    - Debugging several serviced components in a windowsforms project >> using vs.net 2003, .net framework 1.1, C# >> when a solution has a windows forms project and several class-library projects- when i debug this solution, the debugger moves well from the forms project to the dll project--the classes in this are not serviced components - all is well in this scenario >> but, when a solution has a windows forms project and several class library projects, where all the classes are ServicedComponents (System.EnterpriseServices), when i step thru, I am forced to to attach to the process for each dll project. It is a major pain to do this every time. Is there a way to automatically attach to all the processes of all the dlls in my solution, when the dlls contain classes that are serviced components. >>when i use vb6 and com+, my vbg (vb group file) has 100 forms and 10 dll projects- each dll project has several classes and each class requires transaction. In this scenario, the vb6 debugger nicely steps thru from the form code to the dll code- without having to attach to any processes- i want to be able to do this in vs.net 2003 - C# >> thanks to all for your time and comments thanks ranga raghuram Tag: Text not being displayed in a Msgbox Tag: 82261

    - Tabbing between VS.NET style floating panes I am writting a windows application in .net. This is an MDI application, very similar to VS.Net, so it has dockable panes etc. When those panes are floating, I would like to use some hotkeys to tab between them. Is there a standard hotkey to do this or I would have to write some code? Thanks. -D Tag: Text not being displayed in a Msgbox Tag: 82260

    - MessageBox and Focus I have a message box that pops up when there is a problem after a user clicks on a button. After the user clicks OK on the message box, I need the focus to return to a different control (a textbox). Intuitively, you would think the line MyTextbox.Focus after the MessageBox.Show line would do the the trick. Howerver, focus always returns to the control that initiated the show method. Any focus method after that is ignored. Can anyone tell me how to overide this behaviour? -- wr Tag: Text not being displayed in a Msgbox Tag: 82247

    - Watcher of called methods in C# Hi could you help me to find out how can I watch which method is called in some object? I would like to do functionality that shows in dialog window (Windows forms) a proggres bar while in backgroun window runs some functionality like loading or updating data in form. Yes I can do this by showing Wait cursor to users but this is for me not enought.;) I would like to do that easiest as posible for implementation on existing code. So I have some idea to have a "listener" thats hooks on Form object and listen to method calls with specified custom Attribute on methods that are doing loading or other app freeze functionality. And I look if a method has my attribute and if is true I show up dilaog window with progres bar. Could you help me find out which object can listen to method calls or if you have some other solution on my problem? Thanks a lot Frankie Tag: Text not being displayed in a Msgbox Tag: 82243

    - Control Addition safety handling I was curious about the following scenario but couldn't find the exact handling using disassembler: What happens if an instance of a control already added in the Controls collection of a form is added again? Is there a reference check on each control addition to handle the said scenario? It is possible that there is a reference checking since the OnControlAdded event is not raised for the second time. Anyone who can shed some light on the said handling? Thanks a lot! Tag: Text not being displayed in a Msgbox Tag: 82239

    - Label with Transparent Background I need to have text displayed over a picturebox with an image in it. When using a label whose BackColor = System.Drawing.Color.Transparent, the background is not transparent. I came across this explanation as to why .Net does not support transparent backgrounds. ************ [In Visual Basic 6.0, the BackStyle property of the Label control determined whether the label had a transparent background. Setting the BackStyle property to 0 â?? Transparent allowed any background image or other controls to show through the label. In Visual Basic .NET, the BackStyle property no longer exists, and the transparency behavior is slightly different. To emulate the transparent behavior in Visual Basic .NET, set the BackColor property to System.Drawing.Color.Transparent. This will allow the background image to show through, but it will not be transparent in regard to other controls.] ********************** The last phrase is mindboggling, " . . . but it will not be transparent in regards to other controls." What good it is then??? Why would any lanquage designer not support such a useful property? How do I get a label to have a true transparent background??

    - Inheritance in forms which inherit template forms I have this "template" form which is based on System.Windows.Forms.Form. I created a new form(the derived form) which inherits this form. I have observed that if, at runtime, I run through all of the controls in the controls collection of the "template" form, I can have access to all the controls that exist in the derived form! Now this seems odd to me; why should a base class have the controls of a class above it (the derived form), in its controls collection. Certainly I would expect the class derived from the template to see all the controls on the base class but not the other way around. -- Michael Hockstein Tag: Text not being displayed in a Msgbox Tag: 82235

    - Problem with FileSystemWatcher/Tray Notifier App Hi, I've been developing an application in VB.NET that uses the FileSystemWatcher and a popup notification in order to tell me when files have been downloaded. The FileSystemWatcher code in my project is basically the same one thats floating all over the VB.NET sites (by Jayesh Jain). The popup notification (called TaskbarNotifier) is a class originally by John O'Byrne written in C# and C++ but ported to VB.NET by Patrick Vanden Driessche. It was downloaded from codeproject.com. Both of these elements (FileSystemWatcher and TaskBarNotifier) work perfectly on the own but I experienced problems when I tried incorporating and combining them in my own project. Basically, the FileSystemWatcher will detect files created, changed, deleted etc and the TaskBarNotifier will display popups as it should. The problem comes when I create a file (by means of downloading it or by just copying it to the 'watched' folder directly). I've coded it so the TaskBarNotifier should popup with name of the file created/downloaded then disappear after 3 seconds. It should, but doesn't. I can't understand why the same code will not run when used under a different procedure. I would of prefered to paste the code here in the hope people willing and able to help can paste it directly into their own VB.NET environment but the project contains bitmaps (as Embedded Resources) for the skins of the popups and they need to be included when compiling/testing the app otherwise it won't compile. So for this reason I've posted the project on my website for download. Homepage: http://www.geocities.com/toffee_paul/fun_d_mental.html Direct Link: http://www.geocities.com/toffee_paul/vbnetproj.zip When compiled and the form is displayed, click 'Test just the Popup' and the popup will appear as it should. Now change the 'watch folder' to a valid folder and copy a file to this folder. The app will detect the newly created file (as proven in the 'content' textbox) but the popup will fail to appear. Very strange problem. Any help is very much appreciated, Thanks Paul Tag: Text not being displayed in a Msgbox Tag: 82232

    - Webbrowser Hide Bug (Solution) I don't think anybody has ever come up with a satisfactory solution to the bug where the webbrowser control, hosted in an MDI child, breaks when the form is hidden and reshown. I think this problem also sometimes manifests itself in non-MDI forms too. The solution I came up with was very simple and seems to work perfectly. State is maintained perfectly and you don't have to reload the page or anything. 1) Wrap the webbrowser control in your own UserControl (I recommend the WebOCHostVB... search for it in MS KB... Article ID 311303). 2) In the usercontrol's HandleDestroyed event remove the webbrowser from the Controls collection (and add it back in the HandleCreated event). This prevents the orphaning of the webbrowser window. Private Sub WebOCHostCtrl_HandleDestroyed(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.HandleDestroyed 'detach the browser If Not webBrowser Is Nothing Then If Me.Controls.Contains(webBrowser) Then Me.Controls.Remove(webBrowser) End If End If End Sub Private Sub WebOCHostCtrl_HandleCreated(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.HandleCreated 'attach the browser If Not webBrowser Is Nothing Then If Not Me.Controls.Contains(webBrowser) Then Me.Controls.Add(webBrowser) webBrowser.Width = Me.ClientRectangle.Width webBrowser.Height = Me.ClientRectangle.Height End If End If End Sub That's it!

    - Resource Files, Satellite Assembly - newbie This has been bothering me for the last couple of hours. Here is what I would like to do. I want to create a sample when a button is clicked, depending on Culture I would like to display the flag. What I did was create a resx file using ResxResourceWriter and AddResource Method. I included few countries' flags in the resx file. I used resgen to create the .resource file. I am using the following lines of code: rm = New ResourceManager("MyImages", Me.GetType().Assembly) and PictureBox1.Image = CType(rm.GetObject("MyImage", ci), System.Drawing.Image) Using the reseditor I could see the bitmap files in the file. When I run the sample I keep getting the error - ********************************************** An unhandled exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll Additional information: Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure "MyImages.resources" was correctly embedded or linked into assembly "ResourceFileSample". I tried including the .resources file in the peoject, compiled but still got the same error.

    - Detect when owned form is brought to front? Sorry about the last post -- I hit Enter by accident... I have the following code ('this' is a non-MDI Form): Form form1 = new Form(); form1.Owner = this; form1.Show() Form form2 = new Form(); form2.Owner = this; form2.Show(); The behavior is that form1 and form2 are sort of child forms of 'this' form. When the above code is executed, form2 is in the front, and I'd like to check when the user clicks on form1 to bring it to the front. I guess I was assuming that this was the 'GotFocus' event but this does not work. Is there a 'ZOrderChange' event, or what is it? Thanks. Tag: Text not being displayed in a Msgbox Tag: 82213

So...I wonder is there anyway to check the performance of "Smart Client". I just want to optimize my app's code to enhance performance.

    - mdi client problems - second try In our app (VB) client forms are displayed based on what is on the current client form and the button pressed. A user never selects a client form. You can think of this process as filling out a very long form with many branches (e.g., IRS form 1040). Once a client form is loaded it is never unloaded - just hidden. I need help resolving these 2 problems: 1) Focus on a text box. I know i can't set the focus in the Load event but the Activated event only fires when the first client loads. Also, when the form is redisplayed (i.e., made visible) txtbox.focus, for example, doesn't work. What I do now is start a timer with a 10ms interval and set the focus in the timer event. I also think that sometimes when I leave the text box the Leave event doesn't always fire. There's got to be a better way. 2) Client form size. I would like the client form to be the maximum size that will fit in the MDI parent. The minimum size of the client forms is set to 720 X 540. If i set the WindowState to Maximized the first client is displayed maximized but all the others are displayed at their minimum size. When the first client form is redisplayed it is also displayed at the minimum size. This just drives the users crazy. What I've done is after showing the form the first time or making the form visible on redisplays I set the child.Dock = DockStyle.Fill. I also do this if the parent is resized. Now the client is almost maximum size except it still has its own margins. -- tsiGeorge Tag: Text not being displayed in a Msgbox Tag: 82203

    - changing look and feel of an app I would like to know if there are any examples, tutorial on how to completely change an application's look and feel. By that I mean the colors, the way menus are drawn, the way tool bar items are spaced in a tool bar, the way tab identifiers are shaped, etc., etc. There are a few interesting 'LAFs' such as MS Money 2005, MSN Messenger 6.2, Office 2003...just to name a few basic ones. I would like to have one of my graphic designer friends do a mock up in photoshop then produce an application that looks like it (I'm assuming it all has to be done programatically so designers would have to resort to something like photoshop). I also understand that part of the reason the aforementioned applications look the way they do is because of controls which are not available publicly...despite that, if designer can create websites (with primitive components) that can draw powerful and diverse emotional reactions, I don't understand why rich client GUIs have to look so ugly and gray (obviously 'consistency' has its place too). Any way, it will be even better if someone can point me to publicly available LAFs, the way we are starting to see them for the Java/SWING community. Thanks!

    - A Bug in .NET Framework/Windows Forms Anyone who sees this We have been grappling with this problem ever since we ported to .NET. Microsoft says that MenuItem event handlers are not garbage collected, since they are not "closely tied" to the forms. Although they keep holding the refrence to the forms and it causes the forms to not dispose. So the user objects and GDI object counts keep riising. Apparantly they dont think its an issue and the users have to add handlers for menu item events and then remove the handlers manually. If anyone has come across this issue and know of any other solution besides Microsoft's then please post it. Tag: Text not being displayed in a Msgbox Tag: 82166

    - ICustomTypeDescriptor.GetEditor - Which property am I on?? I have a class that will be edited via the CollectionEditor/CollectionForm UI. To that extent I have defined the various properties I want editable for my class. However, three of the properties are of type string but I would like them edited by selection from a dropdown list whose contents are determined at runtime. It looks like I might be able to use the ICustomTypeDescriptor interface to do what I need. In particular, if I could override the GetEditor method to create a specialized UITypeEditor for these three properties then I think this would do the trick. The only problem is that I cannot see how I know, when GetEditor is being invoked, which property it is being invoked for! Thanks, -- TB Tag: Text not being displayed in a Msgbox Tag: 82165

    - How to select datagrid cell This sounds very simple, but I'm having trouble getting it to work. When I display a WinForms datagrid, I want the value in the first row and column to appear in reverse image. I have tried setting the CurrentCell, focusing the grid, getting the textbox and tried to select the text, etc. Each time with no luck. When I press the Tab key to tab through the cells, then the cells are reverse-imaged. But I need it that way on initial display. Tag: Text not being displayed in a Msgbox Tag: 82164

    - Simple Data Grid DataSource Problem I want to use a data grid in a MFC Project. After adding the grid to an empty dialog, I did not find a way to connect to a data source: The DataSource textbox stays empy (I added all kind of Connections and Commands). The help systems says that ADO is to use, but if found only Microsoft ADO Data Control 6.0 (SP6.0) (OLEDB) and if I add this to the dialog I get: "File or assembly name AxInterop.MSadodclib.dll or dependency was not found". What can I do? Tag: Text not being displayed in a Msgbox Tag: 82163

    - CollectionEditor: How to turn on "description" panel? If I use a PropertyGrid directly, the "description" panel is available and can be turned on and off and resized, etc. But if I use a CollectionEditor, the property grid displayed there doesn't appear to honor the request to display the "description" panel even though the properties of the items in my collection all have description attributes. How can I get the description panel for the property grid portion of the CollectionEditor to be displayed? Thanks! -- TB Tag: Text not being displayed in a Msgbox Tag: 82161

    - CollectionEditor: How to specify arbitary list of values for prope I have a collection of items that I allow the user to edit by bringing up a CollectionEditor. The editor conveniently displays all the properties of my item class and works pretty well. However, I am changing one of the properties from being of an enumerated type to being a string value that should be set from a list of possible values determined at runtime. The enumerated value is automatically handled by the PropertyGrid as a dropdown list. How can I override this behavior to supply the list of allowed values at runtime? I have been successful at plugging in my own derivation of a UITypeEditor for this property but I cannot figure out how to supply the instantiated type editor the list of values to display in the dropdown.

    - Scrolling during a Drag Operation Hello all, I have a UserControl that is in a Panel. The Panel's AutoScroll is set to true. When the user drags data over the Panel and hits the edges, I want the control to scroll. I've managed to get this all to work. But I have a few questions: - Is there a standard distance from the edge of the window that the mouse should be before scrolling starts? - How much does one scroll each instance? I've tuned mine to match the speed of the machine I'm doing development work on... Obviously this may not work for others. And one technical question. To do the scrolling I adjust the AutoScrollPosition property while handling the OnDragOver event. If I do this every time the OnDragOver event is fired, my scroll bars move, but nothing is re-drawn (until the scroll bars go as far as they can). On the other hand, if I update the auto scroll position every other time OnDragOver is fired, then everything works as expected: the scroll bars move and the panel is updated. This seems odd, and I find no details on this in the documentation or in a search of the newsgroups. One other question. What is DragDropEeffects.Scroll used for? Is there any point to it? Or is it just there in case you want to change cursors. Finally -- I'm doing my scrolling in OnDragOver. Should I do it in GiveFeedback instead? I'm a little unclear how the framework expects me to seperate the tasks (currently, since I have no special cursors, I do implement GiveFeedback). Cheers, Gordon. Point mouseCurrent = PointToClient(new Point (drgevent.X, drgevent.Y)); /// /// Is it time to scroll (if possible)? Skip every other call to give /// the rest of the update framework a chance to catch up. /// //// _lastDidIt switches from true to false on each call, it is a method variable. int dragboarder = 20; int dragscrolldist = 5; if (mouseCurrent.Y > Height-dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X, -AutoScrollPosition.Y+dragscrolldist); } if (mouseCurrent.Y < dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X, -AutoScrollPosition.Y-dragscrolldist); } if (mouseCurrent.X > Width-dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X+dragscrolldist, -AutoScrollPosition.Y); } if (mouseCurrent.X < dragboarder) { if (_lastDidIt) AutoScrollPosition = new Point (-AutoScrollPosition.X-dragscrolldist, -AutoScrollPosition.Y); } _lastDidIt = !_lastDidIt; /// /// Make sure everything is re-drawn. /// Invalidate(); Tag: Text not being displayed in a Msgbox Tag: 82150

I was trying to create a simple Hello World application with .Net and when
the Message box appears it is blank. There is no text visible on the form or
on any of the buttons. If you have any ideas how to fix this problem I would
appreciate it.

This is a McAfee VirusScan problem that NAI is aware of and that can be
fixed by installing a patch:
