I have a quick simple question, what is the difference between a windows form and a web form? I am using Visual Studio 2008 express. I am trying to add a email form to a browser that I created and I am uncertian what type of form to use. My biggest problem is trying to understand what the differences of form types are. Are they just templates to make it easier to design on the front side or something else?

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

View 1 RepliesSo I was wondering if anyone has done their own Forms (inheriting windows form and editing the properties) and if so, what your finished result was. And, if you are willing to post a screenshot of your finished result, that would be sweet! Trying to get some ideas of what can be accomplished with customizing the default form.
View 1 RepliesI'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.
[code]...
I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.
FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]

View 2 RepliesI have a form in my project with a textbox that contains a unique computer ID number for the user. I want the user to click a button, which will open my website, and then populate the value from my software into a corresponding computerID form on my website.
The form on my website is just a paypal form that I built using paypal's website builder. It has a buy it now button and a textfield for computer ID. I need to know the computerID so that I can send the user the correct activation code.
Is there any way for me to accomplish this? All I have so far is just opening my site:
Private Sub btnpurchase_Click(sender As System.Object, e As System.EventArgs) Handles btnpurchase.Click
Process.Start("mywebsite")
End Sub

I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
I am doing a project which required the website application that I have created to be linking to the window form. As what I know is in the webform to webform, the command is "response.redirect("")" whereas for the window form to window form is "me.show form1.hide". So that is what I know.

View 3 RepliesMy company's main software package includes a hefty configuration library which loads on startup. This config library includes some mandatory settings which, if not supplied (via command line arguments), cause the entire application to exit.
This has never been an issue for our users, who launch the software via scripts which have the needed command line arguments supplied automatically. But sometimes when debugging our software we developers forget to specify the necessary arguments in Visual Studio's debug options; it's then very annoying to be greeted with the message Config specification invalid -- missing required parameters X, Y, and Z -- shutting down (I'm paraphrasing, of course).[code]...
