VS 2010 Interop And Modal Forms?
Feb 9, 2012I have a .NET application that calls a method in a COM component to show a dialog. Unfortunately, you can't pass the .NET form to the COM component to set the owner form without a type mismatch:
_ComForm.Show vbModal, _DotNetForm
So, what that means is the form is displayed without a parent form. The problem is, if the user launches the COM form and then while the dialog is shown, clicks to another application and then returns to my application, the COM form is now behind the .NET owner form and most users won't know how to find that window. Is there any way around this?
Showing Windows Forms From DLLs?
Oct 2, 2010I'm trying to show a Windows Form from a DLL file - it's added to the application's refrences But I can't call the Windows Form from the DLL, I tried to make a function that shows the form but when I try to call that function in my application it says: Reference to a non-shared member requires an object reference How can I show the form? I'm tried to use this method: (it's in the DLL's form)
Public Sub Open()
Dim Instance As Windows.Forms.Control = Me
Instance.Show()
End Sub
Managing Modal Forms Location
Oct 3, 2010I've got a "Loading" form which I display as a modal form when doing lengthy processes. I'm using the below to keep the form centred within the child form performing the process. However, when minimisingmaximising the "Loading" form appears before the parent making it look a little unprofessional. Anything I can do about that (Delay it appearing or attaching it in a different way)?

Modal Dialog With Multiple Forms
Jul 21, 2009Is there a way to specify what forms are Locked when opening a Modal Dialog? I want to have a specific form available even if a Modal dialog is opened. The form in question is a child form (Accessible from the Windows application bar), that is created from the main application form. The Modal Dialog should only lock the main application form, and not the secondary window. Is it possible to make a secondary form independent from the main application form?

View 19 RepliesDivide Project Into Smaller Entity (dll) Or Convert 10 Forms To 10 Dlls?
Jan 21, 2011Let say I had a project contains 10 forms and 10 reports and typed dataset (xsd)I am trying to divide my project forms into dlls, so when the client had a problem or asks for modification in single forms, I had to build the project all over again and the exe size will be large.
in my current project, the exe size is 4.8 MB, and I am working with customers by internet and remoting, so every time I make small changes (change the back color of textbox in one form) I had to rebuild and send the whole 4.8 MB to the customer. And not forgetting the increasing size of the exe with time.I know that converting my project to class library and built it will convert it to dll, so I had to create a second project to manage it.
1 - Can I convert 3 or 4 forms / 10 forms total in my current windows application project to dll?
2- What is the best recommended method to divide the project into smaller entity.
DLL Import - DLLs Were Re-compiled As 64-bit DLLs And They Still Don't Work?
Apr 6, 2010I am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.

Force Visual Styles When Using .NET Forms Interop From VB6?
Jan 4, 2011I have created a VB.NET Class Library that exposes some COM Interop sub routines. These in turn show various forms that are contained within the Class Library. When the forms are shown from VB6 they do not inherit the visual styles of the operating system and act like VB6 controls.
I gather that this probably by design but is there some way to force/control visual styles manually in the .NET assembly? I would imagine that if I use a manifest in my VB6 app then everything will use the correct style but I would like to be able to control this myself if possible because we are using 3rd party controls in VB6 that do not require a manifest.
VB6 - Video Series Is Focused On The Interop Forms Toolkit ?
Jun 10, 2010Visual Basic Interop Video Series This how-to video series is focused on the Interop Forms Toolkit and working with Visual Basic .NET and Visual Basic 6 together. The Interop Forms Toolkit allows Visual Basic developers to migrate their Visual Basic 6 applications over to .NET using a phased migration strategy. Instead of having to convert the entire VB6 application at once, the toolkit enables .NET Forms and User Controls to run directly in Visual Basic 6 applications so that you can build the pieces that you need over time.
Download the Code: Videos 13
You will need: Visual Studio and the Interop Forms Toolkit 2.0 in addition to Visual Basic 6.0

.net - Form Load Event Fires Twice Using Interop Forms Toolkit?
Sep 18, 2009I've been following a codeproject article on using the interop forms toolkit (basically a way for developers to slowly upgrade their VB6 projects to .net by allowing .net components run in VB6)

While the .NET form is working fine in all other testing projects and environments, I've found that the Form_load event is actually firing twice once it's in executing in the VB6 runtime.Not only annoying, its forcing my initialization code to execute twice (causing all kind of problems on the second run).

Forms :: Displaying Forms Automatically On Different Monitors
Jun 13, 2012I have created an application that uses two forms one is displayed on a touchscreen and is a basic input form, the other is displayed on a large display monitor and is basically an information form, both displays are connected to the same pc. The program works great I have just one annoyance is if the program is restarted it displays both forms on the touchscreen and I have to drag the information form onto the big display. Is there a way to specify on load that each form gets displayed maximized on a certain screen so I don't have to drag one form onto the correct screen?

View 3 RepliesForms :: Displaying GIF Image That Says Please Wait
May 4, 2011I have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.
Forms :: Displaying Objects On PropertyGrid
Mar 31, 2009I am having a problem with objects that have other objects as properties on a property grid. Now when I display the object clsPropsFrame on the property grid, everything shows up as expected, except when I try to edit the x, y, or z of location which is of type clsPropsVec3, it ignores the change. What's strange is that when I type the vector in as a string (like "0, 16, 0"), it changes.
I have the following
'//////////////////Object Component///////////////////////////
<TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class clsPropsVec3
Inherits ExpandableObjectConverter
Private refvec As TV_3DVECTOR
Public Sub New()
[Code] .....
I noticed that when I changed a component of clsPropsVec3, the property change in clsPropsFrame does not get executed. I tried making it fire of an event when a component is changed in clsPropsVec3, with the following additional
Public Property X() As Single
Get
Return refvec.x
End Get
Set(ByVal value As Single)
[Code] .....
But for some reason it ever fires off the ValueChanged event. So how can I make the sub properties of clsPropsVec3 work?

Forms :: Displaying Text Inside A Form?
Jun 29, 2009actually i'm trying to write a small program for my project's presentation. i created a form with buttons, each time i click on a button, i want a text loaded from MS word document to be displayed inside the form.
i thought about dislaying the text inside a label or textbox, but the problem is that the text doesn't preserve its state, i mean colors and fonts which are defined in the MS word document, it just displays everything in black color, small size..etc, even if i change the properties of the label in color or font, thoses changes will be applied to the whole text.
is there any control who can display the text loaded from a MS word coument with its colors and fonts which are already defined in the word document, or there any solution to do this ?

Oct 24, 2010Just moved a .NET 2.0 App from VS2005 to VS2010 and noticed that now when a window containing a WebBrowser tries to retrieve a pdf it thows out an error (unknown file type System.Byte[]). This would usually indicate that Acrobat Reader has not been installed - but open up IE9 and enter the link into the address bar and the PDF displays in the browser without any incident!
Should point out that the app created in VS2005 and installed on Win 7 (actually Server 2008 R2 in 'Workstation Mode') has the same issue.. All works fine in XP and below... Do seem to remember this on a Vista box, but put that down to Acrobat not being installed!
