Hi,
This is an ASP.NET code-behind file. But there is no post back here. I click Button A and dataset gets filled with data. Now I put a break point in button B click event and inside that button I check if this dataset using Quick Watch in VS 2003. But although inside Button A click event handler the ds showed 1 Table, inside B's click handler its showing zero Tables.
|
|
|
|
|
I think the page is redeclaring the DS when you click the first button.
Try to add the DS to viewstate.
Then in the 2nd button, use the DS from viewstate.
|
|
|
|
|
ViewState is not returning data as well, I am now populating a DataSet everytime I need to get the data.

How do i writ a code to extract a file and save it in a folder?
|
|
|
|
|
|
I actually need a code in c# to extract files from a folder that was extracted from a SWIFT machine
|
|
|
|
|
What is a SWIFT machine ? Is the folder compressed ? As a zip, or something else ?

Its just an ordinary folder (very large though) that has a lot of files and i need a code to extract these files and save into different folders for easy accessibility
|
|
|
|
|
Use
System.IO.StreamReader;<br />
System.IO.StreamWriter;
|
|
|
|
|
after using
System.IO.StreamReader;
System.IO.StreamWriter;
then what next.I actually need a procedure,thanks
|
|

Hope this helps:
try<br />
{<br />
string fileContents;<br />
<br />
using (StreamReader sr = new StreamReader(FileName))<br />
{<br />
fileContents = sr.ReadToEnd();<br />
}<br />
return fileContents;<br />
}<br />
catch (Exception exc)<br />
{<br />
return exc.Message;<br />
}
To write contents to a file use StreamWriter instead of StreamReader.
Then use yourStreamWriterObject.Write(ContentWritten); to write the contents to a file.
Hope this is helpful enough to you.

If you're just moving/copying files from one place to another then File.Copy and File.Move may interest you.

hi,
adding days,months,... is not that hard. the DateTime structure provides the function for that.
just do the following:
DateTime dt = DateTime.Now; //getting present date and time
dt.AddDays(7);// adding 7 days to it
dt.AddDays(-4);// subtracting 4 days
hope this helps
regards
|
|
|
|
|
DateTime dt = new DateTime(2007, 05, 25);<br />
dt = dt.AddDays(7);
|
|
|
|
|
You can use Datetime.AddDays method

Bitmap bm = new Bitmap(@"c:\Hamtaro.jpg");
Graphics gr = Graphics.FromImage(bm);
gr.DrawString("Hello Graphics", new Font("Verdana", 10),
new SolidBrush(Color.Tomato), 1, 40);
Error 1 Cannot implicitly convert type 'System.Drawing.Image' to 'System.Drawing.Bitmap'. An explicit conversion exists (are you missing a cast?)
And sorry, how do you save it eventually??

hi,
i don't see why the code doesn't work??
i tried the code below and it worked fine.
you can use the save function to save the new image.
Bitmap bm = new Bitmap(@"c:\testimage.jpg");<br />
Graphics gr = Graphics.FromImage(bm);<br />
gr.DrawString("Hello Graphics", new Font("Verdana", 10),new SolidBrush(Color.Tomato), 1,40);<br />
gr.Dispose();<br />
bm.Save(@"c:\testimage2.jpg");
regards

you're still not cleaning up your resources.
using (Bitmap bm = Bitmap.FromFile(@"c:\Hamtaro.jpg")/* as Bitmap */)
{
using (Graphics gr = Graphics.FromImage(bm))
{
using (Font f = new Font("Verdana", 10))
{
gr.DrawString("HelloGraphics", f, Brushes.Red, 1, 40);
bm.Save(@"c:\Hamtaro.bmp");
}
}
}

This's C# not Excel.. You have all the tools, do it yourself
My small attempt...
