    - resize panels smoothly Hi, I have a windows form with a button and 2 panels. All Panel.Dock = DockStyle.Left ------------- | | | | 1 | 2 | | | | ------------- When I click on the button, I want panel 1 to shrink and panel 2 to grow in width: int i = p1.Width; p1.Width = p2.Width; p2.Width = i; this.Refresh(); My question is... how to make the shrinking and growing animation look smooth and not flickering on the monitor? I tried to use timer, but it's completely unacceptable for user's experience. Please help! Thanks, Ching-Lung Tag: DataGrid row icons Tag: 53355

    - WebBrowser ctrl: switch off context menu in C#? Hi, I am using the AxSHDocVw.AxWebBrowser web browser control in my windows forms application in C# and I would like to switch off the context menu of the browser. Currently, I only found a solution for c/c++: It seems that one has to implement the IDocHostUIHandler interface, which should be defined in the mshtml assembly. Apparently, it is not there. Any ideas? Other solutions welcome as well! Thanks in advance, Guenter Tag: DataGrid row icons Tag: 53345

    - Long drawing loop cancellation Thinking about a standard "silly" problem of giving a user an option to cancel long drawing loop, I read a lot of articles and did some investigations of my own. (I work with C# .Net 2003). My application must provide a very sophisticated drawing, which is actually a millions-length sequence of simple line or ellipse drawings executed in a very long loop. Naturally, I'd like to give a user an option to cancel the drawing. I have a number of rather bad solutions and I don't see any acceptable one. The Solutions are: 1. The drawing loop is execute in the UI thread and calls DoEvents() to allow "Cancel" button to be pressed. The downside is well known (see DoEvents() method adoption discussions) ? UI thread is busy and natural events sequence is broken. 2. The drawing loop is executed not in the UI thread. The downside is seldom exceptions. Generally, as I know, .Net does not allow drawing from non UI thread. 3. The drawing loop is executed not in the UI thread but all drawing operations are executed in the UI thread by calling Invoke for each elementary drawing operation. Theoretically, this must be the correct schema! . The downside is that Invoke() is a very expensive call, so it works inappropriately long (see table below). 4. Using memory-stream metafile for buffering. Actually, this is not what I need; in addition, it works even longer then #3. Here is the execution time comparative graph for different implementations of a loop with 2,000,000 drawing lines on my PC. 1. Execution in the UI thread (without DoEvents() calling) - time 00:00:04.6250592 (given as 1) and no "Cancel" available 2. Execution in the UI thread (calling DoEvents() on each step) - 00:00:10.5937500 (2.3 times longer) 3. Execution in a non UI thread (calling Invoke() for each drawing operation) - 00:05:41.560314 (73.8 times longer) 4. Drawing in memory-metafile (no DoEvents() or Invoke() ) - execution time 00:05:06.7153993 (66.3 times longer) Of course, 5 minutes instead of 5 seconds is too much for such a common task (a long loop cancellation). Any suggestions will be deeply appreciated. Alex Tag: DataGrid row icons Tag: 53342

    - Cannot find CrystalReportViewer control I did a full installation on VB .NET version 7.0 and .NET framework 1.0. I tried to find the CrystalReportViewer in the Toolbox but I couldn't. I also tried to look for it in Tools/customize toolbox but still weren't successful. Is it something to do with the VB .NET standard version or enterprise version? Also I found some control called CrystalReport, but it is not mentioned in the .NET document. What's the difference between this one and CrystalReportViewer? Thanks in advance.

    - Accessing System Menu from C# For a simple form without its own menu I wanted to add an "About..." command to the system menu as I would for an old MFC/C++ application. However I cannot find out how to access the system menu other than to toggle it on/off via the ControlBox property. Is this simply a .NET style being enforced (thou shalt not modify the system menu) or am I overlooking something? Thanks in advance! -- TB Tag: DataGrid row icons Tag: 53297

    - Newbie problem Hi, I'm having a problem with a windows application in VB.NET. It is an MDI application, and I have just added a splash screen that is displayed in the beginning of the constructor of the mainform, and then is hidden at the end of the constructor (after all the init is done for the mainform). The splash screen has a background image that fills all the form. There is also 4 labels on top the the background image. The problem is that for some reason, when the splash screen is displayed, the labels are not displayed. In fact, instead they act as if they were transparent, so I see whatever is behind the form on my desktop. Any idea what can I do for this? thanks, Ross . Tag: DataGrid row icons Tag: 53287

    - Transparency Problems I am attempting to wrap-up development cycle and have arrived at the point where "small annoyances" can no longer be avoided<g>. I notice that other applications windows (i.e. from other apps) "bleeding through" the UI from time to time. Now the "strange" thing is that the "underneath app" that always "bleeds through" is Internet Explorer. I am at a loss as to how to proceed since I have done nothing "knowingly" to enable any sort of transparency, all TransparencyKey values have been left to their default values.

    - Floating window for Office add-in? Hi, I'm developing a Microsoft Word add-in using VB.Net. It contains a custom non-modal dialog box, built from a Windows Form. The form should float above the active document in Word, similar to the behavior of the Find and Replace dialog in Word. In VB.Net, this can be achieved by setting the floating form's Owner property to the lower form: Dim Form as New Form2 Form.Owner = Me Form.Show() However, this doesn't work here since the "owner" is a Microsoft Word window, rather than a .Net Windows Form. Also, I can't just use the .TopMost property for my form, because that will cause it to float above _every_ window on the screen (including other applications.) Is there a way (probably through an API call) to make my form float above the active Microsoft Word document, but not other documents or applications? Thanks, Robert Jacobson Tag: DataGrid row icons Tag: 53284

I need to detect when changes are made to the DataSet by a particular form so that the user can choose to cancel or apply thoses changes (the Apply button is only enabled after a change is detected, e.g. after they alter a value and then tab out of the control). So I'm interesting in detecting changes made only to the DataRows that that form's controls bind to for a specific BindingContext. I've got it mostly working with one remaining issue. When there are multiple controls on a form that reference the same DataRow, I have not been able to detect a change to the row (e.g. when the user tabs to the next field) unless the control gaining focus does not reference the same DataRow as the control losing focus. What I've learned from my experimenting with it is that the RowState is not updated until I use EndEdit for the row. However, this only works after the "row loses focus." As long as the next control still binds to the same DataRow the DataRowVersion.Proposed doesn't exist and the EndEdit doesn't do any good. Please advise. Tag: DataGrid row icons Tag: 53279

    - Databinding combobox I have a windows form app that is bound to a dataview. If I add a combobox (with the default style of dropdown) and bind its text property to a field then everything is fine. If I now change the DropDownStyle to DropDownList then the binding no longer works (data from the back end SQL doesn't get displayed and if I select something in the combo then the update writes a null value back). I've tried binding to SelectedItem instead but that also doesn't work. Anyone come up with a solution to this one? -- Rob Oldfield www.realuk.co.uk Tag: DataGrid row icons Tag: 53272

    - Dataset Update che funziona in modo strano Ciao ho una piccola anomalia, in un dataset. Ho una form di dettaglio collegata con delle textbox a un database sqlserver tramite dataadapter, dopo aver generato il dataset e le stringhe sql per aggiornamenti e selezioni, mi si presenta il prblema. Tramite metodo fill riempio il database, e poi aggiorno tramite il metodo update soltanto che il database viene aggiornato solo se mi sposto al record successivo a quel punto riesco ad aggiornare il database. Mi sposto tramite bindingmanager, è normale che si comporti così. Insomma modifico e se salvo nulla, se mi sposto al record successivo e salvo mi salva il record precedente. Come mai? DaAccessori.update("DsAccessori,"T_Accessori"") e si comporta come vi ho detto mah. Grazie Ciao. Tag: DataGrid row icons Tag: 53260

    - CheckBox in DataGrid Hello all. I have place a CheckBox in a DataGrid using the following code: DataColumn dcInclude = new DataColumn("Include?"); dcInclude.DataType = System.Type.GetType ("System.Boolean"); dtParams.Columns.Add(dcInclude); The CheckBox column works and all is good, however, the CheckBox has 3 states. Ticked, un-ticked and grey ticked. Is it possible to have it so that the CheckBox only has 2 states (Ticked and un-ticked)? Thanks people, Jon Tag: DataGrid row icons Tag: 53256

    - Help please: RichText Control ActiveX and Load event Please can anyone assist: I try to use the Microsoft Rich Textbox Control 6.0 (SP4) on a winform dialog, since .NET's RichTextBox has problems with legacy components I have to use. I added the ActiveX control to the toolbox and successfully can add it to any Form I like, just like any other control. When the form the richtextbox is on is the main form of the application it seems to work ok, but as soon as I put it on a dialog's form which is modally shown via Form.ShowDialog() suddenly my dialog's OnLoad-event isn't called anymore ! I verified it by setting a breakpoint in VS.NET and even adding a MessageBox.Show(), but I can't get the OnLoad-Event to fire. Can anyone explain? Completely clueless, Martin Müller Tag: DataGrid row icons Tag: 53254

    - calling a form in a different project How do you instantiate and display a form that is in a different project within the same solution? I have a project full of Crystal Reports and one simple form (clientCrystalViewer) that displays them. It seems like I need to have the Reports in the same project as this clientCrystalViewer form so I can manipulate the dbconnection string dynamically (Its a Crystal issue). Rather than put everyting in one gigantic project (I've got 50 reports so far) I'd rather just call my clientCrystalViewer (really just a dialog box) from my project which holds all the rest of my forms. It seems to me that this should be possible and easy, but I can't find any documentation on it. Any ideas? Thanks Tag: DataGrid row icons Tag: 53253

    - I've fixed my problem. I had a problem with aspnet_wp.exe.I'm a newcomer to Web developement.I've just read first two lessons of: MCAD/MCSD Training Kit: Developing Web Applications with Microsoft Visual Basic .NET and Microsoft Visual C# .NET. I wasn't able to launch my WebForm from VisualStudio.Net Academic because I received: 1) aspnet_wp.exe could not be started. HRESULT for the failure: 80004005;2)aspnet_wp.exe could not be launched because the username and/or password supplied in the processModel section of the config file are invalid. from error log. Then I searched through Newsgroups and found: Subject: Re: Can't access CDO.Message From: "Lion Shi" <lionshi@online.microsoft.com> I must say that I tried only step 1 of recommended remedies below reported: *********************************************** Please try these steps: | > | > 1.

    - DataGrid Q: How to force a column to go muti line if necessary to handle the text I want to have all my columns visible in the window. I've found out how to disable the column resizing, and even to force the horizontal scroll bar to hide itself. What I dont know (if it can be done in the WinForms control) is how to force a cell to go multi line if necessary to show text. I've seen it done in the Web DataGrid. For the edification of everyone, here's how to disable column sizing, and hide the horizontal scroll bar. This, when combined with proper sizing of the columns, puts everthing on the screen for you: Do do any of this you must derive your own DataGrid and override stuff. To make the columns fixed (to prevent the user from increasing their size and necessitating a scroll bar) you must override OnMouseMove and OnMouseDown and stop it from calling the base class when a column resize is being done. To force the scroll bar to hide, hook into the VisibleChanged event and force it to hide there. public class MyDataGrid : System.Windows.Forms.DataGrid { public MyDataGrid() { this.HorizScrollBar.Visible = false; this.HorizScrollBar.VisibleChanged += new EventHandler(HorizScrollBar_VisibleChanged); } protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e) { DataGrid.HitTestInfo hti = this.HitTest(new Point(e.X, e.Y)); if (hti.Type == DataGrid.HitTestType.ColumnResize) { return; //omit base class call } base.OnMouseMove (e); } protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e) { DataGrid.HitTestInfo hti = this.HitTest(new Point(e.X, e.Y)); if (hti.Type == DataGrid.HitTestType.ColumnResize) { return; //omit base class call } base.OnMouseDown (e); } private void HorizScrollBar_VisibleChanged(object sender, EventArgs e) { if(this.HorizScrollBar.Visible == true) { this.HorizScrollBar.Hide(); } } } Tag: DataGrid row icons Tag: 53223

    - Windows Forms Dynamic Properties - Running on a Web Server???? I got in to a situation where we are planning to deploy our WinForms app in to a web server. We have dynamic properties already in it, and an XML file to read certain configurations. I know that this will give me an exception indicating that it could not find the the files locally. Is there a way to run a WinForms app that runs on the web with an app.config, and an XML file? If so, where would I be able to put it on the local machine. Tag: DataGrid row icons Tag: 53221

    - Events - publish/subscribe and GC'ing In my application the main thread my create several worker threads that will create additional objects. These additional objects become "publishers" and the main thread object (amongst others) then can "register" to receive the events. My question is, what happens when the "publisher" object completes it's work and disappears? Do I need to first broadcast a "please unregister" message to the subscribers? When the publisher goes away, if the subscribers haven't unregistered, will this create a leak and/or prevent the GC from collecting the now demised publisher object? Thanks!

    - How to associate icons with menu items Does anyone know a quick and easy way to place icon images in menu items of a MainMenu control? This is usually an effortless task for other controls using their ImageList properties, which is not available for MainMenu. The only way I can find is to set the menu item's OwnerDraw property to true and write code to handle the MeasureItem and DrawItem events. TIA for any input.

    - Splash Screen Problem Hi, I'm having a problem with a windows application in VB.NET. It is an MDI application, and I have just added a splash screen that is displayed in the beginning of the constructor of the mainform, and then is hidden at the end of the constructor (after all the init is done for the mainform). The splash screen has a background image that fills all the form. There is also 4 labels on top the the background image. The problem is that for some reason, when the splash screen is displayed, the labels are not displayed. In fact, instead they act as if they were transparent, so I see whatever is behind the form on my desktop. Any idea what can I do for this? thanks, Ross Tag: DataGrid row icons Tag: 53199

    - DataGrid row HasErrors I am creating my own DataGridTextBoxColumn class and I want to display an "Error" icon when the dataset row has errors. How would I check to see if a datarow has errors (.HasErrors) from the paint event of a DataGridTextBoxColumn class.

Hi, is it possible to get a handle to the icons used in a datagrid row? I
want to use the same icons on a button control.
E.g. The current selected row shows as a right arrow head and a new record
shows as an asteric (*), etc.

Thanks, Graeme
