Hi Guys,
Have on Windows XP been using the following code to authenticate if username and password are valid up against Active Directory. But found out that my apps are not working on Visa OS as it always return false, even if user + pw is correct - on XP no problems works 110% fine there, but on vista.. urgh!
private bool doAuthenticate(string szController)
{
string path = "LDAP://" + szController;
DirectoryEntry de = null;
if (szUserName == null)
{
de = new DirectoryEntry(path);
}
else
{
de = new DirectoryEntry(path, "\\" + szUserName, szPassword);
}
try
{
Object native = de.NativeObject;
return true;
}
catch (Exception ez)
{
return false;
}
}
Any who have an idea on what is happening?
Cheers,

Create a public method in the user control that you call from the form's button_Click handler. In that method (in the user control) call the PerformClick method of the user control's button.

Because Unicode includes ASCII, ASCII is Unicode, no conversion is necessary.

Is this what you intend to do?
Which line throws this exception?

Two questions, related to the error "Cannot update. Database or object is read-only.";
- Are you "viewing" the sheet in Excel whilst running this code? If yes, then close it.
- Have you checked the properties of the file itself? Ie, it shouldn't be blocked etc.

Use the algorithm from your signature.
|
|
|
|
|
Sounds easy enough, what do you have so far?
|
|
|
|
|
If the rest of the expression doesn't matter, then iterate through the string, if the first character is a K, then accept it, otherwise if the first character is an S, check the second character and if it is an A, then accept the string. That's pretty much a simple way of looking at it and should be easily written in C#. Try to convert that to C# code, and if you have issues, post what you have and we'll try to help further.

i am new to c#.net...i am having 90 text files having image intensity values...i am reading n th row of every text file and write it into newly created text file....i have done this in matlab .i am getting correct output...but in this program i have done something wrong...because of that the no.of columns are not same in each row...i couldn't get the output image....here is the program
private void button1_Click(object sender, EventArgs e)
{
try
{
string path1="c:\\Vicky\\DATAS\\OutputFiles";
string path2 = "\\";
string path4 = ".txt";
DirectoryInfo dir1 = new DirectoryInfo(path1);
dir1.Create();
DirectoryInfo Dir = new DirectoryInfo(@"C:\Vicky\DATAS\textfiles");
FileInfo[] FileList = Dir.GetFiles("c*.txt",SearchOption.AllDirectories);
for(int t=1;t<280;t++)
{
string path3=Convert.ToString(t);
string path=path1+path2+path3+path4;
FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
foreach (FileInfo FI in FileList)
{
FileStream fs1 = FI.OpenRead();
StreamReader sr = new StreamReader(fs1);
int i = 1;
while (sr.ReadLine() != null)
{
string d="";
if (t == i)
{
d = sr.ReadLine();
sw.WriteLine(d);
break;
}
i++;
}
}
}
}

you're writing 279 same files...plus
if (t == i)
{
d = sr.ReadLine();
sw.WriteLine(d);
break;
}
this will break in every first while loop
File.Copy() can do what you need

thanks for ur reply....i don't know how file.copy() method is going to help in this program.here i am not copying the file to another path...i am just reading the the same row of every text file and copy it into new file..and u told me that this program will write 279 same files...but i am getting 279 different text files with different memory sizes....

yes, if you dont mind then your code is very tacky. All you need to do is that read all lines from each text file using File.ReadAllLines() as Danish said. That will return string[] and you can rip the line by index then add to the generic string list List<string></string>. When you done, write entire list using File.WriteAllLines()(you will need to use ToArray() to get the array from list).
