    - RichTextBox Fields Hy, Is there any way (other than implementing it all by myself) to have text sections within a RichTextBox be only editable as whole sections? (namely, the user won't be able to select parts of a section and would only be able to delete the entire section) Thanx Tag: RichTextBox Fields Tag: 77988

    - Group icon blank when multiple dialogs are open In my application, if one dialog is open, the taskbar icon shows as the icon of the form. If multiple dialogs are open, then windows groups them under one icon in the task bar, but the icon is blank. The application definitely has an icon, as is show by the compiled executable. Does anyone know why it's blank? Tag: RichTextBox Fields Tag: 77983

    - Database independent application using C# 2003 Dear all I have to develop a database independent application in c# 2003. It means the underlying database should be anything like ACCESS, Oracle or SQL and my application should not get affected if i change between databases. i also have a requirement of storing 10,000 user records in my database. This database can also be created by our customers and weshould be able to use it. After reading ADO.NET i felt convinced that it is the solution for my requirement. But later i was thinking when i want to create a database independent application why i should use a database first of all, instead i can use XML. The following are the points supporting it. 1. XML universally accepted/standardized. 2. No hassle of connection to a database server, changing the DB adapters, customers having different databases facing problems in entering the data 3. Easily transferable and portable. Anybody can edit an XML file as there are lot of freeware available. The following are the points opposing it 1. Performance of parser while supporting 10,000 user records 2. Is it wise to think XML can be used in this way? Please help me out. Also from where can i get a sample c# applications storing the large user data (10,000 records) in XML file Ciao Hari Tag: RichTextBox Fields Tag: 77975

    - override of TreeView hi i want to override the windows forms tree view in a custom control in a way so the selected tree node does not center itself inside the tree view (is quite nasty if the tree view is scrollable, then you have to scroll back to get to the little + in front of the name). does anybody know which of the many focus methods i have to override for this purpose and how? regards gabriel Tag: RichTextBox Fields Tag: 77974

    - How to read All Data from SerialPort (2005) Hi, I'm experimenting with the Serial Port in VB.NET 2005. Although it isn't that easy to get any feedback from my COM-port as I thought it would be... How can I read all the Data that the port sends back? I tryed with SerialPort1.ReadLine, but that blocks the application and takes a lot of time (10 seconds!), I tryed SerialPort1.Read, but I have to read it into a buffer and has to indicate the count, but how do I know this? Does anybody knows a nice way to send and receive smoothly all the data from the SerialPort? Thanks a lot in advance, Pieter Tag: RichTextBox Fields Tag: 77973

    - 3-D FlatStyle is too flat! Hi, A System.Windows.Forms.Button with FlatStyle set to 3-D (Standard) is not 3-D enough for my application. Its hard to tell when the button is up or down. Users of my application need a strong visual feedback. Does anyone know if its possible to increase a Button's border width/thickness without overriding the Paint event and drawing the button manually? Thanks, Jeff Tag: RichTextBox Fields Tag: 77971

    - MdiChild - calling OnLoad() and OnActivated() i noticed the following behaviour in my MDI-Application: The order on wich the methodes OnLoad() and OnActivated() of a MDI-Child gets called first, depend on the value of the property WindowState of the Mdi-Child. If WindowState of a Mdi-Child has the value of "Normal", OnLoad() gets called bevore first call of OnActivated(). If WindowState has the value "Maximized", OnActivated gets called first time bevore OnLoad(). Can someone explain this benaviour? thanks Torsten Tag: RichTextBox Fields Tag: 77967

    - Delete allowed even when datagrid is set to readonly! I have a datagrid bound to a strongly typed dataset. The datagrid can be made readonly by either setting its ReadOnly property to True or by setting the dataset's DefaultView's AllowDelete, AllowEdit, and AllowNew properties to False. But in either case the datagrid still accepts a delete keypress (i.e. press the delete key on the keyboard) and while this doesn't actually delete the record it does set the dataset's HasChanges property to True thereby causing my code to incorrectly ask the user to save his changes. Can this problem be fixed? Tag: RichTextBox Fields Tag: 77965

The click event is kind put in a que. Now if there is a button or other control where that person clicked, the button / control click event is fired after my earlier procedure has finished. Here is how you can duplicate the thing. - Create a windowsform, put a button control on it, - Write a procedure onClick event of button Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button1.Click MessageBox.show("Test", "Test", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1, MessageBoxOptions.DefaultDesktopOnly) End Sub - Now Build and run the app - Click the button - {move the Messagebox out of the way, so you can see the button} - click on the button again - now click any button on the Messagebox - {Now here is the problem} you will see the message box again. {message box for second click} can some tell how disable this feature in my app. or work around. i have tried disabling the control and also form before displaying the messagebox but still the same problem. Can anybody help Thanks in advance mk Tag: RichTextBox Fields Tag: 77945

    - Control validation problem prevents me from tabbing out of a contr I am using simple databinding on a small form with only about 10 controls. My problem is that the _second_ time I open the form and edit a value, I am no longer able to tab or click out of the control that I just changed the value in. Here's what I mean: 1. Open the app 2. Open the Details form (form uses databound values for textboxes, code below) 3. Edit the value in the ItemName textbox 4. Click the OK button to close the form 5. Open the Details form a second time 6. Edit the value in the ItemName textbox Result --> I am now unable to tab out of the ItemName textbox, click OK or do anything but close the form. This appears to be a problem with validation, since I cannot click on any buttons with CausesValidation = true but I can click on buttons with CausesValidation = false. However, none of my controls on the form have an event handler for the Validating event. This happens consistently throughout my application, on both small forms and large forms. I must be doing something incorrectly. Can someone point it out to me? Here's some code: MyDataSet.MyRow row = // a valid row from a typed dataset Inside Form_Load: BindField(ItemName, "Text", row, "ItemName"); public static void BindField(Control control, string propertyName, object dataSource, string dataMember) { Binding binding = control.DataBindings[propertyName]; if (null != binding) control.DataBindings.Remove(binding); control.DataBindings.Add( propertyName, dataSource, dataMember); } -- ---- Doug Perkes Tag: RichTextBox Fields Tag: 77943

    - Annoying! Form Cannot Be Activated Eventually (.NET 1.1) This is so annoying that I have to see if it's happened to anyone else and see if I'm missing something well-known (I am not a WinForms expert). Frequently, my form loses the ability to become active. This happens when I'm debugging with VS.NET 2003 - I've been debugging for a while, so wouldn't know whether it happens outside of the debugger. It happened just now when I maximized the form. It maximized just fine, but changed appearance to look inactive, and in fact was inactive. Clicking on any part of the form doesn't change anything. Mousing over a top-level menu item highlights it, but clicking on it does nothing. Mousing over the Close, Minimize and Maximize buttons highlights them as well, but clicking does nothing. Right-clicking the notification icon shows the correct menu, and I can minimize, maximize and restore. None of those makes the form active. Clicking in the body of the form seems to make the form caption flash briefly, but nothing happens. Now, the one thing I'm doing that's a bit unusual is that I'm hosting several one of several user controls in a panel in the middle of the form. I _did_ have a problem with these. I had meant to remove and Dispose the old user control before adding the new one, but that didn't work: public static void ShowControl(Control control, Control container) { System.Collections.ArrayList disposeList = new System.Collections.ArrayList(); foreach (Control old in container.Controls) { disposeList.Add(old); } foreach (Control toDispose in disposeList) { container.Controls.Remove(toDispose); if (!toDispose.IsDisposed) { //toDispose.Dispose(); // This crashed. I forget the exception. } } control.Dock = DockStyle.Fill; control.Size = container.Size; container.Controls.Add(control); control.Show(); control.BringToFront(); } Maybe this is catching up with me. Any suggestions? Every time this happens I have to start over. The only way I can close the form is through "End Process" in Task Manager! ----- John Saunders Tag: RichTextBox Fields Tag: 77939

    - Draw table with GDI+ Is there a quick and easy way to draw a table on a winform? For my university assignment, we are asked to practice drawing with GDI+, so we are not allowed to use any built-in controls. The table has 5 columns and 2 rows and the first row is the heading. I guess I could use g.DrawRectangle() and g.DrawLine() repeatedly, but that's too cumbersome, plus I want to achieve something like DrawRow(1) to insert data to a cell. Any good ideas?

    - Passing large data between forms Hello, I have an application that simulates heat exchangers. There is a Edit form that allows to edit the parameters of the heat exchanger - 50-60 parameters. Currently Iam using 6 structures (each with 8-10 elements) that I pass between the main form and the edit form. These structures are also passed around in other forms and modules (for saving to file etc.). Is there a better way of doing this ? i.e. not using structures etc. Thank you. vikrantca Tag: RichTextBox Fields Tag: 77937

    - Impersonation and SQL Connections Hello all - I'm having a problem concerning Impersonation while connecting to SQL Server. I'm not sure if I'm posting this to the right newsgroups, so let me know if it belongs elsewhere, and please excuse the cross-post. I'm writing a Windows Forms application that makes direct calls to a SQL 2k database. This application requires a user to log in, and confirms their login and password with whatever they have in Active Directory. I had planned for the program to use the credentials of the user logged into the application (NOT Windows) when connecting to the SQL Server, but it seems I've encountered a slight pitfall. I've been reading that in this scenario, using simple Identity Impersonation, the SQL Server will attempt to connect as "NT AUTHORITY\ANONYMOUS LOGON" because of a limit to the impersonation context. I'm having trouble believing that this is true. I can impersonate users in ASP.NET just fine, and connect to databases using those credentials, but am unable to do the same through a desktop application? It doesn't make all that much sense, but then again, I'm somewhat of an amateur in this regard. So, that said, can anyone provide any examples or help to get this working? I'm happy to provide code samples, I just wasn't sure if it'd be necessary. Thanks! Clint Tag: RichTextBox Fields Tag: 77935

    - Handle form closing I have an MDI form containing child forms. I want to handle form closing to display a confirmation message when a form is closed or when the main form is closed. However, the Closing even of the child forms is raised before the Closing event of the MDI form when you close the MDI form. So, if I catch the Closing event of the child forms and display a message, then catch the Closing even of the main form, then I get 2 messages displayed.

    - Large Fonts not scaling correctly on tab control. I have a problem which I have been able to reproduce in a very simple project. I have a form with a single tabcontrol control with two tab pages. The tabcontrol's Anchor property is set to Top, Left, Bottom, Right (all 4 directions). On each tabpage, I have a DataGrid. Each DataGrid's Anchor property is also set to Top, Left, Bottom, Right. I developed this simple application with my System's DPI setting set to Normal Size (96) and everything worked perfectly. The problem came, however, when I changed my DPI setting to Large (120). The datagrid on the first tabpage (index 0) did not have the correct size (too large). On the second tabpage (and any others that were present in subsequent tests), everything was sized correctly. The same problem happens in reverse (developing in Large and moving to Normal). My workaround was to create an empty tabpage at the beginning of the set and remove it from the tabcontrol's TabPages collection during the form's load event handler. I could have also not used anchor and changed the control's width during the form's resize event. Any non-hack solution or explanation would be appreciated. Tag: RichTextBox Fields Tag: 77893

    - Datagrid Empty Set Here is one I am stuggling with: I have a project I'm developing in VB .NET. I have a datagrid in a window with two columns. The first column is readonly and the second column is not and initialized with Zero's. The values in column two must be numeric. How do I prevent the user from leaving an Empty set in the cell?

    - ComboBox woes I need help solving a couple of problems (and learning a couple of concepts) involving ComboBox columns in my DataGrid. The first problem involves my custom ComboBoxColumn class. I don't have experience making custom classes so I downloaded some code. From what I've read, it's pretty standard for adding a ComboBox column. It overrides the Edit, SetColumnValueAtRow, and GetColumnValueAtRow subroutines. It works great, but it doesn't allow the user to type in custom items in the combobox. Anything you type in just gets ignored. I want users to be able to add new items to the database through the comboboxes. I don't understand all of this code, though, so I'm not sure how to do this. The comboboxes are bound to datatables, so when the changes are committed I just need to add a new row with the new text to the datatable. Then when my "Update Database" button is clicked, the table changes will get sent to the database. It looks like maybe SetColumnValueatRow is the key subroutine? The second problem involves the relationship between my query form and my display form. My query form is a series of ListBoxes bound to certain DataTables in my DataSet. But before I fill the tables from the database, I add an item called "All" to the tables so that I can select all items in the listbox for query purposes. The problem is that the comboboxes in my datagrid are bound to the same tables, so I have to remove the "All" item before displaying the datagrid or else "All" will be displayed as a selectable item in the combobox. This works fine if you use the query form once, but if the user clicks the "Back" button on the display form I have to put the "All" item back into the tables for use in the query form. But inserting an item in a datatable that is already filled doesn't seem to be as trivial as adding a row to a blank table. Obviously I want "All" to be the first item in the list, so I can't just tack it on to the end. Right now I have to clear the tables and refill them, which is taking about 15 seconds. I guess one solution is to just make copies of the tables and put "All" at the first index in one of them and bind each listbox and combobox to different tables, but it seems there should be a more elegant solution. Is there a syntax for inserting a custom item in a datatable at index 0? Tag: RichTextBox Fields Tag: 77878

    - Distinguish Home key from NumPad Home key? Hi all, Does anyone know if it is possible to distinguish between a user pressing the dedicated Home key versus the Home key on the number pad (NumPad 7 with NumLock off)? I'm working in VB.NET on WinXP Pro. The standard KeyPress/Down/Up events return identical key codes. I've tried the API GetKeyboardState call and I've even tried keyboard hooks as described in http://www.developer.com/net/net/article.php/11087_2193301_1/ I'm able to accurately determine state of the NumLock key, but NumPad 7 with the NumLock off appears to generate the same key code as the dedicated Home key. Has anyone had any experience in this area? I've been looking at this issue for a while, so it's possible I'm overlooking something simple :) Thanks, Jim Tag: RichTextBox Fields Tag: 77865

    - How to manualy initiate the event? Hi, I would like to know if there in C# an equivalent to the VB.NET RaiseEvent statement. I would like to raise an event of a control in my code as if the user's action provoked it. Thanks, Haim. Tag: RichTextBox Fields Tag: 77848

    - Forms designer hangs when control added (combobox or listbox so far) hi. i've searched everywhere for an answer to this problem, and the closest thing i've found is a report from someone else with the same problem. using vb.net, ver 2003. this happened before installing the latest .net framework update and after. i have a simple windows forms app. a couple of forms, using textboxes, tabgroups, labels, and buttons...nothing complex. i try adding a combobox control to this form, and the IDE hangs indefinitely (need to end task it). the first time i had this problem was a couple of months ago with a larger, more complex application... i had created some custom controls that inherited from some of the base windows.forms controls, and was having all sorts of fun with the designer not being able to "get it", refusing to render forms, hanging if it did manage to open a form, and so on. the visual inheritance problem was easily fixed by simply building the project, though i still had to be careful what controls i selected on a form in design time in case it hung. since then i've tried to do as much "visual" stuff as possible in the code view, but i've encountered this again and can't get to the bottom of it. i've just run another vs.net process and attached the debugger to my hanging one. i've noticed that the hanging occurs when i move the mouse off the form (say, over to the properties dock) but having said that i've previously noticed that the hang happens after a small period of time, no matter what you do with the mouse. so yeah, i've got a nice bit of disassembled code that's stuck in a loop, details: Address: System.Windows.Forms.NativeWindow.Callback (^this is what's looping) it calls: System.Windows.Forms.Message.Create returns to NativeWindow.Callback, then calls: System.Windows.Forms.Design.ControlDesigner.ChildSubClass.WndProc which calls: System.Windows.Forms.Design.ControlDesigner.get_DesignerTarget System.Windows.Forms.Design.ControlDesigner.set_DesignerTarget does anyone have any ideas? any pointers in the right direction would help a lot!

    - howto put a Byte Stream directly in a picture-box? Hi, In my application I receive a Byte Stream (Dim bytFile() As Byte) which contains a jpeg-picture, which I want to display in a picturebox. I want to display it directly from the bytfile() without first writing it to a file and than reading it. Does anybody knows how to do this? I hae alreaddy a solution with writing it to a file, but the next time i want to do it I get an exception that the file is still in sue when I want to write to it. So to get aroudn this kind of problems I want something without file... My code with the file: Dim strPicLoc As String strPicLoc = "C:\test.jpeg" 'picture RetStatus = EIDlib1.GetPicture(MapColPicture, CertifCheck) Dim br As New BinaryWriter(File.OpenWrite(strPicLoc)) Dim bytFile() As Byte bytFile = MapColPicture.GetValue("Picture") br.Write(bytFile) br.Flush() br.Close() br = Nothing 'show the picture in the picturebox! picPicture.Image = Image.FromFile(strPicLoc) Thanks a lot in advance, Pieter Tag: RichTextBox Fields Tag: 77842

    - Tree control allowing multiple parents for a node (Graph) Hi, Does anyone know of a control that can display (and ideally allow users to manipulate) a graph structure (similar to a tree structure, but where a node can have more than one parent)? This would be most useful! Thanks, Mark. Tag: RichTextBox Fields Tag: 77841

    - Improved NumericUpDown control Hi all I am trying to implement an "improved" (silly users :-) NumericUpDown control. This control is meant to display floating-point values and the improvement consists in being able to mouse-select one digit of the FP value and when pushing the up/down arrow, increment this digit. The only solution I figured out so far (not implemented though) is the "hardcore" way, i.e. trap the events to check which digit is selected (yuck... variable size font ??). Does anybody can think of an alternate way to achieve this ? TIA a+ Nicolas Tag: RichTextBox Fields Tag: 77836

Hy,

Is there any way (other than implementing it all by myself) to have text
sections within a RichTextBox be only editable as whole sections? (namely,
the user won't be able to select parts of a section and would only be able to
delete the entire section)

Thanx
