    - FontDialog Only Allows Integrals? I've noticed that the FontDialog only allows positive integers as input when you show the dialog. Is there some reason for this? The font that it returns allows singles and I can't really find anywhere that explains why this might be. We're writing our own FontDialog (due to some other limitations), and we're trying to find out if there is a practical reason for this or if we should allow any positive decimal number. Thanks.

    - drilling down in a datagrid I have a datagrid with a dataset as its datasource. Its datamember is a table that has 3 datarelations defined in the dataset. I would like to capture the click event on the plus sign to avoid allowing the user to select which datarelation to use to view child records. Can I do this without subclassing the datagrid? If not, what is the best way to grab onto the plus-sign click (since datagrid.hittestinfo doesn't distinguish the plus-sign click from any other rowheader click)? Thanks for the help. -- Pat Tag: Draw one label on top of another Tag: 102811

    - ANN: Dialog Workshop .NET - powerful dialog components Powerful replacement of the standard .NET dialog components. Dialog Workshop .NET contains dialog components which you can use (instead of standard .NET components) to extend Windows common dialogs without writing a line of code! For example, you can add preview pane in Open/Save dialogs in 10-15 minutes using your own .NET Windows Form! Many new features which do not exist in original .NET dialog components are available: a. Extending dialog window using your WinForms; b. Custom dialog items captions, startup position and icon; c. Design-time preview; d. Separate tab in FileOpen dialog with MRU list similar to VB6 file dialog; e. Supported dialogs: Open/Save, Browse For Folder, Print, Page Setup, Font, Color, Run, Pick Icon and Shell About dialogs. New Ver.1.4.5 feaures: - New OkButtonRect and CancelButtonRect properties; - New Resize event has been added. - New CustDlgParams.Size, CustDlgParams.Location properties can be used to specify exact dialog's position and size. - New TabCaptions property allows you to set custom captions for Browse and Recent tabs in Open/Save dialogs; - Native .NET 2.0 assembly included (compiled using Visual Studio 2005). New Visual Studio 2005 samples. Homepage: http://www.componentage.com Best regards, COMPONENTAGE Software Team Tag: Draw one label on top of another Tag: 102800

    - Custom title bar size in Non-client area Hi! I am trying to make a custom size title-bar in the non-client area of the form. I've tried hooking to the NCCALCSIZE message with this code: case (int)Native.NativeMethods.WindowMessages.WM_NCCALCSIZE: if (m.WParam == IntPtr.Zero) { // get the NCCALCSIZE parameters NativeMethods.NCCALCSIZE_PARAMS csp; // Marshal them from the pointer csp = (NativeMethods.NCCALCSIZE_PARAMS)Marshal.PtrToStructure(m.LParam, typeof(NativeMethods.NCCALCSIZE_PARAMS)); // Resize the client area to make more room above csp.rectBeforeMove.top-= csp.rectBeforeMove.top/ 2; Marshal.StructureToPtr(csp, m.LParam, false); } else { base.WndProc(ref m); } return; However, it just says that I am trying to read or write into a protected memory. If i modify any other value, i.e. right, left or bottom of the same rectangle, it works OK yet there are no changes. I also tried changing the other two rectangles, but the result is never what I need. I would really appriciate any suggestions on this topic. Tag: Draw one label on top of another Tag: 102799

    - Bug in SaveFileDialog Hello there, I found a bug using SaveFileDialog and I was not able to find any similar issue on the web. This seems to apply to any .NET Applications using SaveFileDialog. To perform the bug: 1. Open a SaveFileDialog and save any File, e.g. TestDocument0.txt: This should create a document named TestDocument0.txt 2. Call once again the SaveFileDialog, select the TestDocument0.txt you created in the File Window: The name of the File appears in the Text Box, left of the "Open" Button. (Notice, the Selected File is still grayed in the File Window) 3. Rename the Text in this Text Box, e.g. TestDocument1.txt: (Notice, the Selected File is still grayed in the File Window) 4. Click in the File Window, but not on a folder or a file. The previously selected File is not grayed anymore, the focus is set on nothing. 5. Press the "Save" Button, you will get the following Waning: "File TestDocument0.txt already exists. Do you want to replace it" The error is obvious, it should save my file as TestDocument1.txt, and not TestDocument0.txt, as it appears on the Text Box. Could you reproduce such strange behaviour?

    - usercontrol with readonly property that can be set at design time Can someone tell me if it's possible to create a property for a usercontrol, that is essentially readonly, but able to be set via the designer before runtime? I have a property for a control that I want to set essentially one time. This property is basically a static property that can change at the developer's wish, but only one time. I need to be able to reference the property later. I've tried setting the property to readonly, but that hides it from the designer properties window. I've tried various attributes to no avail (i.e. DesignOnly(true)). When I do this, I cannot set the property at design time(the value doesn't hold). But in later code I can change that property without fail. I'm confused. Please help. Tag: Draw one label on top of another Tag: 102766

    - BackgroundWorker and RunWorkerCompleted event I have a BackgroundWorker component that I am using as: Dim arguments As XmlSentArguments = New XmlSentArguments arguments.TransactionId = 10 arguments.OrderId = "na" workerThread.RunWorkerAsync(arguments) The thread seems to get started and it completes. I put a breakpoint in DoWork that looks like: Dim worker As BackgroundWorker = _ CType(sender, BackgroundWorker) e.Result = BackgroundXMLSent(e.Argument, worker, e) Since I am not interested in cancelation or progress the BackgrounXMLSent routine just looks like: Function BackgroundXMLSent(ByVal arguments As XmlSentArguments, ByVal worker As BackgroundWorker, ByVal e As DoWorkEventArgs) As String Return XMLSent(arguments.TransactionId, arguments.OrderId) End Function I have verified in the debugger that the routine XMLSent is returning so BackgroundXMLSent is returning. The problem is the the event RunWorkerCompleted does not get fired and the component always shows IsBusy as True. Any ideas as to why this event is not firing and why the component is always busy after the first call? Thank you. Kevin Tag: Draw one label on top of another Tag: 102765

    - Accelerator keys broken in Winforms I'm having a problem with accelerator keys (also sometimes refered to as shortcut keys or mnemonics) on Winforms. To reproduce, simply do this: 1. create a new C# "Windows Application" project (I'm using VS2005) 2. Add a button to the form and change its default Text from "button1" to "&button1" Now run the app. Press the alt key on the keyboard and the keyboard cue is displayed (the 'b' becomes underlined) as it should. Press the alt key again and the underline does not go away. You will also notice that pressing the 'b' key fires the button's click event regardless of whether the alt key was ever pressed, or whether the cue is visible. Surely this isn't "by design" (Menus don't work this way! OS supplied dialogs don't work this way!) Any pertinent suggestions on how to work around this would be welcome.

    - Getting Icon of Files All - How can I get an icon associated with a particular file extension and then get the icon displayed in a picturebox? I have an app with a picturebox. The picturebox displays pictures and other files stored in SQL. If the SQL data is an image, it displays the image but if it is, say a word doc, it displays an image I created that says "Not an Image". I would like to display the icon associated with the particular file type inspectead. So, when a user adds a word doc, the icon is shown in the picturebox or adobe or whatever else the user might save to the database. Better even yet, would be to load a preview of the document into the picturebox, like Adobe does in the "thumbnail" view of a windos folder.

I want to capture all form details for a given form at design time (properties and controls) but I can't find anyway to do it.

    - How to create responsive drag and drop experience even if lots of processing is required I have a winforms application that can encrypt and unencrypt files. I want to support drag and drop files out to Windows Explorer. In my current version I unencrypt my files in the MyListview_ItemDrag Event, build an array of files and call DoDragDrop() with DataFormats.FileDrop. This works, but I'm concerned about this architecture. If a user starts to drag several files from my listView and all of these files are really BIG. It can take some time to unencrypt these files and place them in a directory. Meanwhile the application thread is busy and the application seems unresponsive to the user. As far as I know, no DragDrop-like Event will trigger in my code when I drop in an external app like Explorer. So is there no way to postpone the time-consuming part (unencrypting files) to the DragDrop part when the user releases the mouse button?? I hope I'm wrong. Any tips, suggestions?

    - User control life cycle in VS2005 editor Hi, Can someone tell me what is the user control life cycle when its dropped in to a visual studio designer? I mean, I have a new windows application project created in visual studio 2005 and a new form added. Now I create a new user control extending it from UserControl. Add few properties in user control and few events. Now when I drop this user control in form, i want to know what designer does to display it on the form and what event's would be fired and which events wouldn't fire . Reason of asking such question is, I have a user control and when i drop it on a form, it fires its load event and I was under impression, it would not fire load event when control is in design mode. It must fire it when its in RunMode. I do check DesignMode property but it seems like its not giving me right value. Or do i have to implement any other interface with user control to make DesignMode property work in right way? Thanks, Hiten Tag: Draw one label on top of another Tag: 102706

    - DataGrid and business objects I would like to display/edit an ArrayList of objects in a DataGrid. Each row in the datagrid displays a Machine. Problem 1: Each of the objects (Machine) in the list has an ArrayList of child objects (Part). How must the following example be rewritten so that it doesn't produce this exception: System.ArgumentException: The data grid table styles collection already contains a table style with the same mapping name. Problem 2: Each of the Machine objects has a reference to a Manufacturer object, which contains the property Name.

Is it possible to display the manufacturer name in the grid, so that 4 columns are displayed (Model, ID, Price, Manufacturer name)? using System; using System.Drawing; using System.Windows.Forms; using System.Collections; public class Machine{ private string model; private string id; private decimal price; private Manufacturer man; // Use an ArrayList to create a related collection. private ArrayList parts = new ArrayList(); public string Model{ get{return model;} set{model=value;} } public string Id{ get{return id;} set{id = value;} } public ArrayList Parts{ get{return parts;} set{parts = value;} } public decimal Price{ get{return price;} set{price = value;} } public Manufacturer Man{ get{return man;} set{man=value;} } } public class Manufacturer{ private string name; public string Name{ get{return name;} set{name=value;} } } public class Part{ private string partId; public string PartId{ get{return partId;} set{partId = value;} } } public class DataGridSample:Form{ DataGrid myGrid; static void Main(){ Application.Run(new DataGridSample()); } public DataGridSample(){ InitializeComponent(); } void InitializeComponent(){ this.ClientSize = new System.Drawing.Size(550, 450); myGrid = new DataGrid(); myGrid.Location = new Point (10,10); myGrid.Size = new Size(500, 400); myGrid.CaptionText = "Microsoft .NET DataGrid"; this.Text = "C# Grid Example"; this.Controls.Add(myGrid); BindToArray(); } private void BindToArray(){ Manufacturer man1=new Manufacturer(); man1.Name="Man.1"; // Create an ArrayList of Machine objects (defined below). ArrayList Machines=new ArrayList(); Machine tempMachine; tempMachine= new Machine(); tempMachine.Model = "AAA"; tempMachine.Id= "A100"; tempMachine.Price= Convert.ToDecimal(3.80); tempMachine.Man=man1; Machines.Add(tempMachine); // The first Machine includes an array of Part objects. Part p1 = new Part(); p1.PartId= "PartX"; Part p2 = new Part(); p2.PartId= "PartY"; // Note that the Machines.Parts property returns an ArrayList. // Add the parts to the ArrayList using the AddRange method. tempMachine.Parts.AddRange (new Part[]{p1, p2});; tempMachine= new Machine(); tempMachine.Model = "BBB"; tempMachine.Id= "B100"; tempMachine.Price=Convert.ToDecimal(1.52); Machines.Add(tempMachine); tempMachine= new Machine(); tempMachine.Id= "CCC"; tempMachine.Model = "B100"; tempMachine.Price= Convert.ToDecimal(2.14); Machines.Add(tempMachine); myGrid.SetDataBinding(Machines, ""); CreateTableStyle(); } private void CreateTableStyle(){ // Creates two DataGridTableStyle objects, one for the Machine // array, and one for the Parts ArrayList. DataGridTableStyle MachineTable = new DataGridTableStyle(); MachineTable.MappingName="ArrayList"; // Sets the AlternatingBackColor so you can see the difference. MachineTable.AlternatingBackColor= System.Drawing.Color.LightBlue; // Creates three column styles. DataGridTextBoxColumn modelColumn = new DataGridTextBoxColumn(); modelColumn.MappingName= "Model"; modelColumn.HeaderText= "Model"; DataGridTextBoxColumn IdColumn = new DataGridTextBoxColumn(); IdColumn.MappingName= "Id"; IdColumn.HeaderText= "Id"; DataGridTextBoxColumn priceColumn = new DataGridTextBoxColumn(); priceColumn.MappingName= "Price"; priceColumn.HeaderText= "Price"; priceColumn.Format = "c"; DataGridTextBoxColumn manColumn = new DataGridTextBoxColumn(); manColumn.MappingName= "Man.Name"; manColumn.HeaderText= "Manuf."; // Adds the column styles to the grid table style.

DataGridTableStyle partsTable = new DataGridTableStyle(); partsTable.MappingName="ArrayList"; //IF YOU UNCOMMENT THIS LINE, AT LEAST THE MAIN ARRAYLIST IS DISPLAYED DataGridTextBoxColumn partIdColumn = new DataGridTextBoxColumn(); partIdColumn.MappingName= "PartID"; partIdColumn.HeaderText = "Part ID"; partsTable.GridColumnStyles.Add(partIdColumn); myGrid.TableStyles.Add(partsTable); } } Tag: Draw one label on top of another Tag: 102701

    - Wizard generated code doesn't display data from database. I am sure this is an FAQ but I could not find it and I was wondering if someone could help me. I wanted to quickly generated a view of a couple of tables in our database. I pulled up the wizard and generated a couple of data sets and data adapters. The wizard inserted for the DataGridView the following code: Me.AmazonOutbound2TableAdapter.Fill(Me.TestServiceBusDataSet.AmazonOutbound2) I look at the dataset and the dataset is indeed getting populated (I stepped into the debugger and examined the data after this line was executed). The problem is that the data grid view does not show the data. How do I make the data grid view show this data? Also I would like to display only a subset of the data maybe by adding a where-clause constraining the data returned by one of the column values. I see a command set but it seems to be read only. How would be the best way to dynamically change the command set that is used for the selection? Thank you. Kevin Tag: Draw one label on top of another Tag: 102699

    - Currency Manager returns last ComboBox item row I've made something like that: private void comboBox1_SelectedIndexChanged(object sender, System.EventArgs e) { CurrencyManager cm = (CurrencyManager) this.BindingContext[((ComboBox)sender).DataSource]; DataRow dr = ((DataRowView) cm.Current).Row; MessageBox.Show( dr[0].ToString()); } comboBox1 is binded like this: DataTable dt = new DataTable("table"); DataColumn ix = new DataColumn("ix",System.Type.GetType("System.String")); DataColumn iy = new DataColumn("iy",System.Type.GetType("System.String")); DataRow dr ; dt.Columns.Add(ix); dt.Columns.Add(iy); dr = dt.NewRow(); dr[0] = "asterix"; dt.Rows.Add(dr); dr = dt.NewRow(); dr[0] = "abladabla"; dt.Rows.Add(dr); comboBox1.DataSource = dt; comboBox1.DisplayMember = "ix"; The result is that if I choose abladabla from combobox, the sterix value is displayed in a messagebox -> The last selected row is returned by the code in SelectedIndexChanged. Don't know how to make this work "normal". Simply: I choose asterix -> it displays asterix, I choose abladabla or whatsoever, it displays it. Tag: Draw one label on top of another Tag: 102698

    - Resizing a form to shrink or grow according to the controls that are added Hi all, I realize this should be obvious, but I don't know what I'm not doing. I have a form to which I add a variable number of controls. All I need the form to do is to shrink or grow according to the size of the controls added. I suppose I could manually calculate the dimensions that the controls occupy and then manually set the Form's dimensions. But there has to be a more automatic way - I thought the AutoScale property being true would handle this, but I think that only scales the controls as the Form is resized - not vice-versa. Thanks for any suggestions, Novice Tag: Draw one label on top of another Tag: 102688

    - App on Web server will not Run I have a winforms application that I placed on the internal web server for "no touch" deployment. The application will run from the web server when I am logged in and on other "regular" users pcs for the most part. On two person's pc's, the application will not load. It doesn't seem to do anything when I point the browser to the exe located on the web server. I double checked the .net security configuration and it has been granted fulltrust for intranet applications. Does anyone know what might be causing this?

    - combo box data is there, but it's not displaying I'm using vb.net 2003. i have a windows form with a drop down list box. If i click on a "row" in the drop down, it finds the data and all is well. the problem is, the data is not displaying on the drop down. it's there, but not displaying. if i run it from vb.net, in debugger mode, it shows up. when i compile to release and run the exe, it does not show up. at one time i found a patch for this. it was a dll that needed to be replaced. my box blew up on my last week and I've can't find that patch to fix this. Can someone please point me in the right direction. Thanks -- Shannon Ramirez Network DBA Tag: Draw one label on top of another Tag: 102670

    - .NET 2.0 and System.Configuration.ApplicationSettingsBase Hi all, I think that ApplicationSettingsBase class on .NET 2.0 framework is very useful and easy to use, in order to store global and personal paramenters for a winform application. The only behaviour that I don't like is where it saves updated user settings. AFAIK it saves a file called: <document and settings folder>\<userfolder>\Local Settings\Application Data\<companyname>\<applicationname>_StrongName_n5qhp1elc4gnqe1a1bida0iqjryk1mun\<applicationversion>\user.config Anyone knows hot to customize/change this default location/name? I would like to have something without the "strong name" part, like: <document and settings folder>\<userfolder>\Local Settings\Application Data\<companyname>\<applicationname>\<applicationversion>\user.config thank you in advance for your help.

Hi all, is there a simple way to draw one label on top of another?

Or does this require overriding OnPaint?

Thanks,

You'd propbably be better off deriving a control from Control and creating
your own label with a transparent background.
