    - Visual Inheritance for ComboBox Hi All, Just been toying around with inheriting from the ComboBox control. See below a simple example of the new ComboBox class. // start MyComboBox.cs file using System; using System.Windows; using System.Windows.Forms; using System.Drawing; namespace MyComboBox.UI { /// <summary> /// Summary description for MyComboBox. /// </summary> public class MyComboBox : ComboBox { public MyComboBox() { this.ForeColor = Color.DarkBlue; } protected override void OnHandleCreated(EventArgs e) { if (this.DesignMode) { this.Items.Add("Design Mode"); } else { this.Items.Add("Run-time Mode"); } this.Items.Add("Orange"); this.Items.Add("Apple"); this.Items.Add("Pie"); } } } // end There's no problem adding the control to my toolbox. Also - no problem dragging and dropping the custom combo onto the design canvas. Strange thing is, after switching between design time and code a couple of times and running it - the font seems to change into a bigger font, something like Arial bold or such. Also, I suppose I need to specify some attribute tags before the class definition. Any ideas or suggestions? Thanks a bunch, Wim Hollebrandse Tag: form with datagrid steals focus Tag: 52023

    - Menu shortcut keys do not work when Form.Show is called. I have a form that I build in C# that does not seem to annunciate a menu item selection when a shortcut key is pressed. It only seems to occur if I display the form using the Form.Show() method. The problem does not seem to occur when I use Form.ShowDialog(). Can someone explain how I can get around this problem? -- ----------------------------------- Ken Varn Senior Software Engineer Diebold Inc. varnk@diebold.com ----------------------------------- Tag: form with datagrid steals focus Tag: 52012

    - MDIChild forms maximizebox. Hello ALL, I have this situation: 1. A MDI Form named frmPrincipal; 2. A MDIChild form named frmCustomers; When I show the frmCustomers form, from a click event of a button of frmPrincipal, like this: frmCustomers.MdiParent = this; frmCustomers.WindowState = FormWindowState.Maximized; frmCustomers.Show() The frmCustomers form shows ok, but the minimizebox, maximizebox and controlbox appears, and I can´t like this. In the frmCustomers properties I set false to maximizebox, controlbox and minimizebox, but they appears yet. I try to remove the border of the form (set FormBorderStyle = None) but don´t work too. Please, how can I hide this buttons? Thanks in advance and sorry my English. Fernando Lopes Marília - São Paulo - Brazil. Tag: form with datagrid steals focus Tag: 52009

    - Problem with drawing over the top of a background form Hi, I am hoping someone can point me in the right direction. I am working on a program that has a form that has a background mage that the user can change. Currently I assign in directly to background image. After an image is assigned to the background the user has the ability to draw rectangles on the image using the mouse to define the regions. To do that I create a bitmap and constantly redraw the rectangles on it that are stored in a linked list each time the form repaints.. the problem is that because of this bitmap, I never see the image assigned to the background. Of course this makes sense since I am creating a bitmap. I've tried setting the bitmap to be transparent, and that allows me see the background image, but everytime I use the mouse to draw or resize a region, it doesn't refresh properly and I'm left with tons of rectangles on the screen, instead of just the final rectangles position. Is there any easier way to do this? I've also tried to assigned the .BMP image I use directly as the bitmap I am creating the rectangles on rather then the background, but then I get another error saying "Additional information: A Graphics object cannot be created from an image that has an indexed pixel format." The bmp is an 8 Bit format image. I've also tried converting it to a GIf with no success. I was going to post some of the code, but figured the post was long enough, if anyone is interetsed in seeing what i have so far, just let me know. I appreciate any help you guys can give me.

    - Am I doing something wrong? (Variables) Hiya all, I am developing a windows form application. I am coding in C#. What I have is two forms/Classes, frmMain & frmAdd and they both have the same default namespace "Q.A._Testing_Centre". In frmMain I have initialize & instantiated my variable as "public string userName", where the user input name is stored. I am trying to get the stored data propertied from my frmMain to my frmAdd. I thought this is the correct syntex for outputting the info in my textbox (scratching my head), maybe it's not. So please let me know if you can help, or where I'm going wrong. Code is as follows: namespace Q.A._Testing_Centre { public class frmMain : System.Windows.Forms.Form { public string userName; <<<---- I want the data from here ... ... ... namespace Q.A._Testing_Centre { public class frmAdd : System.Windows.Forms.Form { private void SubMainMenu() { frmMain Main = new frmMain(); txtBoxSample.Text = Convert.ToString(Main.userName);<<<--- to output in my textbox here ... ... ... I have tried a sample textbox with in frmMain and this data is in fact stored until I exit my program. But I cannot seem to reproduce the same textbox output in frmAdd. I seem to get a blank textbox area. Alternatively I have try "txtBoxSample.Text = Main.userName" syntex which does not work as well. Or maybe if someone has a better alternative, please feel free to let me know. All help is truly appreciated & thank you all in advance. MikeY Tag: form with datagrid steals focus Tag: 51989

    - Is print preview in .NET wothwhile? Hi! I am preparing to write a small library for generating reports. One of the key features is that it must support print previews. .NET has a PreviewPrintControler but according to the docs it is keeping the whole preview in Images. The library should be able to preview quite large reports (over 100 pages) also on resource starving computers (like 64 MB RAM 300 Mhz Celerons). Would PrintPreview eat the whole memory available or does it have some optimizations to counter the problem? What are your experiences? Regards!

    - Win98: DragDrop registration fails everytime I'm ripping a thread that I created a few days ago, since I used the exact same subject line as a previous one. In addition, I can also say that since I posted this thread, I've come to the conclusion that this application is hitting some sort of wall with regards to Window handles. I'm leaning towards this being one of the primary issues because when a user selects a "tool" from a Form (it launches the core application, which is quite large), you can immediately kill the Form, go back to the tool selection Form...select it again, and it will _always_ fail to load the 2nd time. The application just dies. Furthermore, I've got try/catch blocks all over the place, sending the Exceptions to a logfile, and nothing ever gets logged once it gets in this state. You're forced to do the ole' Win98 CTRL-ALT-DEL at that point. So, the question is this: If I'm correct (or partially) in that Window handles might be the culprit, how do I resolve it? I spent an entire day forcing dispose() on everything I could possibly think of, as well as using things like the Performance Counters to identify problematic (meaning, resource hungry) classes, and I still get the same result... Can anybody (Microsoft?) help or even give me some kind of direction? Here's the original post... ----------------------------------------------------------- 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. Can anybody shed any light on this? Any workarounds? Tag: form with datagrid steals focus Tag: 51926

    - 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).

    - 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: form with datagrid steals focus Tag: 51842

    - Inherited Control Location I have an inherited form that has 2 broup boxes and 2 controls (textboxes) on each group box. I am unable to move controls out of the group box. Is this an inherited controls issue, or am I missing something else? Tag: form with datagrid steals focus Tag: 51839

    - 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: form with datagrid steals focus 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?

Hi. I'm having a very annoying focus problem. I have a class
(MyDataList) which implements CollectionBase and IBindingList. This
class is bound to a data grid.

whenever my MyDataList is updated [example: OnListChanged(new
ListChangedEventArgs(ListChangedType.Reset,-1));] (another thread
invokes updates on the UI thread) the form containing the DataGrid
takes focus and then acts like something set TopMost = true on the
containing form!

I can't figure out what is causing this, and it's driving me insane!!
Has anyone encountered this before, and found a fix? Or does anyone
have a suggestion? (extend DataGrid and override some protected
event?)
