I have no idea what you're asking here. If you download any of the sample code on this site, it should just work with your device.

So what ? You can run them through a converter, convert them by hand, or just wrap the functionality in a dll and call it from VB.NET.

I want to get drive, but when i get drive with the method .Name it work properly, otherwise error with .VolumeLabel, .TotalSize,... because it found drive "A", so what can i do?
................

This makes absolutely no sense at all. You want to get what again? What's the code you used?
|
|
|
|
|
For Each str As System.IO.DriveInfo In DriveInfo.GetDrives()
MessageBox.Show(str.VolumeLabel)
Next
................
|
|
|
|
|
All you have to do is either check the DriveType of each of your DriveInfo object, or check the drive letter to see if its lower than C. If it doesn't meet the test you want, do add it to your list control.

If you don't want to work with a floppy drive, you can ignore A and B if it finds them. Or just put the code in a try catch, each time you check the properties.

Yes i already use Try Catch, but i can't bound it to combobox, the error response "Drive not ready".
How can i ignore Drive "A" or "B"?

By ignoring those letters when you iterate through the drives. You would have to have an intermediate step and not data bind your drop list to the drives collection, but that's basically it.

I currently using VB.NET 2005, i want to connect to database on server with Ms Access.
Provider=Microsoft.Jet.OleDb.4.0; data source=//servername/d/database.mdb"
servername=socheat
after that i get error like that "Can not find instaled ISAM"
plese help me

Socheat.Net wrote: data source=//servername/d/database.mdb"
The correct format for a UNC path is \\servername\sharename\path\database.mdb
This, of course, depends on the server actually exposing a fileshare and you having Read and Write permissions to the share AND folder the MDB file is in.

Can u give me one example?
What about i get an error "Could not find installable ISAM"?

Did you fix your path format and you still get the error ?

I did in my first reply! All you had to do was change the Data Source clause to use the correct slashes. YOU have to provide the correct names for serverName, shareName, ...

LOL - you gotta love it. At least you were not mean enough to post an 'example' of a file on your network and wait to see what he said when it didn't work....

I am wondering what the next post is going to be though. The database might not have anything in it. You know, like tables!

heloo guys.. u really doing agreat job ..any way i have created strings for each shape (lines,polygons,..) each string contains informations about the shape( x1,y1,x2,y2,R,G,B,pen width) ..Now how can i make my prog read from the text and draw the shapes ..as example the line string :
public void AddSv(Line l , ref string str)
{
if(drawwhat==1)// as one means lines
str +="1"+"\n"+l.First.X.ToString()+"\n"+
l.First.Y.ToString()+"\n"+
l.Second.X.ToString()+"\n"+
l.Second.Y.ToString()+"\n"+
l.Pen.Color.R.ToString()+"\n"+
l.Pen.Color.G.ToString()+"\n"+
l.Pen.Color.B.ToString()+"\n"+
l.Pen.Width.ToString()+"\n\n";
after i draw the line i click on save to send the informations to the text :
private void button1_Click(object sender, System.EventArgs e)
{
//save
System.IO.FileStream fs = new System.IO.FileStream("c:\\graphics.txt", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite);
StreamWriter streamWriter=new StreamWriter(fs);
streamWriter.WriteLine(LineSv);
streamWriter.Flush();
streamWriter.Close();
fs.Close();
}as u can see i dealing vs 2003 .
Regards;;)

you need to read the string, then you need to parse it. It would make more sense to put commas between data items, so each shape is a line of text. They read the file as a string[] and call string.Split on each line to turn 1,2,34,5, into an array of strings, which you can then turn into numbers with int.TryParse. You can read the first number and use it to decide which function to send the array to, so that it can be parsed and objects added back to your array.
It would make more sense for the Line,Square,Triangle,Circle,whatever classes to offer a method that returns the string, so you can just iterate over your collection of base objects and call it.

I may have hit myself in the head, but didn't we have an XmlSerializer class laying around somewhere?
