I have a form ( call it NewForm ) that can be opened from many other forms, but I don't want to have the user to run into the problem of having many windows/forms open.I want to close the calling form and open NewForm.NewForm will prompt the user for information, but if the user doesn't find what they are looking for I want to have a "Cancel" button on the form. With the "Cancel" button I want to go to the previous form.is there a way to tell which form called NewForm so I can just reopen/unhide that form/window.

I know the WebBrowser's use IE for the core, but no other IE shortcuts seem to work, other than the Ctrl+N (new window) one. It wouldn't be so bad if it didn't open IE, and my opened own application, but it doesn't. Any way to prevent this or make it open a copy of my own browser, instead of IE?

I am using VS 2008, Windows XP R3, and Visual Basic.When I open some forms in the form designer, (In Solution Explorer, right click on the form, then select View Designer) the form always opens as Edited. An Asterisk "*" appears after the form name in the open window tabs. If I open the form to just view the code (In Solution Explorer, right click on the form, then select View Code), the form opens normally. This happens for just some forms.
It always happens for the same forms, and never happens for the other forms. What I am missing in those forms where the designer always thinks the form has been edited?

I've written an interface with a 3rd party web service in VB.NET. The final step in that interface involves the 3rd party delivering to us (as a stream) a PDF document. After streaming is complete I save a copy of the PDF on our servers, so that our users can view the PDF by clicking on a link in our system. The PDF opens fine in Acrobat X, but when I try to open it programatically I an error saying that "the file is damaged and could not be repaired". I can also open the file in IE just fine, with no issues, and the same code that displays this PDF works just fine on lots of other existing PDFs that predate the 3rd party interface.
I have emptied out temporary internet files as suggested in some posts I saw online. I also opened the PDF in Notepad++ and the %PDF tag is first, and the %%EOF tag is last, so there's certainly no corruption visible in the document source that I can see. Below is the (very standard) code we use to open PDFs into a separate browser instance on our site:
PDFFile = System.AppDomain.CurrentDomain.BaseDirectory & Request.QueryString("LetterPath") & Request.QueryString("Letter")
Response.Clear()
Response.ClearHeaders()
Response.BufferOutput = True

I'm just starting to write a program to manipulate some intranet based databases using the web browser control, but have a problem with one specific database.I can log in from the start page of this database from my browser but it then opens in a new instance of IE (I think it's the java code (not java script) which does this when the page loads).How do I get it to open in my browser?OK, I can manipluate it with a doc object, but would prefer to do it in my browser for consistency, as the other databases open fine in my brower.I can't be more specific but could post the html text if necessary.Currently using the built in web control with VS2005 running on XP.

I am new to these forums. I had a VB.net class several years ago and cant seem to find this info in the text from the book used in the class. Here is what I would like to do. I have a 2 forms.

When I click on one of the three buttons (on form1), I want to fill the listbox (on form 2) with one of three arrays. is this possible, it seems like it should be.

I am a desktop programmer, not a .NET programmer, but have been asked to look at a .NET application that sends data to a Word document if a user selects an icon. It worked fine until the user upgraded to XP. (The Word version is 2003 and did not change.) Now, although it still works, it opens 2 Word windows - one with the correct data, and another that is empty (it doesn't even have a blank document). The user has requested that we eliminate the empty window. The .NET code calls WORD via:

I'm facing a problem with my code. it's all about an if command. When the variable
xglobal doesn't fit the rule (if xglobal >=0 and xglobal<=xlimite) a message box should appear, so it does. However, after being closed the message appears again and so on.
Below you can find the code:

I need to create a program that requires password entry. I was thinking of having a form that the user uses to set the password that only opens once (unless a button on the main form is clicked to reset the password.) once the password has been set, the form closes and another opens to enter the password and for each and every time the program is run. Another thing is that if the password has been entered wrong 3 times, the program gives a message box and closes on the ok button.

I developed a winform .NET 4 application that has the ability to asyncronous save image from scanner using Bytescout Scan. Anyway I noticed that in some cases (with some scanners) the scanner's GUI opens and then closes immediately after load without performing any scan. Since no error message is raised either from my code and from scanner software itself; is there some settings/tweak somewhere I should pay attention?
