Trying to create a set of controls that can be used repeatedly without copy and paste code, including a textbox, a set of radiobuttons and then another textbox. Having a major problem in that I can only get one radiobutton to show up.

What would be the best way to run a subroutine over and over again every X seconds. I want to avoid creating an infinite while loop to do this because this sub needs to be called repeatedly while the rest of the program is still active and responding.

View 2 RepliesBackground Story: My program contains a form and 3 buttons (Add New, Delete, Edit...etc), and it works perfectly. Recently, I decided to add menuStrip, since it helps end-user to work faster. So, I put the menu strip coding.
However.....Sometimes, it works normally. But sometimes it works very strange.
Strange 1. When I chose the "Add New" item in the menu, the Add New Form will be showing up, and then I clicked on the Cancel button in the Add New Form. The Form kept showing up repeatedly. But sometimes, it works normally. (Note: Add New Form's Cancel button contains one line simply coding, it's "me.close")
Strange 2. When I chose "Delete" item in the menu, the MsgBox showing up (since I coded it and it's a warning message to end-users), but the MenuStrip KEPT showing up, so the MenuStrip overlapping the MsgBox. (I expected the MenuStrip disappear in this situation)
Is some codings I have done incorrectly?
Here below is the coding:
CODE:
I had a program in VB6 which used the XMLHTTP to request a page from a website. The data is stock values and the remote site is using a technic to "sleep" for 4-6 second and then to response to request because its the free edition. So the VB6 looked like it hangs but it was not

What would be the best approach to create the following: A groupbox that contains several labels a groupbox with an array of 8 labels in it
Then the main form would have 4 of these groupboxs (object?) and I would need the ability to change the color and text of all the various labels within any of the groupboxes, using an index similar to what we could do with control arrays in VB6.
I would think an object would make the most sense but can you have control elements in an object and display them on the form?
I want to create controls in runtime and attach them to an already connected database..
the controls must vary e.g.Array of Strings can be used.
how to place these controls on a panel in a orderly fashion.
I would like to expand my knowledge of VB.NET and was looking at creating custom user interfaces or custom controls. The type of things I am thinking of is: [URL]s. How are those controls created? I imagine it involves using the existing controls in Visual Studio as a starting point, and altering them to suit your design?

Do i need to run other commands in conjucation with it? I found my program still displaying same old look but other one application showing office 2007 look.
View 1 RepliesI'm trying to create a planning program by using my own controls.I first make a control to create the entire field with a flow panel at the top for the header.Then below that flow panel I put a flowpanel for each row.Each flow panel in a row has four labels and one regular panel.The second control I make is one that creates a bar created from 2 pictureboxes and a panel. The panel is then variable based on the number of days it covers.
This control is then positioned in the regular panel of each row flow panel. (still with me??)I have not counted the amount of bar-controls that are put on the form, but there are a lot.and then I get the error: Error creating window handle.So I must be doing something wrong, but then how can one create a planning like panel with horizontal bars in different sizes depending of the amount of days.
I've created some messy code to look at the Readystate of each WebBrowser control and using boolean variable to track which WebBrowser control is done what. The time it takes to load 1000 URL's with one WebBrowser control is about 10 minutes. Multiple controls are needed for speed.
Here's the pseudocode of what I want to do:
Read a line from a file
Which WebBrowser is currently available to do work
Navigate to URL
Which WebBrowser is done loading a URL

View 3 RepliesI want to build my first user control using VB.NET 2008 Express. This control would simply inherit the ComboBox and use some event handlers to do an intelligent auto-complete function. When it's finished, I naturally want the control available in the toolbox so I can add it to forms in design mode.Is there a good tutorial on how to do this with VB.NET 2008 Express? Should I create this as a stand-alone project or as part of the first project where I will use it?

View 1 RepliesI have a form I am designing for work, and there are 3 combo boxes I want on it that display the same choice (unit of measurement selection). Now instead of 3 separately named boxes, I wanted to make an array of combo box, now I thought if I created 1, then copy pasted it would make them an array as the same name but it just lists the new one with a default name.

View 16 RepliesHow to properly create custom controls containing populated lists?For example: I need a combobox control which contains a list of products, then I would reuse this control in other project.
[Code]...
and it works but when I run the project each item is duplicated - this is because list is populated twice. First when user add a control to form, second by designer when project is started.I already found a solution to prevent adding items in edit mode, but this is not what I need. I would like to have them existing in edit mode so they could be edited at this point.
Does anyone know where i can find a control for creating reports, e.g. in a pdf format?? Or do i have to create my own report on a form and print the form??

View 6 RepliesI am looking to create several custom controls (PictureBox Derivatives) on during runtime. I've read that the best way is to create template controls that will be created, and duplicate them in the Controls array.
Well, that's all fine and dandy, but what's the best way to store the template? I considered a seperate form with all the templates laid out on it for easy access for my editing, and keeping them out of the user's sight. I also considdered doing a Struct for each template, and smply mirroring values onto the control being created from the Struct to the created control.
I'm looking for ease of development first and foremost, as I'm most likely going to have a vast number of these templates, and keeping the system as simple as possible will eliminate a lot of hair-pulling. After development ease, I'd go for optimisation.
Supposedly I have a datatable containing 2 columns (controlname as string, containing the name of the control and controltype as string containing the type of the control), for example ("label1", "Label") On runtime i want to loop over the datatable and create the controls from that datatable and add them to the form accordingly. but the problem that i don't know how to convert the control name to a control type, meaning that i want to convert label1 to a type of control Label, inorder for me to set its properties on runtime. so how can i do this and is there a way to convert the string to control according to it controltype.
