    - ListBox Performance - SetSelected Hi there, I have the case where I am trying to optimize some slow code that selects listBox items. For approximately 6,500 items, the IndexOf method takes about 3 seconds on a 2.4GHz machine, and SetSelected takes about 9 seconds. The label lookup from the lable map takes about 0.004 seconds. Is there any way of selecting items in a quicker, possible batch fashion? SelectedIndices appears to be read only. Surely it can't take 9 seconds to select all these indexes when only 10 or 12 are displayed at any one time. I've tried SuspendLayout() and ResumeLayout() to try to avoid code that updates the display after every selection, but the performance remained the same. for(int i = 1; i <= aenumElements.Count; i++) { string alabel = m_idLabelMap[aenumElements[i]] as string; int aindex = listBoxElements.Items.IndexOf(alabel); if(aindex >= 0) listBoxElements.SetSelected(aindex, true); } Any tips would be greatly appreciated (short of re-working the use case to not require 6,500 elements of course). Thanks, Wayne. Tag: Program the function key of Datagrid Tag: 51863

    - Client/Server Samples with Business Logic Layer Sorry for the cross-post, but I didn't know whom to ask.. Are there any samples for a true C/S app (preferably VB, but C# is welcomed) with a middle tier using datasets/datatables similar to the the Fitch/Maher sample w/VB6? The only thing i can find on windowsforms.com & MSDN is TaskVision, which is overly complicated for my needs(dont need to expose data via web services). I have adopted the "MS Building Blocks" data access class, but it's only been used in ASP.Net samples, and would like to continue using it in the BLL. Is this possible?

    - Disable MDI Scrollbars Hi all! Relating to an earier post I made. I tried the EnableScrollBar API which didn't seem to work for me. This is how I'm declaring it: [ DllImport("user32.Dll", EntryPoint "EnableScrollBar") ] public static extern bool EnableScrollBar(System.IntPtr hWnd, int wSBflags, int wArrows); Then using it like so: EnableScrollBar(this.Handle, 3, 3); If anyone has any success in disabling MDI parent scrollbars then I'd love to know how you've done it!

    - Is it true that Windows Forms don't use config files? WROX's "Professional ADO.NET" makes the following statement on page 54 when discussing obtaining connection strings from a config file: "In Web applications this file must be name web.config. In Console applications, the configuration file also ends in .config, but is prefixed with application name, such as MyApp.exe.config. Windows Forms applications do not use configuration files." I am curious why Windows Forms do not use config files and also what about Windows Service apps (or they treated as "console" apps?)? Tag: Program the function key of Datagrid Tag: 51842

    - Datagrid: Full Row Select and Other Options like in TaskVision All, Maybe I'm just missing it but how do you do the following three things with a WinForms DataGrid... 1: Make it so when the user clicks on any part of a row the FULL row becomes selected 2: Hide the add new row from the bottom of the grid 3: Remove the grey side bar from the left of the grid For an example see the main grid in the TaskVision Demo at: http://www.windowsforms.net/default.aspx?tabIndex=7&tabId=44 This is the EXACT grid I want. I took a look at the source and I can't seem to find where they made the tweaks. The dgGrid is of type System.Windows.Forms.DataGrid so it is still the basic grid. I'm pretty sure it is something from the class "public sealed class MainFormDgStyle" but I can't seem to find what. -Jason Tag: Program the function key of Datagrid Tag: 51836

    - databinding lose focus Hi, I was wondering if someone could give me a workaround for this... I have a windows form with a number of text boxes that are databound to a datatable. My problem lies in the fact that (to the best of my knowledge) you must tab off of the control (ensure it has lost focus) before it will update the datarow with the information that was typed in the textbox. This is an issue because I give users the option to 'save & close' the form from a menu item, and menu's are specifically designed not to accept focus - thus focus never leaves the control the user was last typing in, therefore the last controls contents never make it back to the datasource. I've tried removing focus from the control programatically as part of the 'save & close' function, but this doesn't seem to work. Any ideas?

    - Image Resource Hi, I have a picture box control in my form and I have 2 .GIF (animated GIF image). And I want to display those GIF image in my picture-box (at first, I want the control to show the first image and a few seconds later, I want the control to present the second image). The following are some ways I have try to deal with this task: - Insert two picture-box control into my form and each control shows only one image; and then, I will toggle the Visible property of them. This is not a good solution if I want to display 10 or 100 images - I make use of ImageList to keep my images. Through it's a very good idea, my animated GIF image stop animating. It's become static image. - Using the Image.FromFile to load image. But I don't want to reveal the images to the user so that they can open,edit them and change my application. Is there better solution ? I have used Visual C++. Using images in C++ is very easy: just insert them into the resource file and display them with. Is there any easy way to use resource in C# ?

    - Control Licensing Help please! I'm trying to implement control licensing using the LicFileLicenseProvider implementation of the LicenseProvider class, but I cannot seem to get the right format either in my <controlname>.LIC file, or in the first line "myClass name is a licensed component" in the file. (I will implement my own validation once I get the basic structure working.) All I can find in the literature is a reference to using the fully qualified name of the control, and the fully qualified name of the component. My control is called ctlAlarmClock and it's contained in a component class called ctlClockLib. So I would have thought that filename = ctlClockLib.ctlAlarmClock.LIC text = "ctlClockLib is a licensed component" should both work. Any help would be greatly appreciated.

    - DragDrop registration failed I have a C# Application that is posing some interesting issues when run within Win98. Let me preface this by saying that everything works like a charm under Win2000. Anyhow, the current issue is that under "certain" circumstances (there's no logic as to how/why this happens), you will fire up this application under Win98 and get a "DragDrop Error: registration failed" MessageBox from JIT. The source code line in question is, of course, a simple "this.AllowDrop = true;" property. If I were to remove it, the problem would go away. Of course, I need that call in order for the application to function correctly. And before anybody asks the obvious, I _do_ have the following line in my main Form: [STAThread] static void Main(string[] args) I can't really make heads or tails out of this issue, and it definitely presents itself only under Win98. This particular Win98 machine is up to scratch, in terms of patches/updates/etc. The OS has IE6.0 installed, as well as .NET runtime v1.1. The Application is compiled using .NET Studio 2003.

    - TextBox Maximum Line Limit? I have a multiline TextBox control and it won't let me paste in more than 964 lines(30,841 characters) of text. Have I hit some kind of limit in the TextBox's capabilities? Thanks, Steve Tag: Program the function key of Datagrid Tag: 51688

    - Slow refresh on some WF controls Certain controls refresh very slowly (Label, ListView, PictureBox etc...), slow enough on older machines that people think something is wrong with the application.
