With Me<br />
If .radAdd10.Checked = True Then<br />
<br />
.ProductTableAdapter.UpdatePrice(1.1, .Category_IDTextBox.Text)<br />
.ProductTableAdapter.Fill(.ComputerDataSet.Product)<br />
Else<br />
.ProductTableAdapter.UpdatePrice(0.9, .Category_IDTextBox.Text)<br />
.ProductTableAdapter.Fill(.ComputerDataSet.Product)<br />
End If<br />
End With<br />

like this update i click on rad-10 and rad+10 whole column will add together...how do i add on specific row ....thanks

You need to change the values of the specific row, which means you need to grab the value from that one row, and change it. If you rebind then you will change them all.

Your view has properties for items, columns and rows. So, you change a specific value by accessing that row/column and changing it.

Hi All,
I'd like to build a video-phone, where the voice and video from my PC can be shared with some else and v.v. I'm not sure where to start. Can anyone recommend an article or other good starting place for this?
I'd like to use VB.NET or C#.NET.
Thanks!
Chuck

Aha! That's giving a whole lot more results than searching for "videophone". I'll have a look. THANKS!

Hi,
I want to print a bill as follows: (Sorry it's in Dutch, but it doesn't matter for printing)
"www.uploadgeek.com/uploads456/0/factprev.jpg"
That means i want to print a logo in the upper-left corner, 5 lines of text in the upper-right corner, then print a horizontal line and above that line print "Factuur". Below that line i want to print 4 lines of text at the right AND the left.
Please help me out.
Thanks, 
Zaegra

Hi,
I don't know how you did this, but the URL is not visible in your post; it is visible
when I start a reply though, on top of the edit window I am typing in.
I haven't seen the JPG, uploadgeek seems extremely slow...
anyway, the normal way of doing print stuff is create a Control that somehow shows your
output on screen, then do the regular print operations to get that Control printed,
i.e. the OnPaint() method you create to display on screen will also be used when printing.
I tend to use a Panel, and paint all strings and images myself (with Graphics.DrawString
and Graphgics.DrawImage).
You can see a one-page printout example in my Sokoban article (it is C#, but exactly the
same stuff can be done in VB.NET).

Hey,
That link is weird indeed, i don't know what happened.
I really don't know how to print the text and logo at the right positions on the paper. Can you give me one of your examples in Visual Basic? Here's the image again, using ImageShack now

Hi,
I don't have much VB.NET code at all, and none of it prints.
My Sokoban article should be sufficient to solve your problem, read it, look at the
relevant code, and ignore the syntax differences (mainly brackets and semi-colons !).

Use the Graphics.DrawString Method (http://msdn2.microsoft.com/en-us/library/system.drawing.graphics.drawstring.aspx[^]) to draw you strings in your printPage-event (graphics.drawImage for your logo).
To right-align a string use graphics.measureString, get the width of your string and subtract the width from your printdocument's x-coordinate, that you want to be your right hand border.

Yes, that should work. I'll try that. Someone knows what the maximum size of an A4 Paper Format is(x,y)?
|

1. DrawString is what I told you from the beginning
2. the printer will tell the Framework, and you will find out through the PrintPage event
and its PageSettings.
Again, look at a working example.

hi
thanks for your kind rep.
yes you are right but if i close the application and run it again the the password remains same as old pasword it's not changing the default password, because waht if user want to change password ?
waiting for your kind rep.
have a nice day

The code you wrote changes the password just during the execution of the application. When you starts it again the password is recovered with the one you have in the Tag property. If you one that the change persists then you'll have to store it outside the code and get and set it when you want. Maybe the easiest way would be to store in one of the project settings. For example: My.Settings.Pwd
and get it when the application load the main form

Obviously, changing hte password in memory does not change your code. So, you need to write code to persist the password. Naturally, if you just store it as plain text in an XML file or the registry, people can just look it up, to get into the program. So, you need to encrypt it somehow.

File.SaveAllText and File.ReadAllText will give you file access. How you encode it, is up to you.

this is what i have done
Dim MyFile, FileName, LoadPW As String<br />
Dim MyIFile As String = Application.StartupPath + "\Password"<br />
<br />
Private Sub CreatePassword()<br />
Dim DataWriter As System.IO.StreamWriter<br />
FileName = "dk.txt"<br />
DataWriter = File.CreateText(Application.StartupPath + "\Password\" + FileName)<br />
DataWriter.Write(txtPassWord.Text)<br />
DataWriter.Close()<br />
End Sub<br />
Private Sub LoadMyPW()<br />
Dim DataReader As System.IO.StreamReader<br />
DataReader = File.OpenText("Password\dk.txt")<br />
FileName = DataReader.ReadToEnd<br />
LoadPW = FileName<br />
DataReader.Close()<br />
End Sub
so it's working fine but still i have to do few changes with this code about encodeing which i will do it 2 moro

Hi,
I have a problem when I am trying change printer properties in Excel with VBA code. I can change those properties but what after that? My printer is a labeler and it automatically scales the print area to fit in its label when I press manually "OK" in print properties- and in page setup- windows. How I can do this by using code? I have already tried to scale the print area in Excel to be the same size as the label but messes up the size of text etc.
|
|
|
|
|
I found a solution. I make a picture in other sheet and set up the pictures formula to be that area which I want to print. Then I scale the print area in other sheet and picture with the area. And then print it. It worked.
