    - When does the AutoScrollPosition value change? Hello! I have a panel with AutoScroll enabled. After Scrolling I read out the X and Y values from AutoScrollPosition but they are still 0. How come? I need to find out the position of the scrollbars so that I can correct the X and Y values I use in the MouseUp event to show a popup menu at the correction position. Thank you for helping. /David. Tag: Inherit TextBoxBase Tag: 66395

    - default directory c:\winnt\system32? Hello, I have a very simple C# WindowsForms app accessing a file. Framework 1.0 SP2. The filename is used without any path reference. On 99% of machines I tested, the file is correctly located in the applications startup directory. On one machine however, it looks for the file in c:\winnt\system32. I can of course reference the path by using Application.StartupPath, but I would like to know what is causing this, since the one machine is a production server... Any clues?

    - Anchor/dock property I have a forms application which has many controls such as buttons,labels,listviews,text boxes etc. If you set the window size to maximum size so that it would expand to the size of the screen the controls tend to move without any proposion. So then I used anchor and the dock property. I could get some or most of them to appear correctly, but say you have to list boxes in the middle of the screen one after the other vertically how could you use anchor or dock property.

    - Serializing/DeSerializing System.Windows.Forms.Cusrsor object looses the hotspot Hi All, We are trying to Serialize a System.Windows.Forms.Cursor object and Deserialize it. Before serializing the cursor behaves correctly but when we serialize and use a deserialized object, the hotspot (the cursor pointer) is not where it is expected to be.

    - Designtime turns to Runtime when copy-pasted... This is a really bad behavior of the design time, but I am not sure if it can be avoided in some way. Basically: I created a custom LicenseProvider that checks the context for the UsageMode (DesignTime or Runtime). Depending on that it uses a design time algorithm or a runtime one to get the license. However, if you select a control and then use copy + paste (either by keyboard or context menu) the pasted control has the context set to Runtime... This is really bad... Here's how to replicate: create a user control and a LicenseProvider. In the license provider's GetLicense method put a message box to display the context.UsageMode. Add the control to the toolbar, drag and drop it on the design surface. Then select it and press Ctrl+c and then Ctrl+v. You will see that the second control will show "Runtime"... Unfortunately I didn't find a way yet to go around this... Perhaps someone has an idea thanks iulia Tag: Inherit TextBoxBase Tag: 66377

    - Rich TextBox Text input I am trying to read text input from a rich text box control. For example if there are 10 rows of text in the text box and the user moves the cursor(or caret,by the way there is no mouse interaction)to a certain row and then say press Key "A" the text on that row should be extracted. Anybody know how to do this. Thanks in advance Tag: Inherit TextBoxBase Tag: 66373

    - custom design UI I am currently working on an application where we decided to have a customized look and feel (as opposed to the standard Windows UI). I took an approach using graphics to define windows borders and buttons, etc... but I'm not satisfied at all with the performance. Windows take a long time to display making this interface less than friendly. The graphics for the windows borders are placed on the form using PictureBox controls. Graphics are GIFs ranging from 1K to 5K with 90% of graphics between 1k and 2K. Am I taking the wrong approach? What would be a better way to go about this? Thanks a lot for your input Ben Tag: Inherit TextBoxBase Tag: 66370

    - Possibly strange behavior with ToolTip. I have a .NET application that seems to have a really strange bug. The following code represents a form that adds a control (in this case, a label) to a form every few seconds. The code is similar to the application I'm working on. As my application receives data, it will add or remove user controls which represents the data on the fly When I create the control I set its tool tip. When the control is added to the form, the form takes focus on the screen. This is a really annoying feature as I don't want the user to work with another application and have my application pop up in the foreground every time my application receives new data. The really strange part is that this behavior goes away when I remove the code to set the control's tool tip. Does anyone have any ideas why this is happening using System using System.Drawing using System.Collections using System.ComponentModel using System.Windows.Forms using System.Data namespace WindowsApplication /// <summary /// Summary description for Form1 /// </summary public class Form1 : System.Windows.Forms.For private Timer timer private int yOffset = 0 private int i = 1 private System.Windows.Forms.ToolTip toolTip1 private System.ComponentModel.IContainer components /// <summary /// Constructo /// </summary public Form1( InitializeComponent() StartTimer() /// <summary /// Clean up any resources being used /// </summary protected override void Dispose( bool disposing if( disposing if (components != null) components.Dispose() base.Dispose( disposing ) #region Windows Form Designer generated cod /// <summary /// Required method for Designer support - do not modif /// the contents of this method with the code editor /// </summary private void InitializeComponent( this.components = new System.ComponentModel.Container() this.toolTip1 = new System.Windows.Forms.ToolTip(this.components) // // Form // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13) this.ClientSize = new System.Drawing.Size(292, 273) this.Name = "Form1" this.Text = "Form1" #endregio /// <summary /// Start the timer to dynamically add components /// </summary private void StartTimer( timer = new Timer() timer.Interval = 5000 timer.Tick += new EventHandler(OnTick) timer.Start() /// <summary /// Called each time the timer's interval has passed /// </summary /// <param name="sender"></param /// <param name="args"></param private void OnTick(object sender, EventArgs args SuspendLayout() Label label = new Label() label.Text = "Label" + i label.Size = new Size(200, 15) label.Location = new Point(0, yOffset) Controls.Add(label) toolTip1.SetToolTip(label, "Label" + i) ResumeLayout() yOffset += label.Height i++ /// <summary /// The main entry point for the application /// </summary [STAThread static void Main() Application.Run(new Form1()) } Tag: Inherit TextBoxBase Tag: 66366

    - How can my application determine when the system is shutting down? I am currently developing a taskbar-icon based program which normally has no open windows. I understand that there is a Microsoft.Win32 event that is supposed to notify the application, but this event fails to fire when the computer is shut down. I have Windows XP. By not knowing when the computer is shutting down, my application stays in memeory when the computer tries to shut down, so all proccesess except the app close. To avoid this, you must manually close the program before shutting down the computer. I hope that I can find a way to make my program more user-friendly in this respect. I would apprectate any information on this subject. Tag: Inherit TextBoxBase Tag: 66364

    - Single Instance of App Per User I have been asked to make sure that a WinForm app can only have one instance and this would not be an issue if that was the only part. I could simply loop through the processes and see if the process name is already in the collection. However, the second part of the request was to make sure that if someone is running the app and someone else does the quick login or uses Terminal Services that they be able to run the app under their network ID. So I need to find a way to look at processes under a particular user or to compare the processes users. Anyone know how this could be done? TIA -Stanley Tag: Inherit TextBoxBase Tag: 66348

    - Changed dataset values mystery This, to me, screams 'Bug!!!!', but before I get into support calls to Microsoft type stuff, does anyone have any suggestions about how the following can happen.... VS 2003 using VB.Net. I have a Windows form that is used for displaying data from a dataview. The dataview sorts a dataset, and also filters it so that only records relating to the current user get shown. In the particular situation where I know I can recreate my problem, the dataview contains 4 records. There is a field called Nominee. For the record with the reference AG 11 (i.e. the key field), the nominee is NMS. So... DealDS1.Tables("Main").Rows.Find("AG 11").Item("Nominee")="NMS" I now want to import data into the dataset (...fields are set so that the data will also fall into the dataview as well....). I read the first line of data from a spreadsheet, add a new row onto DealDS1.Tables("Main"), set the values of the fields, and then add the datarow onto the dataset. Fine. No problem (normally). Again going back to the spreadsheet that I know makes it go wrong, this works up until the 6th row. Then this happens.... Read the 6th row of the spreadsheet. Add a new row onto the dataset.... newrow = DealDS1.Tables("Main").NewRow Set the values of the fields. newrow.Item("Blah")="Whatever" for various fields Stepping through this code I now look at the value of DealDS1.Tables("Main").Rows.Find("AG 11").Item("Nominee") and it's NMS Next line of code adds the row onto the dataset.... DealDS1.Tables("Main").Rows.Add(newrow) (the new row as a key value of AG 26) And after that line DealDS1.Tables("Main").Rows.Find("AG 11").Item("Nominee") is now NMA I have no code that I can see that is getting triggered by adding the new row. So that just can't possibly happen. Can it? Tag: Inherit TextBoxBase Tag: 66346

    - How to determine single click vs. double click? I have a windows forms application that needs to do one thing for a single click and another thing for a double click event. However, the forms click event gets fired whenever a double click event occurs and I don't want to perform the single click event plus the double click whenever the user double clicks on the form. What is the best (standard) way to handle this? IMHO it seems like there should be three Click events for a form: Click - Gets fired on first mouse down mouse up MouseDown Click MouseUp SingleClick - Gets fired after click if no double click MouseDown Click MouseUp SingleClick DoubleClick - Gets fired after second mouse down mouse up MouseDown Click MouseUp MouseDown DoubleClick MouseUp Am I missing something?

    - Question about DataTable and DataGrid Hi, - I have created a table that has 4 columns (type System.String) - called myDataTable. The table is created during the Form_Load function. - I have created a DataGrid, called dataGrid1. Now, to my problem: Each time my user clicks on the "search" button, a search is performed, the table is cleared with myDataTable.clear() and filled with the new data. Then I want to bind the DataGrid to the table, using dataGrid1.DataSource = myDataTable -- which contains the new results each time. But - I am getting an exception. Since I have tried to debug this, I am almost positive that the problem is related to the binding. Can someone offer help? or shed some light on how to bind the Grid to a table? Actually I would love to know if there is a way to fill the DataGrid control without messing around with tables or datasets... BTW - I am using C# Thanks Tag: Inherit TextBoxBase Tag: 66329

    - Tooltips on a PropertyValueUIItem I've successfully enabled PropertyValueUIItem use on a PropertyGrid by making a Container that implements IPropertyValueUIService, and then adding the PropertyGrid to it. As a result, you get nice tiny icons that sit on the property name, and you can double-click on them to invoke a handler. However, the MSDN documentation seems to think you can also associate a tooltip with the PropertyValueUIItem. I've done so, but no tooltip comes up. I've plowed through ILDASM on several .NET DLL's and don't see any fetching of the ToolTip property -- so question is: is this actually implemented? And if not, is there a suitable workaround? (Say like 10 lines of code that will automagically re-enable tooltips in property grids...) Cheers, Glen Low, Pixelglow Software www.pixelglow.com Tag: Inherit TextBoxBase Tag: 66313

    - DataGrid's CurrentRowIndex doesn't show new row's index. I've got a strongly typed dataset with three tables. Call them parent, child, and grandchild. There are relationships between parent and child, and between child and grandchild, using fields parentId and childId respectively. parentId and childId are autoincrement, with seed = 0 and step = -1. On a form I've got a DataGrid (with the most important fields) and some textboxes (with more details) at each level. That is: dgParent.DataSource = ds dgParent.DataMember = Parent dgChild.DataSource = ds dgChild.DataMember = Parent.Parent_Child dgGrandchild.DataSource = ds dgGrandchild.DataMember = Parent.Parent_Child.Child_Grandchild txtParentDetail.DataBindings.Add(New Binding("Text", ds, _ "Parent.ParentDetail")) txtChildDetail.DataBindings.Add(New Binding("Text", ds, _ "Parent.Parent_Child.ChildDetail")) txtGrandchildDetail.DataBindings.Add(New Binding("Text", ds, _ "Parent.Parent_Child.Child_Grandchild.GrandchildDetail")) Viewing data from the database, everything is cool. I can change existing data and update it fine. I can create new grandchildren. The problem arises when I click in the last (empty) row of the Child DataGrid, wanting to create a new Child of the current parent. I enter some data, tab to the next field, and the data I entered vanishes. Furthermore, the Child-level textboxes continue to display the data of the last Child record I was looking at (before I clicked into the last row of the Child DataSet). I expected them become blank, showing that data has not yet been entered for the new Child row. Thinking perhaps the Child DataGrid and Child textboxes had somehow got different CurrencyManagers. I took a look at this: BindingContext(dgChild.DataSource, dgChild.DataMember) Is _ txtChildDetail.DataBindings("Text").BindingManagerBase. But it was true, which I think is as it should be. Then I put some code into the dgChild's CurrentCellChanged event, to display the DataGrid's current row and the CurrencyManager's position in the status bar. MyStatBarPanel.Text = "DG: " & dgTktGrp.CurrentRowIndex.ToString & _ " CM: " & BindingContext(dgTktGrp.DataSource, _ dgTktGrp.DataMember).Position.ToString What I found here was that the DataGrid's CurrentRowIndex and the CurrencyManager's Position were always the same as each other, which is good. BUT, neither of them changed when I clicked into the last (empty) row of the DataGrid. Which doesn't seem right, does it? If anyone can explain either (a) what I might be doing wrong to cause this oddness or (b) why this behavior is perfectly natural and what is the proper way to add new records at the Child level, I will be very grateful.

    - Error '33' in the paint routine... This is one of those weird errors that probably nobody knows of, but I will try anyway, maybe somebody knows... I designed a datepicker as a drop-down control. When the control drops the floating form calendar is displayed. One can press the year and a numeric up-down appears where you can change the year. All controls are inherited and I override the WndProc and handle all mouse message so that no one of the controls gets focus, in this way the main form never looses focus when the control is dropped-down. All is fine except for the following situation: when the application starts the control is not focused. The control is then either clicked or tabbed to. If you click the year the numeric up down appears. Here is what happens: one of the buttons of the numeric up down generates an error in the WndProc on the WM_PAINT message. The error is the windows error #33: ERROR_LOCK_VIOLATION. What is extremely weird is: both buttons (up and down) are of the same exact type and they both created and dealt with in the same manner. Still only one has this strange behavior. Also, if one presses the tab key a few times and the focus goes away from the control and then returns to it... no error occurs... What can be the problem?? The floating form is a form with a custom control on it who owns the numeric up-down. The form is shown using the SetWindowPos api... If anybody has any idea, or suggestions? thank you, iulian Tag: Inherit TextBoxBase Tag: 66308

    - Version resource for C# Hi, Is there a way to add a traditional C++ style version resource to a C# Windows forms-based application? The version resource is what gets displayed on the Version tab when you bring up the property sheet for the .exe or .dll file in Windows Explorer. In the documentation I see a version resource editor for C++, but it looks like resources for C# and managed C++ are done differently. I do not need to read this resource from inside the code, it is just that this is our first .NET-based product and we have an internal standard that all released products need to have correct version information in all modules. This is so tech support can have the customer bring up property sheets in Explorer to figure out exactly which versions of everything the customer is running.

    - List tables and columns in designer I have a control that I am working on that interacts with a DataSet to display data. I want to be able to use the designer with this control in the same way as with the DataGrid control, where once a DataSet is associated with the control, I can then select tables and columns from the DataSet for displaying (assuming of course that the DataSet is stingly typed). Can anybody provide any pointers? So far I have only managed to associate the DataSet in the designer (well, that bits not exactly difficult is it!). Thanks. Tag: Inherit TextBoxBase Tag: 66292

    - Shuting Down XP from within a Windows Form Application Hi I'm fairly new to the .NET programming environment. I am writting an Windows Form application that needs to shutdown the PC that is running the application. What is the proper way to do this Please refer me to documentation that can explain how .NET applications can control the PC on which they are running One of the things I would like to do is limit the access to XP features, for example, not allowing the user to access Control Panel, once my application is started. Thanks in advance - Neil Shor Tag: Inherit TextBoxBase Tag: 66291

    - BeginInit() and EndInit() in Generated Code Region When I create a form using the DataForm Wizard (VS 2003), the following lines of code get generated near the top of the Windows Form Designer generated code region: CType(Me.objdsDataForm, System.ComponentModel.ISupportInitialize).BeginInit() CType(Me.grdtitles, System.ComponentModel.ISupportInitialize).BeginInit() The corresponding EndInit() statements get generated near the bottom of the region: CType(Me.objdsDataForm, System.ComponentModel.ISupportInitialize).EndInit() CType(Me.grdtitles, System.ComponentModel.ISupportInitialize).EndInit() Can someone explain to me what these statements do? Also, since the DataSet and DataGrid objects both implement the ISupportInitialize interface, why do those objects need to be converted to the interface type before the BeginInit and EndInit methods are called? Why not just call those methods directly on the DataSet and DataGrid objects? Thanks. -- Greg Dunn Tag: Inherit TextBoxBase Tag: 66278

How do I inherit from TextBoxBase? It does not have a public,protected or friend constructor and yet Microsoft appear to be able to use inherit in the TextBox and RichTextBox. The TextBox IL displayed in ILDASM shows a TextBoxBase::.ctor.

MSDN says that you should inherit from 'TextBox' or 'RichTextBox'
instead of inheriting from 'TextBoxBase'.
