I would like to be able to change a single property for every form by code instead of doing it manually. I'm a little new to .NET development, and I thought I was on the right track with the System.Reflection class, but I still can't put all the pieces together. Here is a basic outline of what I'm thinking (pseudocode):

I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

View 1 RepliesIn my ASP.NET Web Forms I would like to get the DataNavigateUrlFields from the HyperLinkField control.
In order to get the control I use the following code in the RowDataBound event:
If e.Row.Cells(n).Controls(0).GetType().ToString() = "System.Web.UI.WebControls.HyperLink" Then
Dim linkDownload As HyperLink = DirectCast(e.Row.Cells(n).Controls(0), HyperLink)
[Code]....
Is there any way to get the DataNavigateUrlFields property? In case there is not, is there any function to extract the downloadGuid value from HyperLink.NavigateUrl (in short treating the NavigateUrl as a QueryString)?

I'm currently working on building a program that will take a MS Access database system produced by my company and create a VB.Net project with all the forms in it (obviously the code should be manually done, but to save time the forms and controls can be produced automatically).I have tried Googling and seem not to be able to find anything about this (which probably means I wasn't searching with the right keywords), I was wondering whether anyone knows any good resources on how to create the VB.Net project programmatically as I already know how to do all the access stuff.

View 1 RepliesI have a form-based application that is still in the testing phase. As a convenience while the project is in test phase, I would like to be able to open its VB project by clicking a button on the form, instead of navigating to the directory and open the project by double-clicking its icon. (I'm lazy ) I've added a button to the form. What code should I use to open the project?
View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.
View 2 RepliesI've been using this article [URL]to add into my code the ability to compile code a user enters into a text box. I was wondering if anyone knows a way that I can pass in a variable that exists in yhe program that I have written. So the idea is in my program I have a variable, let's say a filename, that is used. The user of my program is writing their own program in a text box. When I compile the program they have written I want to be able to pass the filename from my program into theirs.

This is my first post on this forum, so please excuse me if I'm posting wrong. Anyway, I've been having an issue that I've never seen before and is driving me nut, I have a windows form on which I have placed many textboxes that display information from a MS SQL database. The user can then change these values and hit a "save" button which writes the changes to the database. I also have certain textboxes that with the "on leave" event (after a user enters a possible new value) trigger a method that recalculates some of the other fields based on the new information. Hopefully that all makes sense.
So the problem is, when I run through this "recalc" method the first time around, it doesn't update those textboxes that it's supposed to. However, when I put a breakpoint in and debug through it, the debugger shows it putting in the correct values into the textboxes. It's just as soon as the method is done, it puts them back to blank, or whatever they were before

View 1 RepliesI wrote a small app we use on our computer to keep them running optimally and do some utility things (delete temp files, defrag drives, clean registry, backup my docs to the server, etc). One of the options I ahve in there is "Reset Windows to Defaults" and the objective was to setup windows how we normally would set them up before we give them to our users. So if a user messes with all his/her settings we can click this button and reset it all back. So far it resets IE settings, changes Window Explorer views, puts all the default icons on the desktop and turns off desktop cleanup, etc. Well one of the last things I want to do is change to the default Windows XP theme and apply it. After a lot of searching the internet I found this:
[Code]...
It does reset colors and stuff back to the theme. The problem is if a user has "Windows Classic" set and this is run it does apply the theme.....mostly. Things like dialog boxes stay in classic while the menu structure and desktop go the XP style. If you go into display properties it still shows "Windows Classic" but under Appearance it shows "Windows XP" which leads me to believe even though this function is for themes its actually just applying the appearance and not actually setting the theme.
