    - Windows message queue question Hi all! I'm writing a windows application, that contains a control that shows a bitmap. The bitmap is painted in the controls OnPaint method, using the Graphics.DrawImage method. It is possible to drag the bitmap around inside the control, using the mouse. While dragging the image, I call the controls' Invalidate method every time i get a MouseMove-event. So far so good. The problem is, that, when the image is large and I drag it around and then stop moving the mouse, the image often still keeps moving over the control for a few more seconds. I guess, this is caused by MouseMove events, still contained in the applications message queue. A profiling utility showed, that OnPaint was called exactly as often as MouseMove. I was surprised about that, since I thought that OnPaint would be called asynchronously and only when there is time for. Can anybody explain this to me? How can it happen, that there are MouseMove events in the queue for such a long time and why is OnPaint obviously called every single time, Invalidate is called? (I don't call Update!) Is there a possibility, to drop all MouseMove and Paint events, currently contained in the message queue, except the last ones? Does anyone know another solution for the problem? If this is the wrong NG for my question, wher else should I post it? Thanks for any comments Markus Tag: change the backcolor of a column in a datagrid Tag: 59719

    - detecting a change in the datagrid Hello, could you tell me how to detect a change in the datagrid (i.e. when you actually change the data and click the pen symbol in the grid and not when you just tab to the next field). Therefore datagrid_currentcellchanged does not work. Thanx in advance Robert Tag: change the backcolor of a column in a datagrid Tag: 59717

    - User authentication in Web Service calls from a remote NTD app I am developing a Windows Forms application that makes requests to a web service and in return receives configuration data that is user specific, i.e. based on the user's window's authenication on the server side domain. My problem is that I am unaware as to how I should configure the app so that when it calls into the web service, the web server will be able to identify the user. Initially the application will be running on the same domain either over a LAN or though a VPN connection although it is anticipated that in the future connections may be made from a m/c outside this remit although the latter scenario does not have a high priority right now. Any illumination on this topic will be gratefully received. Thank you. Tag: change the backcolor of a column in a datagrid Tag: 59714

    - Cannot remove windows form from .net project I had a windows form named "FormOrdersList" that I deleted from the .net project. During the deletion i was asked wether I wanted to update something on the very same form (I dont remember what it was) and I just clicked "yes" which I believed to be the default. Then I tried to add an inherited form with the name "FormOrdersList". I get the response that FormsOrderList cannot be added because it exists in the project from before. I then try to add a normal (not inherited) windows form named "FormOrdersList". This works fine as well as deletion. But when I try to add "FormOrdersList" as inherited form again I get the respons that the form exists in the project and cannot be added. What can I do to remove all garbage in the .net project for the old form?? Regards Tore Tag: change the backcolor of a column in a datagrid Tag: 59709

    - Passing parameter to Smart Client application Hi I am creating a smart client application. The requirement is as such....An asp page gets loaded.(NOTE: an asp page gets loaded not aspx page). This page is actually a search page in which the user enters some input in a textbox. On the basis of the value entered, some results are displayed in form of links.On clicking the link, i want to call a smart client application by passing in some parameter that is returned along with the serach results. What i am doing is on clicking the resulted link, i am calling an aspx page.(NOTE: i am loading an aspx page. not asp page). Which in turn calls the smart client application. But the issue is that i am not able to pass the parameter to the exe. I need to do this because my smart client application does something on the basis of this parameter. Does anyone has any idea on how to pass parameter to the exe from the aspx page and how to use the parameter inside the exe. Thanks Suvendu Tag: change the backcolor of a column in a datagrid Tag: 59705

    - BeginUpdate/EndUpdate causing mouse move I have implemented a custom control with BeginUpdate/EndUpdate functionality. The implementation of BeginUpdate basically sends the WM_SETREDRAW message by P/Invoking SendMessage and setting wparam to 0 and EndUpdate sends the same message with wparam = -1. When I invoke these methods on my custom control, I am also getting the MouseMove event. Has anyone else seen this? Is there a way to prevent the MouseMove event on the control when BeginUpdate/EndUpdate is called? Thanks, Abhishek Tag: change the backcolor of a column in a datagrid Tag: 59692

    - ListView row height and custom text I am working with the ListView control and I only seem to be able to place regular text in each cell. I would like to place say a paragraph of text (that does not require the user to lengthen the column width), basically a word- wrap function inside a cell. I cannot seem to be able to place say a label control into a ListViewItem. Does anyone know if you can place controls other than text strings into a listview item or if there's an easy way to make column widths word-wrap instead of requiring resizing? Thanks so much!

    - Databinding to custom class I have a custom class with its properties bound to controls on a Form. If I change the values of the controls, the changes are carried back to the object. Is there any way to reverse this - so that programmatic changes made to the object are reflected back to the form? I'm not making a list-type object, so I don't want to have to use IBindingList.

    - Strange ComboBox Behavior I am experiencing strange behavior working with multiple ComboBoxes on a form. I have several ComboBoxes that I configure in code the way I have in the past (only a single ComboxBox on the form).

    - Getting the actual size of my form Hi ! I want my app to fit the desktops boundries (like the taskbar) you get the available size, calling Screen.PrimaryDevice.workingArea. That works fine. But when i set the height of my form to that of the workingArea it is the menu height to large. So somehow the menu doesn't cares about the height of the form. First question, how do i get the height of the menu to substract it from the actual height of the form. The second thing is, to determine the actual drawingRectangle of my form, that mean first without the menu, okay. But the second thind is that calling this.ClientRectangle seems not to substract the Window Caption Bar with the maximizebox and close button. Second question, how do i get the height of the Forms Caption Bar. Thanks for the help, nick Tag: change the backcolor of a column in a datagrid Tag: 59651

I need a function (function getMsg (msgCode as string) as string) so I can use it like messagebox.show(getMsg("xpto")).

    - Anchor problem on dynamic form I have a form inside my application (mdi child) to which I add a varying number of custom display objects at runtime. To do this, I suspend layout, add the items, and then resume layout. I am having a problem with the header image of the page. Since the form is resizable, I am trying to anchor a picturebox to the top of the form. When I do this, the image is drawn off center by 100 pixels to the left or so (and moves with a resize). If I anchor it top and left, it works fine but is not centered in the screen (and does not move with a resize, as one would expect). Has anyone seen this type of behavior?

    - .NET Framework 1.0 Validating event bug? Hi, I'm putting together an app where I need to be able to stop the user from switching focus from a control (e.g. a DataGridTextBox) if the value in the box is bad. I have a test app where I dump out a log message on all the standard events (enter/leave/validating/validated, etc.). When I'm in a DG cell and enter a bad value (checked during Validating and set e.Cancel = true), I've found that events past Validating continue. In this case, the DG's MouseDown handler is called, then a whole bunch more entering and leaving (including of the original textbox and ultimately the bad value is sent through ColumnChanging on the DataTable under the grid. Any idea why Validating doesn't seem to stop the event progression? Setting Cancel = true stops the Validated event from showing up, but does nothing about the MouseDown and later stuff. Are there known bugs in .NET 1.0 about this? I was unable to find anything in searching the MSDN Knowledge Base and various Google references.

    - disabled toolbar button images An exhaustive search of all dotnet groups seems to indicate that no one has been able to solve the problem of disabled toolbar button images providing a grey box or some other lame appearance. Has anyone been able to solve this? From the postings it sounds like it may have something to do with the imagelist transparency color, the imagelist color depth, and possibly the original image file color depth. Anyone? Scott.

    - Control Names in the designer I have a control with a property of type collection with a special editor that lets me select controls from the available controls on the form. When clicking the "..." on that property, I build a list of all the controls in order to show what's available. I'm using the .Name property of each control on the form. The problem is with "my" controls as opposed to the dotNet controls. If I have a TextBox on the form and I change it's name in the property window, then the next time I view the list of controls I see the new name. But when I do the same with "my" control (which inherits either from Control or from UserControl) the name isn't changed. Has anyone seen this behaviour ?

    - Visual Studio selection frame hiya- i am trying to implement a selection frame like visual studio has in the form designer when you select a control on a form. the frame has little handles for resizing and allows the user to know what controls are selected. i wrote a control that does this and it works well except for one thing. the frame needs to be one layer below the selected control. i have found no methods to set the z order other than bringtofront/sendtoback. anyone have any thoughts on how ms implmented there selection frame or a better way to do mine. basically i want it to be as close as possible to what is in visual stuido. thanks - fragget Tag: change the backcolor of a column in a datagrid Tag: 59578

    - Form AfterLoad I need to execute some code after the form loads. OnLoad event doesn't work, because it fires before form is displayed. I need the form to display, and then do something. Is there any event that I can use? Thanks. Tag: change the backcolor of a column in a datagrid Tag: 59572

    - tough inheritence question -Form A inherits from form B. -I am iterating over the controls on an instance of form A. -Is there any way for me to tell if a given control came from form A or form B?

    - How many labels can a form suport hi there, i'm developing an aplication that uses 4 forms. Each form has about 2000 labels, when I try to open my third form, an error ocurrs, but no error mesage appears. I've realised that if I try to crate a form collection like: sub Test() Dim f as new Form1 f.show end sub and if form1 has 300 labels and no other controls, the program hangs, when the 33rd form appears (about 9900 labels). What can I do to work this Out ? Thanks Tag: change the backcolor of a column in a datagrid Tag: 59563

    - Picturebox and icons bug? Hi, I've come across a strange problem when using the Picturebox to display an 32x32 pixel Icon file. When first setting the "SizeMode" property to "StretchImage", it seems to work properly (i.e. the Icon is displayed with the full 32x32 resolution). However after closing and opening the form designer, the image seems to revert back to 16x16 resolution which looks horrible when stretched to the 32x32 pixel size of the picturebox. Here's the steps I used to recreate this problem. 1) Add a picturebox to a form 2) Make it's size 32x32 3) Assign an .ico file to the picturebox's Image Property. 4) Set the "SizeMode" property to "StretchImage". Notice how the icon uses the full 32x32 resolution. 4) Save and close the form designer. 5) Reopen the form designer - the icon now looks crap with its 16x16 resolution stretched to 32x32 I'm using VB.net in Visual Studio 2003 and .net framework 1.1 Any help anybody can give would be much appreciated.

Hello I have a datagrid textboxcolumn setup as follows:

Dim tcJobkey As New DataGridTextBoxColumn
tcJobkey.MappingName = "Jobkey"
tcJobkey.Width = 50
tcJobkey.HeaderText = "Job key"
tcJobkey.ReadOnly = True

Please could you tell me how to set the back colour of
this particular column, if this is possible.
