Everywhere in this picture you see a blank item, or empty space, a control has failed to draw of something. In this case they are all textboxes.

I think we can just draw an image that resemble the grid using this article : drawing in a datagridview Currently creating a way to make the image drawn in tile mode. Each time I develop a datacentric application using VB.NET regardless of how much the data displayed in the datagrid, I always want the grid to display full row of empty data, not just blank panel. Can we achieve this using VB.NET design time property? And also, we must not trigger the display of vertical scrollbar this way..
View 1 RepliesI'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.

I've always use String.IsNullOrEmpty to check for a empty string. It recently come to my attention that a " " count as not a empty string. For example,
Dim test As String = " "
If String.IsNullOrEmpty(test) Then
MessageBox.Show("Empty String")
[Code]....
It will show "Not Empty String". So how do we check for " " or " " in a string?
edit: I wasn't aware that " " count as character.

View 1 RepliesI try to remove empty space from a large string, using replace(), and using regex.
the replace method:
replace
Do While (stripped.IndexOf(Space(2)) >= 0)
stripped = stripped.Replace(Space(2), " ")
Loop
and with regex using its replace with : "/ss+/" - regular expression.
but I am still stuck with empty strings such as :
temp ""String
these string have lengths ranging between 3 and 8, so I have tried to adapt the replace function with something like this:
replace 2
Do While (stripped.IndexOf(Space(4)) >= 0)
stripped = stripped.Replace(Space(4), Space(1))
Loop
The code below works fine as long as there are values within an XML node (For example the <CPU>Intel</CPU> node below) but it throws an Exception error when the node value is blank/null whatever as in the example node <Monitor> </Monitor>.t's ok if the node value is blank, I just want to check for it and not throw an exception error.This question uses the following XML snippet below: Note: The tag <Monitor></Monitor> has no value in it.
<PCSettings>
<SystemSettings>

I got a text box and a panel.The textbox is at the bottom, and the panel is above it, making a open white space above it.The thing I want, is that when i type "run" into the textbox.The empty space should start displaying messages of its actions.Just like in command prompt.If you open a cmd window. (make it small) then type in "ipconfig" (as an example), the text that shows up, makes the scroll bar, follow it down.

View 2 RepliesWhen clearing input from users. What is the difference between clearing it in these two forms
txtExample.Clear()
versus
txtExample.Text = String.Empty
The only difference that I could find was that the labels aren't cleared with .Clear() (or at least from what I inferred from my book that's not possible). Is there a noticeable speed difference or should I just clear both labels and txt boxes with String.Empty
Is there anyway to catch or display the request failed with an empty response message somewhere other then in a message box, for a example in a text box? Catch request failed with an empty response message

'Draws diagonal line of dot and dash on form
[Code]....
... the top part draws a line on the form but the second part does nothing. The picColorKey is a picture box on the form.
I need to draw a line on a series of pictures: I have decompiled a movie file to 1200 pictures. I also have 1200 samples of vector data (coordinates of the line: beginning point, ending point , size of vector (length) and direction (angle)... anything). With these data I want for each corresponding picture to draw a line corresponding to this vector data for instance: picture 550 needs to get a line drawn from point (5,95) ... these are (x,y) coordinates. in direction of 5 degrees from a vertical line and length 55. Visual Basic do that? I understand there will be some work in locating the origin of the x,y coordinate system and telling the program what 'size 1' means...

I am building a 2D game where the user is a circle(:P) and the enemies are rectangles coming at him. However, my problem is that when I placed a very nice picture of space I found on the internet, the screen draws whatever it has to underneath this image. Everything works,I can still see my lives going down when something collides into me - except the fact it is all covered up by this picture. How Do I Draw everything ON Top of this - (I tried using the 'Send To Back' Command)
EDIT: The form draws everything through a timer, and the user controls his character through keys.In the mybase.load procedure:
PicBackGround.Dock = DockStyle.Fill
PicBackGround is the picture box with the image.In the paint procedure:
e.Graphics.Clear(Color.Black)
e.Graphics.FillEllipse(Brushes.Orange, Player)
[code]....
Player is a rectangle declared right at the top, Dim Player As New Rectangle(0, 0, 50, 50); There is then the array Objects, which stores all the data about the enemies coming at the player, Current_Projectiles is simply an array to store data about rectangles(bullets) that the player fires.
