    - Problem loading a windows form. Please help. I have created a .net windows form in vb.net and compiled it as a .dll. I then register the .dll with regasm. I then call the form in a vb 6 application using the following code. dim c as object set c = createobject("LaborOrg.form1") c.show It works great on my developer machine. I place the .dll and the .tlb on the client's server and regasm the dll. I check the registry and it shows LaborOrg.form1. When I click the button to display the form nothing happens. The app and the winform dll are both on the server and I am trying to run it from the server. I do have .net framework on the server. Any suggestions?

    - Form's KeyDown delegate not called when in DropDownList ComboBox I have a form with a delegate set up for the KeyDown event. I have set KeyPreview=true and the delegate is called correctly whenever I press a key, except if the active control on that form is a DropDown ComboBox. If I change that ComboBox to be DropDownStyle=ComboBoxStyle.DropDowList the delegate fires when I press a key in that control, as I would expect. The problem is I don't want to restrict the ComboBox to a fixed list of options. The user needs to be able to select, or type their own option. I have reproduced this in an extremely trivial app - one form, two comboboxes, one delegate, and no databinding etc. Does anyone know whether I could be doing something else that has created this problem, or whether this is a known bug? I have searched but can't find a post that seems relevant. Thanks, Scott. Tag: Data from Web Browser control back to the windows form Tag: 73501

    - Empty value in binded combo box Hi all. I have to display a dialog adding a new DataRow into the DataTable (say, dtMain). One field (say, "Location") of dtMain is a reference to the "ID" field of the other table (say, dtLocations) and I want this field to be shown on the dialog form as a list of values of all "Name" fields of dtLocations, not as a list of "ID" numbers. I bind as follows: // Making referenced data displayable by their names dlgEditor.comboBoxLocation.DataSource = dtLocations; dlgEditor.comboBoxLocation.DisplayMember = "Name"; dlgEditor.comboBoxLocation.ValueMember = "ID"; The other requirement is that initially I have to display the empty Location field on the dialog form. dtLocations does not contain a row with empty "Name" value. Of course, I would be glad to do dlgEditor.comboBoxLocation.SelectedValue = "" or something like this but I get a natural exception. This is what I do. Before I show the adding dialog form, I add the temporary DataRow into dtLocations with empty "Name" field: DataRow rowWithEmpty = dtLocations.NewRow(); dtLocations.Rows.Add(rowWithEmpty); dlgEditor.comboBoxLocation.SelectedValue = DBNull.Value; // or "" Then I show the dialog, everything looks fine. After the dialog isclosed, I delete this temporary row from the dtLocations: dtLocations.Rows.Remove(rowWithEmpty); This works (the only thing I don't like is that this temporary empty value is available among combo box values) but I am not sure I did what I had to do in this situation (I am a newcommwr in .NET). Is there any smarter decision? Thanks, Dmytro Pavlov. Tag: Data from Web Browser control back to the windows form Tag: 73497

    - Best Place To Store Personal Information Hi to All, I'm developing an application in VB .NET. I have a question: what is the best place to save personal settings of my users? I mean, when a user uses my application, it can create a personal profile (e.g. last files opened, custom settings, etc...). What is the best place to save them? At first, I thought to save them in the registry, in the CURRENT_USER section, but I'm not sure every user can have read/write access to it. What do you suggest? Where can I find more information?

    - Using LogonUser to authenticate a user Hi, I need the ability to authenticate a user within my application against a specific domain. The machine where the application is running might be part of this domain, another domain or no domain. I am trying to use the LogonUser API which seems to work fine when the machine is part of the target domain, but it does not work when the machine is not part of a domain. The ultimate goal is that once the user authenticates, I impersonate the user and connect to a database using SSPI. Is there some way that I can achieve this functionality? Thanks.

    - Coping in .NET I have a ListView control with several columns and rows worth of data. What I wantto be able to do is to allow the user to hit copy and it will copy this information to the clipboard. Then I would like the user to be able to open up any of the following application; Excel, Word, PowerPoint or WordPad and be able to paste the data into these applications. In Excel it should obviously paste the information into the different columns and rows. In Work and PowerPoint I would like to be able to create a table put the information into the applications this way. Ideally pasting into WordPad would also work and just provide the data, in neat format, like tab between the columns and enters between the rows. Basically I want it to act similar to if you copy information from Excel and try and paste it into these other applications. Tag: Data from Web Browser control back to the windows form Tag: 73450

    - Slow Form Controls Drawing Hi together, my first test with C#.NET (MS Visual Studio 2003; .NET 1.1) was very disappointing... The display of a dialog looks like in former days... so slow! Yes I know the JIT compiler ... but this is not the problem (it occurs even if you display the dialog more than once). The display process of painting the controls is very slow (even with a 2Mhz PC)! I searched the whole newsgroups and can't find any other user who has this problem... and this I can't understand. I tried it meanwhile on 3 different PCs (all about 2 MHz and about 512 MB). Here my (very simple) scenario: a. I simply created a new C# windows application and defined the main form as MDI container. b. I added a main menu which contains one option for displaying a dialog form. c. I created the dialog form and put only 5 controls on this form (one group box and 4 textboxes). This means no special overloaded user controls! d. So now let's start this "big" application. I select the menu option and the dialog appears (ok...) But if you look how the form will be displayed you can see that first of all the form will be drawn, and at all locations where the controls will be displayed, a rectangle with the (dark gray) background color of the MDI form is shown through. After this the controls are drawn. Ok, this goes fast but nevertheless you see these dark gray rectangles for a short time and this looks very unprofessionel... If you rebuild this scenario with former C++ or VB6 applications, it's not the case. First I thought there are different window styles for .NET forms defined (e.g. difference with WS_CLIPCHILDREN or WS_CLIPSIBLINGS) but the "Spy" tool shows me the same settings... This means there must be different implementation for erasing the background or drawing the controls????? Is there no .NET developer which is annoyed by this behaviour???

With a lot of error during link - I fixed this - and we are now using Managed Code. I inserted a new Windows form into the application - how can I use this class - or form - in my original code? It's a simple "click on button (in MFC) and get the new Windows Form". THere are no classes as I'm used to. Just add the class into the cpp file and do a DoModal to that class.

    - Data Validation Hi there I am trying to implement very simple field data validation: I have a form with one TextBox (textBox1) on it. To validate user input I implemented Validating event handler (usual stuff) private void textBox1_Validating(object sender, System.ComponentModel.CancelEventArgs e) { string error = null; if (textBox1.Text == String.Empty) { e.Cancel = true; error = "need text here"; } errorProvider.SetError((Control)sender, error); } My problem is that when I click on formâ??s control box close button I donâ??t want any validation to happen as Iâ??m going to close the form. If I had my own â??Closeâ?? button on this form I could set itâ??s CausesValidaton property to false and the problem would be solved. Are there any properties of the form that I can set to avoid validation? Any suggestions? Thanx Tag: Data from Web Browser control back to the windows form Tag: 73437

I've seen a number of articles about a control being "owned" by the thread that created it, so, my question is, is what I'm trying to do even possible? Is there some other way I should go about it?

    - Control designer for custom user control property I have a control that I've created and it exposes several formatting properties through a "Format" member. I've created a control designer that gets activated in Visual Studio through a designer verb. The designer gets activated and is able to read and write to the special Format property of my control. However, when I run the program all my changes are lost. My Format property doesn't show up in the properties area of VS for the control, but I know my property has been changed because when I reopen the designer it reflects the changes. I suppose that this behavior makes sense because Visual Studio doesn't know anything about my Format property which I create from a custom class. Do I need to provide some special serialization routines in my designer to save my changes in the form? If so, how do I go about doing that. I have a book that taught me how to create the designer but the only properties it ever changes in its demo are ones that show up in the properties window. Thanks for the help. - Rhy Tag: Data from Web Browser control back to the windows form Tag: 73429

    - 100's of UserControls to dynamically load ... How? Is there are equivalent activity in .NET Windows to MyControl =LoadControl("NamedContol.ascx") ? I need â??loadâ??, add to a ControlsCollection a particular UserControl based on a run-time XML stream. For example by picking off attribute: UseVisualControl=â??SomeUserControlâ?? There will be 100â??s of such UserControls available for the stream to request. From this static, design-time snippet: Dim MyUserContol As SomeUserControl = New SomeUserControl Me.Panel1.Controls.Add(MyUserContol) How can I do this dynamically, creating the requested â??SomeUserControlâ?? on the fly WITHOUT a gigantic case statement: Select Case UseVisualControl Case â??AUserControlâ?? Dim MyUserContol As AUserControl = New AUserControl Me.Panel1.Controls.Add(MyUserContol) Case â??BUserControlâ?? â?¦ Dim MyUserContol As BUserControl = New BUserControl Me.Panel1.Controls.Add(MyUserContol) Case â??CUserControl â?¦ Dim MyUserContol As CUserControl = New CUserControl Me.Panel1.Controls.Add(MyUserContol) Beyond this â?¦ I would like to be able to catalog the UserControls available as part of the XML editing / creation. Speaking to the user â?¦ For this node, here is a list of UserControls you can select from (to set UseVisualControl=â??SomeUserControlâ??). Is there a way to catalog them programmatically?

    - Problem w/ .RESX files (MR) I've created a custom control. And now I've something that prevents me from using the designer to layout controls on my custom control. I tried deleting the .resx file, thinking the VS would just regenerate it, but did not. Here's how I got the problem: I created a new user control. I called it BaseControl. I created another new user control. I called it DerivedControl. After VS generated the .cs file, I changed the base class to BaseControl. EG: public class BaseControl : System.Windows.Forms.Control public class DerivedControl : BaseControl Now I am unable to add controls to DerivedControl using the designer. I have to manually create the code in .cs file. This gets really hard to lay things out. So, what I can do so that I can use the designer?

    - namespace design help Hi there, I am designing a application that has many different parts to it i.e. Database read and write, Encryption classes, printing functionality. etc etc I have created a standard namespace i.e. mycompanyname.myapplication Is it better to then create a new name space for database and encryption parts i.e. mycompanyname.myapplication.encryption mycompanyname.myapplication.database or is it better to stick everything in one name space?? I am also thinking about designing some seperate dll's (modules) for the app, what naming convention should i use for the name space here i.e. just mycompanyname.myapplication or drop down to mycompanyname.myapplication.mydllFunctionality Any help or guidance would be gratefully appreciated Thanks Ian Tag: Data from Web Browser control back to the windows form Tag: 73416

    - PrintDocument and PrintPreviewDialog I have a PrintDocument which is passed to a PrintPreviewDialog. The format looks exactly the way I want it when the PrintPreviewDialog comes up. When I click on the printer icon and actually print it, the paper comes out with everything moved down approximately 1 inch. I've tried printing on several different printers and types of printers (laser, ink jet, etc.) Is there something I have to do besides pass the PrintDocument to the PrintPreviewDialog to get this to work right? Dim pp As New PrintPreviewDialog pp.Document = pd pp.WindowState = FormWindowState.Maximized pp.ShowDialog() (pd is my PrintDocument) Thank you, Duke duke061720040933 Tag: Data from Web Browser control back to the windows form Tag: 73412

    - ANN: Give your .NET Windows applications and controls resolution independence. Hi All, I've just released v1.0 of BKResizer. BKResizer changes the size, location, and font size, scales the background and foreground images of controls as they are resized, without requiring you to write ANY code. It handles controls added at runtime, docked controls, anchored controls and any control nested in a container; docked or otherwise. Control developers can use BKResizer to add resolution independence to their own controls! BKResizer enables you to change the size, location; font size, scale the background and foreground images of controls at runtime and it will keep everything in proportion. BKResizer will even remember the last size and location of any Windows Form. BKResizer enhances each control's capabilities by allowing you to select how it will be resized through the control's very own properties without requiring you to write ANY code. For instance, increasing rendering speeds and reducing flicker through double-buffering, is now just a click away! BKResizer's Test Mode enables you to modify your enhanced controls using the familiar property grid in a runtime environment. This is done without having to modify your code. You can then choose one or more of the design changes made in Test Mode, apply them in the Visual Studio designer and compile just once! BKResizer enables you to manage control alignment, by introducing you to Virtual Bounds and Anchors. Combining Virtual Bounds and Anchors with Test Mode enables you to quickly handle your resized layouts without requiring re-design of your current user interfaces! These are just SOME of the capabilities offered by this powerful feature rich .NET resizing component. BKResizer was developed in 100% CLS compliant C# code. It contains thorough documentation in .CHM (Compiled HTML Help) format with tutorials and examples written in both C# and VB.NET for your convenience. Enjoy!

Hi,

I would like to know what's the best way to capture data from a page
inside a web browser control into the windows form.
The data inside the web browser's page is in whichever way i want it to be
since it's generated.

Thanks in advance,
