    - Event on record change I have some controls on my form which are bound to a dataset and some which are not bound. But whatever record is displayed on the form, I want to populate those control (datetime, combo, etc.) with the data in the current record. What event can I do this in ? PositionChanged of bindingContext - is this called before the record is current or after ? if it is after, I can use this. Please advise. HS Tag: Launch WebBrowser Tag: 84122

    - How to refresh SOME records in the datagrid but NOT SQL Server ? I am sure this is a dumb/simple question, but I am new to this stuff, so request for patience with me... I have OUTSIDE knowledge that there is activity regarding some records in a parent / child set of tables I am showing in what I want to be a read-only view in a grid. I have primary key values, but don't know if it is just a change to existing records, or if the record was recently inserted. I want to reflect these changes to the grid in realtime as they occur, by using the primary key to query certain records and get them updated in the datagrid. I started out binding the grid to a DataTable. But I had trouble detecting column sorts, and the need to show some status information for the current cell. I switched to using a DataView and that fixed that. Then I wanted to show work-order/line-item levels, and so I created a datarelation in a dataset, and bound to that, and this works (pretty good). I thought if I queried JUST the work order and line items I know have changed, this would be very efficient. I just need to integrate those data updates to grid. From docs it appeared that DataTable.LoadDataRow would allow me to import the values from the update query data set, and would then update my grid with additions and row value changes. But I get duplicate primary key errors, which suggests to me this is trying to update the database, rather than just my in-memory dataset and the display grid. This makes me wonder if I in any way change the dataset if it will be attempting to post those to the database underneath, which I do not want. Am I going to have to implement my own list structure to bind to the grid? If not, how is this done with datasets? Tag: Launch WebBrowser Tag: 84115

    - SelectedIndexChanged event with listview I have a form with a listview to allow users to select an item. When they select one I fill in controls below it for them to modify the values. They can also just enter new values in the controls without selecting a listview item in order to insert new records. After entering new data if they select a row in the listview I prompt them to make sure they want to save the changes. If they select 'Cancel' I want to not highlight the newly selected row and leave the data in the detail controls as it was. Otherwise the new row is selected and the listview item is used to populate the detail controls. The problem seems to be that when I clear the selected items for the listview the selectedindexchanged event fires again. I get the yesnocancel prompt twice. If I step through the code in the debugger I only get it once. I tried using a bool to skip the handler when clearing the selection but it seems like the highlighting of the selected row then sometimes happens after the clearing so it ends up in the selected anyway. I tried playing with the clicked event and others and the events don't seem to always happen in a predictable order. Each thing I try seems to create new issues and it seems this shouldn't be this difficult. I've done similar things with the datagrid but would like to use listview. Basically want to be able to prompt the user sometimes when they select a new listview item and if they "cancel" I want to be able to clear the selection or set the selected item to a prior selected item without prompting them a second time. Any help would be appreciated. Thanks in advance. Jeff Tag: Launch WebBrowser Tag: 84112

    - Control Validating Event Odd Behavior I now know this event is quirky. I am seeing something odd, *though*. When I set a break point inside a validating Event Handler, I see the desired behavior when setting cancel = True. "If the test fails, you set the Cancel property of the Validating event's CancelEventArgs to True. This cancels the Validating event and causes the focus to return to the control. The practical effect is that the user cannot leave the control until the data is valid." However, when not running in debug mode I do not see the desired behavior when cancel = True. I am able to leave the control even though the data is not valid. Make sense to anyone? Greg Robinson Custom Data Systems, Inc. www.cds-am.net Tag: Launch WebBrowser Tag: 84102

    - Calling .NET using COM I have a C# Windows Application that was built using an XML-based framework (It's fairly complex, but simplifies our development considerably.) We have recently integrated this application with a COBOL application, in that the COBOL application will call our .NET forms. I have discovered a few issues with this, and hope someone may be able to help in fixing them. Most of the problems seem to revolve around the Windows MessageLoop, threading and some third-party components (namely, Janus GridEx and Infragistics Toolbars). (I posted to their news forums, but have not had any luck there.) I think the problem may be more in how I am creating and using the thread. I have the code here that is used when a form is called from the COBOL application. One thing I have noticed is that if I call the form using System.Windows.Forms.Application.Run(_child) , the form works perfectly, but the user cannot do anything in the COBOL application - it's "frozen" until I close the .NET form. If I use the following code to call the form, the user can do stuff in the COBOL application, but the Tab, ESC, Alt, etc. keys do not function as expected on the third-party components, which may do something of their own with the keys. For example, the Janus Grid should Tab from column to column, but does not. Instead, it will tab from control to control. I have tried looking at various properties of the thread the form is on, the ApplicationContext, the Application, etc, but nothing seems to be different from one call to the next, except for the thread's ID. Any help would be greatly appreciated!! The code to create the thread is: _applicationcontext = new System.Windows.Forms.ApplicationContext(_child); ThreadStart _threadstart = new ThreadStart(this.StartMessageLoop); Thread _thread = new Thread(_threadstart); _thread.IsBackground = true; _thread.ApartmentState = ApartmentState.STA; _thread.Start(); Where _child is the form with the grid, and StartMessageLoop is: private void StartMessageLoop(){ Application.Run(_applicationcontext); } Tag: Launch WebBrowser Tag: 84100

    - Problem with Opacity and Clipping on a textbox I have a derived textbox which draws an XP border around the control by catching the WM_NCPAINT message. The control works fine until the Opacity of the form is set to something other than 0. Setting the opacity to anything other than 1 causes all sorts of problems. For example, the DC returned by GetWindowDC is not aligned with the actual location of the window so the window is drawn in an incorrect location (it's offest by the width and height of the NC border), the drawing area in the DC is the wrong size so I cannot paint the entire NC area, the client area is not correctly positioned and the mouse hit testing is incorrect. In general things are a mess when opacity is set to anything other than 1.

    - The private components field: where is used? Hi there Every time I create a new Form in the VS 2003 IDE i see the following entry private System.ComponentModel.Container components = null; which constantly remains null, when I add controls (say a Button) or components (say Timer) on the Form. The protected Dispose() checks if (components != null) which always returns false. Questions: 1. Where and when that private "components" field is used? 2. If it is always null a. can I delete it safely? b. why I don't see any compiler warning? Also, that same declaration private System.ComponentModel.Container components = null; is done by the IDE when I create a new Component or CustomControl file. But I don't intend to use it.

    - listview scrollbar range not correct I implemented a double buffered listview to eliminate flicker. I set the following styles, then overrode OnPaint and did the drawing. Everything looks great! However, if I change the font from default, the column headers are not drawn with the new font and worse yet the scrollbar doesn't know that font height has changed and I can never scroll to see the last few items on the list. Short of adding my own scrollbar, is there a way to let the column headers and scrollbar know about the new "range" when the font is changed?

    - Microsoft: Help with OLE documents... Hi all. I have an application to draw and design different documents, that supports linking and embedding of other documents (like, for instance, Corel Draw or Word). Then, the user can print their designs "WYSIWYG", so I load the external document inside an OLE document container control (VB6), get a handle to the object and invoke OleDraw with the hDC that I want the object in. This have been working excellent, and this application is largely distributed among our clients. The problem is we want to migrate to .NET (any language, VB, C#, C++, ...), but there's no OLE container that lets me obtain a handle to an OLE document. I know you could import COM and ActiveX, but this particular control (included in VB6) CANNOT BE IMPORTED NOR INSERTED in .Net. Microsoft calls this a "migration issue" and warns us about it, but how, then, can I draw an Ole document inside our application (let alone open, edit, update, etc)? Is Microsoft planning to update this component for VS.Net 2005? Or is there an alternative? I know I could load an OLE document "the hard way", but those are methods so obscure, I get lost before even starting to insert the document in a container... If this is the only solution, is there an easy (as easy as this can be) example that can lead me to accomplish the insertion of a document inside mine? I know it can be done, because RTF editor lets you do it. It even lets you open and edit the document, and "paste special", but I don't seem to accomplish getting a handle to any of those inserted objects... Thank you for your time, VBen.

    - child mdi forms in different threads Hi, I want to open up a number of child forms in my main mdi container form, but I want the processing that will happen in each child to happen in a different thread. I tried something like this: ChildForm childForm = new ChildForm(); shildForm.MdiParent = this; Thread thread = new Thread(new ThreadStart(childForm.Show)); thread.Start(); It workd fine for the first childForm, but the next one doesn't open up. It just hangs. Is this how things are normally done or is there another way? Thanks in advance. Tag: Launch WebBrowser Tag: 84014

    - ListBox, items get corrupted. Hi there I've implemented a modification of the common ListBox control. It's used for displaying a collection of fonts - eigther system fonts or fonts from a custom folder. But somehow, if I'm displaying custom fonts retrieved using the PrivateFontCollection, and I'm resizing the form or overlapping it with some other window - the items get corrupted. (Items are actually just Font-objects). At first it draws perfectly - but after some time resizing the window it crashes throwing the ArgumentException withing the item's (Font object's) name field. I've got no problem at all displaying system fonts. Resizing as wild as possible doesn't make it crash. Any suggestions? Tag: Launch WebBrowser Tag: 83983

    - PrintDocument and PrivateFontCollection Hi there... I'm writing a tiny utility to display various fonts - system fonts or custom fonts chonsen from some folder. Also I want to give the user the ability to print all the fonts - and that's why I've implemented a print (preview) function. But I've got the following problem: When trying to print and display fonts that aren't installed in the system - it doesn't work. I'm creating a PrivateFontsCollection from all font-files from a custom folder, and then drawing some certain string with each and every font in this collection - but it won't draw using the custom fonts, but automatically switches to "MS Sans Serif" It seems like I'm able to retrieve name, size, etc - but it just wont draw with the correct font face. I've got no problems drawing fonts installed in the system - retrieving them via InstalledFontCollection. That works like a charm. I was having the same problem using a RichTextBox to display the fonts at first - but then I implemented my own ListBox-thingy custom made for my purpose, and that worked fine as well. Can it be that RichTextBox's and the PrintDocument have problems drawing using custom non-system fonts? What can be the problem? Tag: Launch WebBrowser Tag: 83982

How can I launch a webbrowser from my windows forms applications? The
reason I need that is because I have a DataGridView with links in one
of the columns. When clicking on it I process the click and then want
to start a webbrowser loading the site that the link was pointing to.

Thanks,
Rob

Use the Process class as this little C# hack does :

using System;
using System.Diagnostics;

class Class1
{
static void Main(string[] args)
{
Process proc;

proc = new Process();

proc.StartInfo.FileName = "http://msdn.microsoft.com";
proc.StartInfo.Verb = "open";
proc.StartInfo.UseShellExecute = true;
proc.Start();
}
}

Will
