View 4 RepliesI am at the form/application stage, and now working on my final project. I know how to open an application from the form, but I want to open the app within the form. I already have my web browser on one form, and button command that gets me there. I also want to run a special program that I have already created in the command window on the form that I have. I have the form ready, the command that I click to open the cmd.exe but, now it I cannot get it to run in the form, ie. a panel. At least that is where I think it should run.
my panel is called pnlcommandwindow, and I have it visible:false until I click the button. It opens with cmd.exe and command.com. But, I want the same window that is opened when I run a program in VB command window.
In the command button or the panel or another box?
I am writing a Class Library for a GIS Windows application. The class has a form that I open when I load the dll command in the application. After the form opens the form moves to the back of the GIS Windows application, and I want it to be in front of the GIS Windows application all the time. How can I do this?
View 1 Repliesnot quite sure why this is happening but I am just debugging right now and the buttons I am using are opening the wrong forms, I have made sure of the form names, button names etc and it looks all good but specifically the btnPrintReport is opening up the form enterAuditForm while btnProcessAudit is opening printAuditForm instead of their correct ones.
Here's my code, it is rather simple. The reason why I am using a separate sub as my btnPrintReport is because I am using that also on the baseForm's OnLoad Event, which again is also opening the wrong form.

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))."}
I only managed make the form always on top. But what I want is when the form is on top, user cannot access the other application in the windows.
For example : Some messagebox won't let users access the other application until the users hit the OK button.
Is there any switch that will allow you to open an application over all the other currently open applications? My problem is getting Explorer to open over all the other currently open applications. Right now, it only opens in the background......
View 5 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?
View 9 RepliesI 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 am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel

I want to open a VB.net form using a ThreadPool with a maximum of 10 threads. I need to do this because, the form should open based on a live event and i need atmost 10 forms on the desktop at a time. If i open the form on every live event without using a ThreadPool, the desktop will be floaded with many forms. I am using QueueUserWorkItem method of threadpool to queue a method which opens the form. In this queued method, there is form1.show() statement called. But after displaying the form, this method finishes execution and again we have 10 threads available in the system. I somehow want to either keep this method running so that 1 thread is occupied or i want to keep the thread alive till the form1 is closed by the user. I want the 11th form to appear on the desktop, only when any of the existing forms out of the 10 (already on desktop) is closed.

View 2 RepliesI'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:

frmSettings.Show()

The .Show() command is not available and is not proposed by intellisense.
Of course I've added a reference to System.Windows.Forms
I thought this would be easy but for some reason it's giving me a rough time. I have a windows form with three equal size panels on it. Each panel takes up about 1/3 of the window width, less some inter-panel spacing.
The effect I want is if the user stretches or shrinks the form the panels maintain their relative 1/3 width and spacing, similar to how divs on an html page would size as the browser window is sized.
So I anchored the left panel to left, top and bottom, the center panel to top and bottom, and the right panel to top, bottom and right. This works fine in keeping the left and right panel anchored to their respective sides, and all panels now stretch with a form height change.
So in form resize I adjust the width of each panel to form.width/3. As expected this is close but does not account for the inter-panel margins I want to preserve and the form border width.
I played around with various constants and noting I do gives me the desired effect.I'm sure there is a pretty straight forward solution to this but I can't seem to find it.
I have a basic three form application. It doesn't seem to close after navigating through forms. If I were to open the application, and the main form is displayed. If I press the X button, the application closes fine(Goes from processes) If I were to open the application, and then navigate from the main form to another form using me.hide & form1.show, and press the red X on Form1, the application again, closes fine.

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

I need to open a form on top of the form of another application, that is, making the other applications form its parent. The title on the applications form can change, so searching for the form by name won't work.

I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
