I did a MDI Winforms application and noticed behaviour that I have a question for. If one of the forms is opened with a Maximized Window State and another form is opened with a Normal Window State, the form Window State that used to be Maximized is changed to Normal. Can several windows be open in a MDI form with different window states at the same?

I've created a shared add-in for Office that adds a button to Office application.
If I am using the button to show a message, it works good:
Code:
Sub settingsPressed(ByVal control As Office.IRibbonControl)
MessageBox.Show("Hello")
End Sub
But I am not able to use it for opening Windows form:
Code:
Sub settingsPressed(ByVal control As Office.IRibbonControl)
frmSettings.Show()
End Sub
The .Show() command is not available and is not proposed by intellisense.
Of course I've added a reference to System.Windows.Forms

View 3 RepliesI have a print driver Windows app that uses a web service to connect to an authenticate its credentials. But the problem is, I don't want a user to login every time they want to print. Basically I want the login part of the app to only pop up if the printing functionality hasn't been used in 20 minutes.
tell me what would be the best way to go about this? I'm unfamiliar with Timer functions. This app isn't always on. It's on briefly then closed. So I need a solution where the timer is set somehow on the computer.And I don't want to write data to a text file when it can just be edited..
When I select a standard windows form at design time, then in the toolbox, under the "general" section, there are ellipse, line, and rectangle, but they are all gray and so can't be used and I can't find any way to make them not gray and thus usable. What am I missing? The help system tells how to USE them but nothing about how to make them accessible, it just assumes they are.
I have no problem drawing a line on a form at run-time but I want to drop one on at design time and can't find any way that's my real problem.I'm not a heavy user of VB.NET so I figure there's probably something simple that I'm overlooking.
I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}

View 5 RepliesSince last 2 days I have been getting a strange problem with my Vb programming (VS2005). Whenever I open any Vb or C# code and press F5 (in order to debug), several windows open at a time like Memory1, Memory2, Memory3, Threads, Processes, Registers, Data sources. And simultaneously the SOLUTION EXPLORER that is present at top-leftmost corner generally goes missing. When I restore that and put my cursor over SOLUTION EXPLORER, the program hangs and a message comes as : "Microsoft Visual Studio has encountered a problem and needs to close".I have attached the screen shots of the problems to this Thread.I tried various ways like restoring my computer to an early date, repairing Windows XP and then uninstalling and reinstalling Visual Studio. But none seem to work.
View 15 RepliesI am having a serious issue with Visual Studio 2005. Whenever I open any Vb or C# app and press F5(to debug), multiple windows open simultaneously like Memory1, Memory2, Threads, Processes, etc... Also, SOLUTION EXPLORER goes missing from top-leftmost area(where it is present usually).

There is no option to attach something, otherwise I would have attached the screenshots of the problems.

View 4 RepliesI am making a webbrowser,how to prevent my browser from opening new IE windows. Because what happens is, there are some links that will open new windows and therefore IE comes in place because it is set as default windows browser which I really don't want because my browser looks really bad if it opens links in another webbrowser.I want it to be just a basic browser, it has only one window, and it should navigate within that window. This is because the browser is integrated in a bigger application only for some website applications that are related to this main application.I am using VB.net 2008 Express Edition?

So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

I'm writing a windows service (MacTimeFix.exe) to fix the Windows time on a Macintosh (it's like this: i live in Moscow (GMT+03:00), and Mac OS thinks that the system time is GMT+00:00 and adds 03:00 to it< and Windows thinks that system time is the local time).I need to execute my code when my VB app is closed. (it happens with the shutdown of Windows) The form is invisible (hidden), and the user mustn't click anything except windws shutdown button. It is a service. When i write a Form1_FormClosing sub, it works only on Alt+F4 or CloseButton and doesn't work when the app is stopped from Windows Task Manager or whatever also.I need a way to execute sub when app is closed with taskkill (without /force) or a way to execute a several app on Winshutdown.

I am running Microsoft Visual Basic 2010 Express. I created a simple program that is nothing more than dozens of Windows Forms that are linked together by the various clickable buttons I put on each form. The program is like a "book" with several pages, and you jump to a specific page by clicking on specific buttons on the current page ("Windows Form").
My question is, how do I change my program so that when it is launched, instead of just 1 Windows Form opening, the program opens up several Windows Forms (of my choosing) automatically? In other words, instead of my "book" (VB program) opening "page 1," when I run it, I want it so that pages 4, 7, 8, 10, and 15, are "opened" whenever I run my "book."
Is there some code I need to insert into each Windows Form I wanted opened automatically when the program is loaded? Or is this a MS VB 2010 Express environment option I need to set?
I have a point in my .NET (VB) application at which the user is prompted to select zero to many documents to be printed, which are spawned off in separate new windowsThe list of documents selected is passed in from the previous page, pipe-delimited, as part of the querystring, which is then split to create a list of documents. My code iterates through this list, builds the new window's URL dynamically and then spawns the new window. For some reason I'm getting a maximum of two new pop-up windows, regardless of whether the user chose three or more, and the list is being populated fully and properly
