does anyone know how to connect points of a label? Let's say I have a label and start the label at point 0,0. Aterwards, the points jumps to 3,6 ... then to 6, 9 dynamically based on incrementing 3. How do I show for example, the path it takes to let users know where they are? for example, 0,0 --> 0,3 --> 3,6 --> 6,9 --> etc. I've tried with drawline but unfortunately, this leaves my lable in a mess.

I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

I have the form with a tab control on it, there are 5 tabs each with a label contained in the tab-page.I want to have a button outside of the tab that changes on the form. when clicked the button will change the text of the label based on which tab is currently selected. I know it should be possible to do this, I'm not too sure where to start.

In my vb.net project, i use to add Datagridview dynamically into a tab control. tab pages's autoscroll property is set to true. i calculated the gap between consecutive DGVWs and pass the parameter in the location as like this. [Code]
supposing if i want to 7 DGVWS, say 5 DGVWs are placed finely in expected gap until i do the scrolling the vertical scroll bar. whenever i scroll the bar(vertical) to the downmost end and then again add DGVW into the tab page. unfortunately the 6th DGVW is placed somewhere down and the gap between 5th and 6th dgvw is enormous difference. what i understand is whenever the scroll bar is brought to the bottom most end, the drawing point is taken as the current top view. i don't want like this. Is there any setting needs to be take care.

View 1 RepliesIm working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

View 4 RepliesI need to write some code which draws a predefined circular path (say 48pix diameter) and use a timer to delay it to show it being drawn. I need to use GDI+ to do this. My guess is on the Timer.Tick, I would set some Point value for the next point on the path, and then call Invalidate to raise the Paint event.
View 5 RepliesI have managed to develop a form which allows me to add a record to an access database using Adonet. The last few fields added are populated when i place the mouse over a floor plan image on the form (provide geographical location) and capture the x y coordinate. Prob im having is how on another form i get the points to automatically re-draw on a form with the same content (floor plan on it. I can obviously retrieve the data set using a data adapter/data table just cant make it draw on top of the graphic automatically.
View 1 RepliesI have an application that makes a drawing with measurements both horisontal and vertical. I like to get the vertical measurements to be in direction down-up, not up-down direction as StringFormatFlags.DirectionVertical does. All the measuretexts are drawn to a graphics path. Because that path includes all measures at different locations I canīt TransformRotate that path, the text should be rotated before it is passed to the graphics path, or ? It would be so nice if it would be a StringFormatFlags.DirectionVerticalUp to handle it.

View 5 RepliesI have a user control which is essentially a main menu I can place it into my MasterPage hard-coded, but I don't want that, I want to be able to dynamically place it with the code behind of the MasterPage.

So what I am looking to do is something like
if **condition is true ** _ response.write('<controls:mainMenu ID='MainMenu1' runat='server' />')
Of course, I know that won't work, but how would I place the control based on a condition in code behind on the master page?
