I was wondering if there was a way to dispose a control that i generated at runtime in a diffrent block of code, The reason why i can't dispose of the control in the same block of code is that the controls settings depend on what the user imputs. For example if i generate the control on a timer tick the code would look like this,

I am importing data from an excel file, and it is stored in a dataset. The data is then filtered with a binding source, and that data is outputted into a datagridview. The filtered data in the datagridview contains data for 2 identification numbers. I want to graph each ID number in a chart on their own bar, in either a stacked bar graph, or a double bar graph.
I am having trouble assigning each series to an ID number: I have tried using multiple binding sources, but each seems to override the previous giving too much/too little data. I have tried using multiple datagridviews, however I cannot assign more than one datagridview as the datasource for the chart. The code I have pasted below outputs a double bar graph, however both bars graph the same ID number.

View 4 RepliesI am writing an app that puts multiple controls on a form at run time and then I edit the controls in a property grid. All that is working fine. I'd like to 'mark' the contol when it is 'selected just like visual studio does with the dotted border (or soemthing similar, I don't care that it is just like vs). I'm already using MouseDown event to grab the control and send it to the PropertyGrid, but I have now wired it up to take multiple controls and need to 'identify' them on the screen.

I am using the PowerPack and trying to change multiple ovalshape size, I have used the following code for changing multiple labels,
For Count As Integer = 1 To 100
Me.Controls("Label" & Count).Text= "Hello World"
Next Count
If I do the same for OvalShape, assume I have OvalShape1, OvalShape2.... OvalShape100
For Count As Integer = 1 To 100
Me.Controls("OvalShape" & Count).Size = New System.Drawing.Size(20, 20)
Next Count
The above throws error when executed.

c1d2

These will all contain the same items and I need to add them at runtime. I know how to loop through the controls, but not sure how to make sure I'm only editing the correct comboboxes. (I will have to do this for 2 more sets of comboboxes with similar naming conventions as well)

View 2 RepliesI wonder how you can make a picturebox selectable at runtime and also change the size and location during runtime?
Well I know how i can change the location of a picture box during runtime but that is only with a picturebox that is already defined in the form before runtime.
So I write an event for that particular Picturebox.
But now i want to do the same thing with a picturebox that a user can add during runtime and then the user should be able to select and move the picturebox.
So now i can't add code to the picturebox event so I wonder how you should do this. ( Maybe with reflection?)
And what if the user added 10 picture boxes and selects a certain picturebox. How do you make it possible that the picturebox the user clicks on is selected?
Should you store each picture box location on the Panel and then when the user clicks on a certain pixel in the panel where a certain picture box is it get's selected?

At design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?

So I wrote a VB.net project in Visual studio.I have a scheduled task that is set to run the program every morning at 10AM. If I use windows explorer and double click the application, it runs fine.If I open task scheduler, open the task properties, and browse to the application, then choose run, the program fails, due to Runtime exceptions.I know I have the path entered correctly, since I can debug the instance when it crashes from the task scheduler. VS2010 pulls up my source code.The exception is System.IO.FileNotFoundException, remember, it works fine when I double click the app. If attach a debugger to the process after it is executed from the task scheduler, I can then restart the debugger, and Voila!, The application runs fine.

When i set a breakpoint on the "Private Sub Gen.." line, and step through the code line by line, it inserts a new column for each variable declared, so in this case it will insert two columns before it even hits the "If MyBooleanValue()..." line (I can watch it actually happen due to the Excel app being visible). However, if i dont set a breakpoint and just let the code run straight through this doesnt happen.There is no multi threading happening or anything else that i suspect would have any impact on the code.

I am writing an application in which we have a Product Module, Now instead of defining individual products, we want to just state the Size Ranges in Width, height and different size scale available, and then automatically generate a list of products with all the Size combinations. I cant figure how to do this.Ill give an example.This is how we define a product
Product[code].....
If i had a fixed number of Size types i would just run For loops within for loops and inside the inner most for loop write an Add Item statement with Index of evry selected item, however since the Size types are dynamic, i need to write a recursive loop, and i just cant figure how to.
