    - Problem using API CreateBitmap function and keeping transparent co I have a C# DLL that loads a bitmap object from a PNG file. Thanks to Bob Powell's advice i managed to access the Bitmap data using the lockbits method and then call the Windows API function CreateBitmap successfully. Then the DLL provides a COM interface which returns the handle to the bitmap created using CreateBitmap function. The problem is that the initial bitmap has a transparent background color, and when using the CreateBitmap function, the bitmap seems to loose this color, which is then replaced by black (maybe something to see with ColorPalette). Furthermore, the createdbitmap is a 32bit bitmap so the alpha layer which contains transparency informations should be the same. So i don't know what i missing or doing wrong. here is the code that creates the bitmap : Bitmap bitmap = (Bitmap) Bitmap.FromFile(@"C:\tmpicon.png"); BitmapData data = bitmap.LockBits(new Rectangle(new Point(0,0), bitmap.Size), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); IntPtr HBITMAP = CreateBitmap(bitmap.Width, bitmap.Height, 1, 32, data.Scan0); NB : I also noticed that when opening the PNG file with MS Paint, the transparent color is replaced by black, whereas opening it with Photoshop or Windows Picture viewer, the transparency is visible. Can't explain this... I'd like to understand what im missing to keep the transparent color on the created bitmap. Thx for any help. Tag: Memory taken by an object Tag: 92237

    - ToolStripContainer and MDI applications? Hi, I have an MDI container form (Form1) that has a MenuStrip and a ToolStrip embedded in a ToolStripContainer. Form1.MainMenuStrip is set to MenuStrip1. The "Content" part has a ToolStripPanel docked to Fill the entire space. I guess this is a pretty normal setup. The problem is that all Mdi childs are invisible. They open up under the ToolStripContainer, making them invisible. What am I doing wrong? I open the Mdi childs like this: Form2 frm = new Form2(); frm.MdiParent = this; frm.Show(); Thanks a lot for your help! Tag: Memory taken by an object Tag: 92235

    - MouseUp event "falls through" FileDialog and activates control underneath Hello, In my app I have a UI control that responds to MouseUp events and opens a FileDialog. If an item in the dialog is double-clicked (instead of clicking on it then clicking OK) AND that item is over my UI control, the final MouseUp of the double-click is registered by my control and its handler is called, opening the FileDialog again. The events happen in this order: MouseDown MouseUp Dialog Opens Double-click in dialog Dialog closes MouseUp DialogOpens, etc. I'm looking for suggestions on how to correct this. I've tried removing the MouseUp handler when the FileDialog is opened, and adding it beck when it is closed but that doesn't work; it still gets called. I've tried looking for a way to "eat" the MouseUp but haven't found a way that works. For example, purging the event queue or marking the event as being handled/ignored. So, any suggestions?

    - RichTextBox + DragDrop = Buggy? Hi Consider this simple scenario: richTextBox1.AllowDrop = true; richTextBox1.DragDrop += new DragEventHandler(richTextBox1_DragDrop); richTextBox1.DragEnter += new DragEventHandler(richTextBox1_DragEnter); richTextBox1.Text = ""; private void richTextBox1_DragDrop(object sender, DragEventArgs e) { richTextBox1.Text += e.Data.GetData(typeof(string)) + "\n"; } private void richTextBox1_DragEnter(object sender, DragEventArgs e) { if (e.Data.GetDataPresent("UniformResourceLocator")) e.Effect = DragDropEffects.Link; } When dragging a URL from IE and dropping it on the RichTextBox everything is fine. But when also clicking in the control, the drop event is activated once more!? That can't be right? I have only found this to happen in the RichTextBox. Is it a bug in this control or am I forgetting something? /Andreas Zita Tag: Memory taken by an object Tag: 92226

    - Installing Merge Modules from C# Windows Form Application (not using a setup and deployment project) Installing Merge Modules from C# Windows Form Application (not using a setup and deployment project) Hi, Currently, we have an InstallShield project that creates a setup.exe that only installs 20 or so merge modules. It does nothing else. We then have our own custom, C# Windows Form application that installs our software applications. It does this by copying files, creating registry keys, etc. So what I'm trying to do is get rid of the separate InstallShield setup.exe. We want one setup application that installs both the merge modules we need and our software applications. Is there any way to run/install merge modules from a C# Windows Form application? We are not and cannot use a Setup and Deployment Project to do this. Thanks. Tag: Memory taken by an object Tag: 92216

    - detecting the change in the cell of a datagrid Hi I am implementing DataGridTextBoxColumn in my Datagrid. I would like to find out when the data in a cell belonging to this column style is changed. I would like to format the contents say for instance to a currency if the contents of the textbox are of numeric type. I modified the following in the Commit function Protected Overrides Function Commit(ByVal cm As CurrencyManager, ByVal RowNum As Integer) As Boolean ' ' Parse the data and write to underlying record. ' Me.HideEditBox() ' return focus to the DataGrid control Dim box As DataGridTextBox = CType(Me.TextBox, DataGridTextBox), Value As String ' Do not write data if not editing.

Try If ValidateContents(TextBox.Text) Then Value = FormatContents(TextBox.Text) Else return false ' to retain the old value This is the problem. End If Catch Return False ' Exit on error and display old "good" value. End Try SetColumnValueAtRow(cm, RowNum, Value) ' Write new value. End If Me.EndEdit() ' Let the DataGrid know that processing is completed. Return True ' success End Function Commit function is being called twice when I have the return stmt.

    - changed Property of Public Control a Designtime on UserControl disapears! Hi, I'm having some weird behaviour, and I can't find any solution to this. I made a UserControl (uclCommands) which contains a Toolbar (ToolBar1) with Modifiers = Public. I put this usercontrol on my form and call it Ucl1. In the Property Window in the Windows Forms Designer I change Ucl1.ToolBar1.ButtonSize to a bigger value. Everything goes fine: The buttons get the larger size. but after I compile, the ButtonSize gets again the original size..... Does anybody knows why this happens, and what I can do about it? I really need this because my Usercontrol must have different sizes in my application. I tested this with Visual Studio 2005 beta 2 and VS 2003: Both the same behaviour...

If the control is loaded from the server then AppDomain.CurrentDomain.FriendlyName contains the URI of the server that the page is from. If my control is loaded from the GAC on the client machine then the FriendlyName is "Localhost". Is there a way to get the URI from within the control.

    - Datagrid row selection In windows explorer you can select multiple files using combinations of ctrl and shift clicking, then if you click and hold the mouse button on one of the already selected files you can drag all the selected files to wherever. I'm trying to reproduce this kind of behavor in the datagrid, but the problem is that when I click and hold the mouse button on an already selected row all the other rows get cleared and only the clicked on row is selected! I thought I could get around this by keeping track of all the selected rows, intecepting the MouseDown event on an already selected row and then restoring all the rows that are supposed to be selected using DataGrid.Select. However, this doesn't seem to work. It appears that the rows get cleared *after* the MouseDown event and, therefore, after my code to restore the selected rows. This is very frustrating! Does anybody have any ideas on how I can make this work? I have to restore the selected rows while the user still has the mouse button down so that they can drag them.

    - System.InvalidOperationException: Failed to load ImageList I have seen talk of this around but none of them seem to be exactly my problem.

I looked into this futher and noticed that the ResEditor can't even open the .resources file generated when I compile the program. It fails to load the imagelist resource. What is the problem? It is as if the resource compiler is not serializing the imagelist out correctly. I already tried to do a repair install of Visual Studio 2003. I have a Windows XP SP2 system on a dell laptop.

    - MessageBox-Like Focus in a Custom Form? I am writing a Windows Forms application that manages "Project" content on CD-ROM and DVD media. If the end-user wants to Open a "project", I have to prompt them to insert the media if it not already in the drive. Legacy media contains a heinous Autorun routine that I must intercept. I can do all of this without problem. However, I can only intercept the Autorun event if I am the "Top" Form with Focus. So, I want to display a message box with Cancel and Retry buttons that also contains my custom code for intercepting the Autorun event. How do I create a form (or a derived message box) that incorporates my custom code while maintaining the insistent modality of the MessageBox? Are there some simple properties that I can set on a normal form or simple way to inherit from the standard MessageBox and add my own code? Any advice or suggestions are greatly appreciated.

    - Problem accessing VB6 .OCX file from VB.NET Hello: I am trying to access a VB6 OCX file (with many important methods in it created by me) using VB.NET. Let me tell you what I have done to access the methods. I started with registering the OCX file using regsvr32 and registering the ocx file. I tried to create an object using the NEW keyword but was giving me an error saying that the method NEW was private and I cannot access it outside. So I upgraded the old VB6 project to .NET and it created a new .dll file with a "New" method in it. So I could declare an object for that. But whenever I start trying to access any methods in the OCX file I get an exception saying "InvalidActiveXStateException". If I debug step by step, I dont get that exception and but I dont get correct results from the methods. "Register for COM Interop" option is selected in the properties and I also registered the new .dll file using regasm.But the methods still donot work. Please Help Thanks in Advance.

    - Form designer fails to load inherited form I have a base form with a few controls, some methods, and some properties that I inherit from to create three different form classes (in a VB.net 2003 solution, in a lib project along with program and deplyoment projects). When I first wrote this, all worked just fine. I created a new inherited form (using Add inherited form ...) and immediately the newly created form plus any existing forms that inherit from the same base form no longer display but give the error message, "An error occured while loading the document. Fix the error, and they try loading the documen again. The error message follows: Object reference not set to an instance of an object." I assume that the form designer has failed somehow when attempting to draw the form in the design mode. The newly created form never displayed at all. The base form (and others that don't inherit from it), however, display without error. Removing the newly created inherited form from the project and deleting it entirely has not fixed the problem; now I get this error with any of the inheriting forms. Yet, the application runs just fine. I tried the trick of closing all [Design] tabs, and also completely restarting VS with no luck. I ran into this once before and solved it by recreating the base and inherited forms from scratch, a time-consuming excercise that I don't wish to repeat. I am able to recreate a form inheritance example in a separate solution with no problem, as well. Does anyone have a fix or some ideas of what to look for?

    - Disable drag & drop outside of control Hi All, I am working on a VB.NET app that has multiple windows. I am using drag & drop to move items within a list on the same form, but I want to disable drag & drop between the 2 windows. I thought I could disable the drag & drop when the DragLeave event was fired, but alas, DragLeave only uses System.EventArgs, so I can't set e.Effect to None. Short of prefixing my dragged items with the window number and just doing a check when entering another drop-able control, is there any way I can disable the drop? Thanks in advance!!!

    - How to draw text that will fill a panel(form, etc.) Hi, I would like to draw centered text that takes up the entire paintable area of my form. I know how to use a StringFormat to center the text both horizontally and vertically. What I don't know how to do is choose the correct height (and width?) for my font. When the form is resized the font size (and width?) will have to be updated. Thanks, BT Tag: Memory taken by an object Tag: 92139

    - How to call GDI CreateBitmap function using C# Hi, I do have a Bitmap object in a C# application, i would like to create a bitmap using the GDI function CreateBitmap which could return me a valid HBITMAP (Dont want to use the GetHBitmap method which returns a 24bits bitmap which will loose any Alpha informations like transparency). The declaration for the function will probably look like this : [DllImport("gdi32.dll")] public static extern IntPtr CreateBitmap(int nWidth, int nHeight, uint cPlanes, uint cBitsPerPel, short[] lpvBits); But i have no clue how to provide the parameters CBitsPerPel and lpvBits, and what they do correspond to in the .NET Bitmap object. Any idea how i could call this function properly ? Thx. Tag: Memory taken by an object Tag: 92136

    - common inheriting class for list controls not satisfactory Hi, I want a common class through which I can use the common functionality provided by the combo box and listbox controls. To elaborate what I'm saying: I wrote a function in which I use the following: 1 - BeginUpdate 2 - EndUpdate 3 - Items collection 4 - items.clear() method above four are avilable in both the combobox as well as the listbox (also listview and maybe some others). I pass a listbox to that function. Now I want to use the same functionality for a combobox also, but cant do that. If I take ListControl as a parameter, which is the base for combo and listbox, it doesnt have a "items" collection neither the "*Update" methods. If I use the ObjectCollections class, they are specific to the listbox and combo as they r inner to both of them. Is there any way I could do this. I dont have the options of extending/inherting from these combo or list control and make my own stuff and pass to this function. Regards, Abubakar. Tag: Memory taken by an object Tag: 92132

    - Combobox paint problem Hi all, I've got a windows app in development - one of the forms has a tab control on it and one of the tabs has a combo box on it. On the first entry to said tab the combo box displays correctly. Leave the tab (to another tab) and return, the combo refuses to paint itself. If you click where the drop button is supposed to be the drop down appears. Any ideas & thanks ... Tag: Memory taken by an object Tag: 92131

How do I evaluate, in c#, the amount of memory taken up by any given object
?

Hi JezB,

Binary Serialize the object to disk.

Hope that helps,

int size = System.Runtime.InterpoServices.Marshal.SizeOf(object);

Hi Jan,

Just a note that this way you'll get an estimate and not an exact amount
(due to memory alignment and other context not serialized).
Perhaps the best way is to check it with a memory profiler..

Neither binary serialization nor marshalling will actually tell you
that information, and there's no way to determine it accurately, in a
guaranteed way.

However, each object has an 8 byte "overhead" plus the space taken for
its member fieds. Each reference is 4 bytes (on a 32 bit CLI), each
Int32 takes 4 bytes, etc. Where it becomes tricky is if you have
byte/short members - depending on attributes, these members may be
"packed" or not.

Don't forget though that two objects could both refer to the same third
object - you'd have to make sure you don't count that third object
twice if you're trying to sum the object sizes...
