    - DataGrid simple question It is probably a very simple question, but I can't find a right DataGrid property that prevents the user from adding new rows. Of course the 'ReadOnly' property does it, but the grid cannot be read only, since the user should be allowed to edit existing rows. However, when I leave ReadOnly set to false, that an empty row is appearing on the bottom of the grid so that the user can add new rows, which is what I don't want.

    - Pause code until file fully downloaded I have a situation where I need to scan a folder for downloaded files and then process those files. I have a file system watcher which is looking for the creation of a file but clearly I want wait until the file is completely downloaded before I start trying to use it. At present I'm trying this... Dim fi As New FileInfo(fle) 'Don't try to read while still being written Do While fi.Length <> sz s = TimeOfDay.Second Do While TimeOfDay.Second = s Loop sz = fi.Length Loop ...but that's going wrong on the sz=fi.length line (not immediately, but intermittently)... telling me that the file doesn't exist. Does anyone have a better way of approaching this? (...and no, the sensible answer of getting the data provider to add the creation of a 0k control file at the end of the download isn't an option.)

    - Background process as delegate I have a winform that will start directly from the scheduler. The program will perform a batch process and put status messages on a winform. I start up the back ground process as a delegate directly in my winform constructor after InitializeComponent();. Is this a good idea or is there a better way?

    - Datagrid row-specific tooltips Anyone know how to get a tooltip on each row of a datagrid ? The tooltip text must be configured depending on the row that the mouse is hovering over, and the hover timer must be reset when the user is moving the mouse over the rows of the grid (but not necessarily moving off the grid). No matter what I try I cannot get this to work ! Not using the grid's tooltip property anyway, but perhaps there is a better way. Tag: Tray application still displays window (sort of) Tag: 86156

    - Databinding and Validation with UserControls Hi folks, I've got a Form with several Controls. One of it is a UserControl. Then I have put some DataBinding to the Controls with control.DataBindings.Add(...); Know there is some strange Behaviour: Fist: When I change to the UserControl (by clicking in the control), it doesn't cause validation on the other control. Only if I change to another Control the validation is occurs. The UserControl has a Property CausesValidation wich in the Designer is set to true. Second: I've got some problem to put the Changed value back to the DataSource. How can I get sure that the changed value of the DataBound Property is put back to the Control?

    - Custom Control Sizes in constructor *and* parent form If I create a custom control that's 200x200, then drag it into my main form, the designer adds code to set the size. This means if I open the control, and change its dimensions, I have to also remove the ".Size = x" line in InitializeComponent of the parent form! Is there any way to stop properties like size, font etc. being duplicated in the form, when they're all already present in the controls constructor?

What I need is to change the default application icon (the one that is seen in windows explorer) to my icon. I tried: - Look for 'application icon' in project settings - no luck, suppose this option is available only in C# or VB projects. - Changing app.ico to my icon: this works fine, but this changes only 32x32 icon, but in list view in explorer this changes to default 16x16 icon - Using /win32icon:myicon.ico as an option of compiler (set in project settings) - it does not recognize this option as known option.

    - At what point does the MDI parent become visible? I want to put code that executes only once at the first available point after the MDI parent form is visible so I can give feedback to the user while the application is retrieving configuration data from a database and doing other setup work. The _Load is too early because the form is not yet visible, and _Activated seems not well suited because it fires too frequently. The closest I've come is to use _Activated with a Boolean set after the first call so the setup code doesn't execute, but it still seems ill-suited. Any suggestions would be greatly appreciated. I'm a DBA by trade, so bear with me. Tag: Tray application still displays window (sort of) Tag: 86128

    - Creating a 1bpp mask from a byte array Hi First of, I am posting to this newsgroup as it seemed best suited even though I am writing C++ for a standard Windows application. The application uses GDI+ which forms the basis of the System.Drawing namespace...anyway here goes: I am trying to create a 1 bit per pixel mask to use as an overlay. The data for the mask i generated dynamically based on user input and is available as a byte array. I get the first failure when trying to create the mask bitmap, the code is a follows: /** * Utiliy method, creates a mask bitmap and modifes the palette accordingly. * @param size Size of the mask. * @param color Color of the mask. * @param pixels The pixels. */ Bitmap* createMask( const Size& size, const Color& color, Byte* pixels ) { Bitmap* mask = new Bitmap( size.width, size.height, ((size.width+3)>>2)*4/8, PixelFormat1bppIndexed, pixels ); UInt paletteSize = mask->GetPaletteSize(); if( paletteSize > 0 ) { ColorPalette* palette = (ColorPalette*)malloc( paletteSize ); mask->GetPalette( palette, paletteSize ); if( palette->Count == 2 ) { palette->Entries[0] = Gdiplus::Color::Black; palette->Entries[1] = Gdiplus::Color::MakeARGB( color.GetA(), color.GetR(), color.GetG(), color.GetB() ); } mask->SetPalette( palette ); free( palette ); } return mask; } Since that didn't work, I tried letting GDI+ create a mask bitmap of the specified size and the copy the pixels into that bitmap. But when I try to display the image I either get nothing or a GPF. My display code is very simple: // Bitmap *maskBitmap; // Defined elsewhere Graphics g( hDC ); g.DrawImage( maskBitmap, 0, 0 ); So it basically just creates Graphics object and attempts to draw the image. The latter fails however... Teis Johansen Tag: Tray application still displays window (sort of) Tag: 86118

I mean if you run your windows with 780x1024 resolution you won't be able to set your height or width to any thing larger than this.. this is really stupid from the IDE to prevent developers from resizing the form larger than the screen area since this would enable you to get a lot of space in design time and/or using scroll bars to put lot of controls in one window..

    - CheckedListBox::SetItemChecked will not display properly on TabCon Hi all I have this checkedlistbox that appears on a winform that has a tabstrip control. The tabstrip control has say more thatn 2 tabs. On the first tab there is a checkedlistbox. The checkedlistbox first loads all possible items from a database; say 10 options total for a user to select. I then make another call to a database table that has the previously selected options for the checkedlistbox. All the data comes back from the database fine. I am able to use the SetItemChecked method to set which ever items in teh checkedlistbox as checked, but when it finally is rendered on the screen, none of the checked items show as checked. If I move the checkedlistbox to another tab that is not to display at the time of rendering for the form, I can select that tab and the items are checked. I am wondering if any of you have seen anything similar to this. Thanks for any assitance. Tag: Tray application still displays window (sort of) Tag: 86113

The issue is that all the controls I place in the inherited child form at design time use say Arial 12 font and the textboxes are 20pixels hi, however at runtime everything ends up twice as large than designed, like Arial 16 and textboxes 40pixels hi. So far this is cool because I infact need to adjust the size of the controls all over the aplication according to the resolution it is being running on. However I don't know what feature is that and need to know what it is in order to control it! Any ideas? is it the base form used by the child windows or is something on the MDI container that somehow "inherits" some property to the controls the contain?

    - Skip LinkLabel in TAB order I have designed a custom control derived from UserControl which contains a LinkLabel and a TextBox. If the user uses the TAB key to move the focus to my custom control I want the TextBox to get the focus and not the LinkLabel. Therefore I set the TabStop property of the LinkLabel control to False (in the constructor of my custom control, after InitializeComponent()). However, the TabStop property of the LinkLabel is ignored and it still gets the focus. As a workaround I tried to override OnEnter of my custom control: Protected Overrides Sub OnEnter(ByVal e As System.EventArgs) myTextBox.Focus() End Sub Unfortunately this doesn't work either. The TextBox gets the focus but immediately afterwards the focus moves to the LinkLabel. Overriding OnGotfocus results in the same behaviour. How could I prevent the LinkLabel to get the focus if the user uses the TAB key to move the focus to my custom control?

    - How to achieve the following functionality with Windows Forms ? I have a useful framework, written in a different language (PowerBuilder), which I'd like to replicate in .Net and Forms, but I'm unsure of how to approach it, as the Event model is being used different between the development environments. Currently we have data entry screens, whose columns have been "wired" into a class that performs checks on the entered data. As the user "leaves" a column, the specific check / business rule is carried out. A lot of the checks are common across all the screens and linking the column to the specific method to be called is as easy a giving the column the appropriate Name. How can I create my own framework which would allow an easy method of connecting / wiring the columns and the method checks together. I was planning on using DataGrids, but can change that if I need to. Tag: Tray application still displays window (sort of) Tag: 86075

After the project has been built the first Button object's location moves up by one pixel! With some experimentation I've found this happens with other objects too but equally, in some circumstanmces, if doesn't happen at all. Can you explain why and whether there is a solution?

    - Urgent Help : Re-select Combobox Value Dear all, I'm doing a winform project which uses "ComboBox" in one of the form. The winform contains "ComboBox" with the values as below: - this.ComboBox1.Items.AddRange(new object[] {"Apple", "Orange", "StrawBerry"}); Users will select on of the item from the combobox and stored into database. Users have the rights to update this record. The question is, how do I select the combobox value base on the value from database? I have used "SelectedText", "SelectedValue", but it doesn't seem to be working. Please Help. Thanks in advance. Cheers, Mae Tag: Tray application still displays window (sort of) Tag: 86068

    - Windows Forms .NET 2.0 Advice Hello, I could use some advice. I have an application to build for a client the must be developed as a windows form application. This is an application that was written years ago using VB6 and an access database. I am an experienced .Net developer, version 1.1 but have built web applications, not windows forms. Should I consider .NET 2.0 for this application? I do not have windows form experience in .net so there will be a learning curve either way. Are there enough new features in .net 2.0 windows forms to consider this? Also, can you point me to any good docs on the subject. Thanks scott Tag: Tray application still displays window (sort of) Tag: 86060

    - Windows Form and Windows Form User Control - Where Is The Method That Would corresspond To A Web Form Pre_Render Method Hello MyMainWebPage.aspx contains MyUserControl.ascx MyUserControl.ascx has a DataTable Property MyDataTable MyUserControl.ascx has a DataGrid which whose datasource is MyDataTable (or technically it's private accessor but that I don't think is an issue here) MyMainWebPage creates a DataTable dt . I then do a "MyUserControl.MyDataTable = dt" In order for the data to appear in the user control grid I must do the "MyUserControl.MyDataTable = dt" in the Pre_Render of MyWebPage I want to do this type of thing with a window form and windows user control. Where in the windows form user control would I bind the datatable? If I do it in the user controls page_load it does show the data in the datagrid?

    - Problem binding a listbox to an array Hello people, I am having problems binding a listbox to an array. Using Visual Studio 2003 with framework 1.1 That's the array: internal class Data { private Data() {} // static class public static readonly string[] states =3D { "Alabama", = "Alaska", "Arizona", /* ...*/ "Wisconsin", "Wyoming"}; } I also have a listbox on a form. The auto-generated code is: // listStates this.listStates.Name =3D "listStates"; this.listStates.TabIndex =3D 0; this.listStates.Location =3D new System.Drawing.Point(8, 16); this.listStates.Size =3D new System.Drawing.Size(100, 82); this.listStates.SelectionMode =3D = System.Windows.Forms.SelectionMode.MultiSimple; Question number 1: In the designer, the DataSource property of the listStates ListBox is = not editable. I would like to bind it to the array at design time but I cannot. I that supposed to be like that or am I missing something? Question number 2: When I added the following statement listStates.DataSource =3D Data.states; it appeared to work but I started having weird behaviour regarding the = selection. In particular, after selecting several items and unselecting all of = them, the first item would become selected. What am I doing wrong?

    - Change mouse cursor when points to specific cell I am creating a linklabel look-a-link in a datagrid with the following code by overriding the paint sub: If column = 0 Or column = 3 Or column = 4 Then Dim UnderlineFont As New Font(Me.DataGridTableStyle.DataGrid.Font, FontStyle.Underline) Dim rect As Rectangle = bounds Dim value As Object = GetColumnValueAtRow(source, rowNum) g.FillRectangle(backBrush, rect) g.DrawString(value.ToString, UnderlineFont, Brushes.Blue, RectangleF.FromLTRB(rect.X, rect.Y, rect.Right, rect.Bottom)) Else MyBase.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight) End If I only create the linklabel look-alike in specific rows and columns. Now I have to have the cursor change to a 'hand' when the mouse moves over a cell. Note! I am creating the datagrid programmatically so I do not know what rows will contain a link (so I can not use the example by George Shepard in sycfusion). Also, there is NOT a mouseup or mousedown event to work with. I only want the cursor to change to a hand on a specific cell, not a whole row. I have been trying to do with with the datagrid.hittestinfo but can't seem the to get it. Thanks! -- Suz Tag: Tray application still displays window (sort of) Tag: 86041

Buddy,

You should probably post some sample code.
