly ? The index (in the file) of the first character of the word ? If yes, in your loop you can simply increment the offset counter by the size of the last word read:
while(!fin.eof())<br />
{<br />
fin >> sBuffer; <br />
offset += strlen(sBuffer) + 1;
FMap[sBuffer]=offset;<br />
}<br />
There is also a flaw in your design: if the user enters a word that was not stored in the map, then you'll get a crash. It is better to check if the key exist in the map (using the find function).

Check out the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\dontdisplaylastusername registry value.

Did you read the link I provided? That particular registry key has nothing to do with other applications. It's for the OS.
For your application, you can do it however you see fit. For example, when the application first starts, read the values from the registry (e.g., HKCU\Software\Local AppWizard-Generated Applications\AmitsApp) and pre-populate your login dialog box.

I have two edit controls in a dialog - the 1st is CEdit and the 2nd is a custom class derived from CEdit which supposedly accepts file and sets the edit box.
Now my problem is upon dropping a file to the 2nd edit box, I want just the filename to go to the 1st edit box.
Any thoughts on how I should go about this?
Thanks!

My problem is with setting the text in the 1st edit box which I will get from the
2nd one upon dropping the file.
The handler to the drop event is in the class of the 2nd edit box. Am I on the right
path on this? Please help.

Send a custom message to your parent window to set the text in 1st Edit box.
NoteIf you use local variable, to pass the string in WPARAM or LPARAM then make sure you are sending message using SendMessage API..
