    - Code for finding manufacturer serial number for hard drive in C# Hi, If you understand the subject of my post that means you would know why i want this. Please dont give me the code for Volume number as i am talking about manufacturer serial number. I am working on C# and I know about win32_PhysicalMedia to retrieve the manufacturer serial number but that does not work for Win 2000 and I want something that works for Win 2000. Even if there is no solution in C# but you have something in C or J# that could help me that would be great too. Again please dont refer me to DiskId32 to get serial number as I have already spent alot of time trying to invoke it from C# , I tried wrapping procedures, but that does not work. So please I really need help and await a reasonable response from some genie out there. Tag: unhide window Tag: 87205

    - Running a winform from Scheduler I have a winform that starts from the scheduler. It performs a task, prints a status message on the screen on waits for the operator to terminate the program by clicking on the exit icon in the upper right corner. There is only one problem. When the program has terminated, scheduler thinks it is still running! Is there a way I can use an exit code that the Scheduler can pick up? Tag: unhide window Tag: 87204

    - dropdown filter in datagrid shows null-value Situation: Datagrid with two dropdownlists and some other boring values The list are: 'company' and 'project' What I was trying after picking a company then update the 'project' dropdown (filter the dataview that holds the values) with only the projects of that specific company. Well, that worked! Here is how I did this. Code: AddHandler dtContent.ColumnChanging, AddressOf Project_ColumnChanging Now the problem: it worked too good! If I do this in the a specific row, all the other rows (with other companies) the project-dropdown will display a null value. I understand WHY, but can someone tell me how to prevent this? I was looking perhaps for something with the nulltext-value (because the dropdownfield is showing the nulltextvalue) but can really put my finger to it... Tag: unhide window Tag: 87200

    - data access tier for win form Hi, I want to create a data access logic component for a win form app... I saw some example DAL components in web and groups. And I am surprised to see that all methods of DAL component examples return a dataset. For ex., we have a GetEmployeeById method on the DAL comp. And it returns a dataset containing a table with the employee info (fields) that we requested by Id. Is this a valid approach in designing a DAL component. I mean, my question is what happens when the user navigates from an employee to a different one. Every time a new employee is accessed, a new dataset is returned by DAL layer. Does this create a dataset inflation in the app.? What happens to old datasets then? Should they be disposed before navigating to a new employee... Then another problem is databinding. You can not use visual data binding facilities of Win forms because You are returned a new dataset each you request a new employee from the DAL... So, you have to databind in code every time the user navigate to a new employee record.. Is there anyone with experience on this subjects... Or do you know a good article about it? thanks in advance... Tag: unhide window Tag: 87193

But for a good view, I must display in the DataGrid CustomerName, ProductName (not CustomerID and ProductID, but In fact When I save the data to the table Income, I must save CustomerID and ProductID).

    - Problems when toggling between MDI child and owned child window I'm developing an Windows Forms application using VS.NET 2003 and .NET Framework 1.1 SP1 on Windows XP SP 1. The application is an MDI application where the user can make an MDI child form 'floating'. The child form is made 'floating' by setting its MdiParent property to null and then setting its Owner property to the parent form like this: Form form = ActiveMdiChild; if (form != null) { form.MdiParent = null; form.Owner = this; } If the user wants to make the form 'non-floating' again, the MdiParent property is reset in the child form like this: MdiParent = Owner; I experience two problems in the application: 1. When a child form is made 'floating' and then toggled back to 'non-floating', I cannot activate any of the MDI child forms by clicking with the mouse in the child forms client area (but it works if I click on the child forms title or border). I found a workaround for this in this newsgroup (thanks Ying-Shen Yu!). 2. If I set the MdiList property to true for the Window menu in the MDI parent, I get an unhandled NullReferenceException in Unknown Module after a child form is toggled to 'floating' and back and then dragging the MDI child forms around a few times. Have anybody else experienced these problems? Does anybody has a workaround for the second issue? Thanks! /Markus Tag: unhide window Tag: 87187

    - Form Security - Disable controls on a form As part of our security implementation, we want to disable some controls on some forms for some groups. This information will be kept in a database. when the form will load the security information will be read and controls on the form will be disabled or enabled depending on the security information kept in the database. After a control has been disabled on a form, we want to prevent any code on the form being able to enable the control again. Is there any way change those controls, so that they will not be enbaled again. Thanks, Mokles Tag: unhide window Tag: 87183

    - Putting custom objects on the clipboard All, It seems that there has been some discussion of this issue, but I can't find any real answers. How does one copy a custom object onto the clipboard and then retrieve it? I can do this with standard types and collections of standard types, but if I use a custom object the retrieved objects are always null. For example, given the following class: public class MyObject : Object { private string m_Name = ""; public MyObject(string name) { m_Name = name; } public string Name { get { return "MyObject:"+m_Name; } } } this code does not successfully copy/retrieve a MyObject object usign the Clipboard: MyObject myObj = new MyObject("Foo"); DataFormats.Format f = DataFormats.GetFormat("MyObject"); DataObject dObj = new DataObject(f.Name, myObj); Clipboard.SetDataObject(dObj, false); // Get it right back out IDataObject obj = Clipboard.GetDataObject(); if (obj.GetDataPresent(f.Name)) { MyObject stuff = (MyObject)obj.GetData(f.Name, true); if(stuff == null) MessageBox.Show("GetData failed for " + f.Name + "!"); else { MessageBox.Show("MyObject on Clipboard was: " + stuff.Name,"GetData successful!"); } } The GetDataPresent call is successful, but a null reference always comes back from GetData; the autoConvert param doesn't seem to have any affect. Do custom objects have to implement some interface or derive from some base clsss to make this possible? Must they be cloneable? Serializable? Any advice or suggestions?

    - MessageBox problem Hello, When I use MessageBox.Show(owner, ...) to display a modal dialog box the 'bong' sound is made immediately but the message box is not painted. For some reason, pressing the ALT key will cause the message box to appear. The application contains around 15 windows forms, spread over all the screen space on three monitors. I know that the message box is not being painted behind one of these forms as I deliberatlely left space on the screen where it would appear and it appeared when I pressed ALT, but not before. So it is not an issue with the Topmost property of the forms. Any ideas? The problem occurs with every message box in the application. I think it is related to the amount of painting going on since if I minimise all the forms in the application except the one that will display the message box it works. However, even when all displayed the forms appear to be repainting correctly so I have no idea how to correct this issue... Cheers, David Tag: unhide window Tag: 87162

    - winform fails to set size correctly! There must be something happening behind the scenes to "help" me, but I've got a real problem. I've embedded an AxWebBrowser directly onto a form, and I'm trying to set the size of the form to accomodate the contents. The width sets to a predefined number of pixels (816) correctly, but I can't get the height to work. The code setting the height is below. You can see what I'm doing is trying to set the form to be so tall that there's no vertical scrollbar. I do that by asking for the size of the scrollHeight, and growing the form so the client area is as large as the value of scrollHeight. But this code fails. The value of desiredHeight comes back with 7409, and the currentHeight is 293, for a delta of 7116 and a targetHeight of 7436. But when I set "this.Height = 7436" the form only grows to to 1036. That number is always the same. My screen resolution is 1280 * 1024. Does that affect the maximum possible size of a winform? Would I get the growth I need if I rendered this offscreen? The real reason I'm trying to work this out anyway is to do a screen capture and turn HTML into TIFFs, so doing it offscreen (or in memory) is the real target here, anyway. private void FitVertical() { MSHTML.HTMLDocumentClass doc = (MSHTML.HTMLDocumentClass)AxWebBrowser.Document; MSHTML.HTMLBodyClass body = (MSHTML.HTMLBodyClass)doc.body; int desiredHeight = body.scrollHeight; int currentHeight = this.ClientSize.Height; int delta = desiredHeight - currentHeight; int targetHeight = this.Height + delta; this.Height = targetHeight; } Tag: unhide window Tag: 87157

    - Has the EnableVisualStyles bug hit me? Hello All, I have a .NET application running on Windows XP. I have quite a few forms, some modal and some modeless. Once in a while we get a wierd exception in the application and most of the time the code is transferred to the top level 'ThreadExceptionEventHandler'. It is difficult to get the information on actual exception. Most of the time it seems to say "External component has thrown an exception' and the source of the exception object is 'System' Doing a bit of searching on the internet, I came across the known bug in EnableVisualStyles( ). I do not call the Application.EnableVisualStyles at all. but I do call Application.DoEvents (this was suggested as a fix somewhere) I tried looking for the comctl32.dll. In the System32 folder the dll has version 5.82. One of the articles on the internet said, XP uses 6.0 by default. Where would this dll be? I do get rounded corners for my form's title bar, does this mean that my application is using visual style? If yes where is it getting set? Is it the default under Windows XP (SP2)? Can somebody direct me to information which will lead to better understanding of visual styles and the related bug.

    - Maximising window using shortcut I created a windows form (using J#), set the BorderStyle to FixedDialog, and disabled the maximise box. All I wanted was that the user should not be able to change the size of the window. After my application was built, I created a shortcut to it. In the shortcut properties, I set the Run: property to "Maximised" from "Normal Window". When I started the application from the shortcut, it was maximised. I could neither resize the window, nor "restore" it (as expected). I think this behavior needs to be looked into. I feel that if an application's maximise button is disabled, then the shortcut should'nt be able to show the form as maximised. -- Sushovan, a crazy junior Tag: unhide window Tag: 87116

At run time the application start with a class (which ensures that there is only one instance of application), then control comes to login form and then comes to MDI parent form. I have some doubts and problems with GUI. 1. I am not able to disable the ControlBox of the MDI Children forms. I have set the following properties for all of the MDI child forms... ControlBox=False; MinimizeBox = False; MaximizeBox = False; I searched for the issue and found it as a big bug in DotNet on the following link ... http://www.dotnet247.com/247reference/msgs/33/169116.aspx Unable to remove the control box is messing up my application. 2. I read somewhere that if you don't set the project's starting object(at runtime) as MDI parent form, then MDI applications in DotNet create problems. Is it true ? 3. I have some common panel and functionlity. Right now that common panel has been replicated on each of the form. What is the best way to use these common panel and where to put the functionality. 4. How to change the the background colour of MDI Parent form. Right now I am using the following article but it is not changing the background colour of my form. The link is ... http://support.microsoft.com/kb/319465/EN-US/ 5. A strange issue .. Whenever I minimize the MDI parent form and restore it.back, the panels relocates in down direction. Each time I minimize it and restores back , it keep on moving in the downward direction. I don't have extensive experience of working in C#. Please forgive me if the issues seems to be silly and guide me. Thanking you, Rajat Tandon. A DotNet Learner. Tag: unhide window Tag: 87108

    - ToolTip : Setting the pop-up location. With the [ToolTip] control - I'm wondering if there is a way to explicitly set the location that it pops up. From it's ref docs I can't see a way to set a location - and I'm wanting to have different tool-tips popup based on mouse activity within the bounds of a single control. Is this possible - or is there perhaps another control that can be used for pop-up tooltips? Many thanks everyone. === Phil Tag: unhide window Tag: 87107

    - Embedding a form into a panel control I am embedding a form into a panel control using pnl.Controls.Add(form); This works pretty well, however there is one problem. The panel can resize, so there are cases when the panel size is smaller than the form embeded in it. The framework handles this problem by showing only a piece of the form that fits in the panel. Is there a way to add scroll bars to the panel so that the user can view the entire embedded form without resizing the panel? Is there any piece of code that handles this whole situation? Thank you Cezar Mart Tag: unhide window Tag: 87104

Hi all,

how can I set an app's main window visible from an other application? My
problem is, that I know only the handle of the other app's main process,
because the application's main window is set to hidden, so it doesn't
have a mainwindowHandle, so I can't send a message to it.

Any idea?

Thank's in advance,

Tamas Meszaros

Hi Tamás,

You can use Form.FromHandle (...)
