View 4 RepliesI am currently creating a program that outputs an image, but the image being outputted consists of text and other graphical elements.
So the text element would look like:
graphics.DrawString(text, variable, variable, variable, variable)
My problem is that I cannot create more than one set of each element that I am creating. And then put that into the code that creates the image. Is there a way of creating this line of code and then putting it into say a variable and then putting the variable into the code where the image is created?
Now I'm creating at app in VB (Microsoft's, Visual Basic 2010) which will be in full screen but I want to know if I can put all my content in the centre of the screen. At the moment it's at the far top, left of the screen. When the screen size varies I want it will stay in the middle for all shapes and sizes. Like :
<div style="margin: 0 auto; width: 500px;"></div>
But this is for web pages using HTML and CSS.
I'm trying to use the timer (not a Timer object) in a Do... Until loop. I want the loop to put a single variable into a label. When I do this it works and puts the value into the label (lblOxygenReading):
If btnGetOxygen.Text = "Get Oxygen Reading" Then
Select Case True
Case rdoColorWhite.Checked
strCurrentColor = "White"
Case rdoColorRed.Checked
[Code] .....
It goes through the Do loop and the For.. next loop but doesn't change the label. Visual Studio doesn't show any errors when I'm writing the code, but when I run it, it hangs somewhere.

View 6 RepliesI need a little advice in manipulating DataGridView in Visual Basic .Net. This is my first time playing with DataGridView. My program is to load a .txt file containing data of every room in a building and display them in the DataGridView. Here is a portion of the file showing 2 rooms:
1;1812;1812;F18;T1;26808.16;.00;.00;.00;.00;.00;.00;
1;1813;1813;F18;T1;24000.00;3500.00;.00;300.00;.00;.00;.00
A room is a one-line string that ends with an endline character.I have no problem with loading the file and getting all these information. I store data of each room into an object of class Room, and put them in a list.Right now, I put all of the properties of the room into the data grid's columns like this:
Now, how can I put all these rooms' data into the grid? I tried follow [URL].. at first, but setting DataSource to a list of class Room imitating from the given link doesn't show anything in the grid view.How can we tell the program to link rows of the grid to a list of objects? Or am I doing it wrong?
This is with Visual Basic 2005 or with Visual Basic.net 2003 I am asking this in regard to. The point here is that I need the space that the Tab pages will offer but it is on an Mdi "backbone".
View 11 RepliesI have a vb.net window app that has a number of combo boxes on it. These are being populated from a number of XML files and all this works like a charm. The problem i have is when it comes to putting the comboboxes in a datagridview. I have set up my columns and have set the first column to be a combobox but i'm having problems referencing this so that i can set the datasource to populate it.
I've looked everywhere but cant seem to find how to reference this control. Once this has been selected it will populate a second combo box based on the data from the first. I think i can sort this out, if i could only work out how to set the datasource of the first combo programatically.
