    - Deleting from a table via a dataset positioning problem I'm getting very confused trying to make my "Delete" button work. All looked ok at first, with: Private Sub DeleteButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DeleteButton.Click Dim pos As Integer = GetPosition() If MsgBox("Delete record " + Str(pos) + " (" + StatusString(pos) + ")?", MsgBoxStyle.YesNo) = MsgBoxResult.Yes Then TextBox1.AppendText("Deleting " + Str(pos) + " (" + StatusString(pos) + ")" + Chr(13) + Chr(10)) DataSet11.Tables("table").Rows(pos).Delete() End If End Sub Function GetPosition() As Integer GetPosition = Me.BindingContext(DataSet11, "table").Position End Function Function StatusString(ByVal pos As Integer) As String Dim drsi As DataRowState = DataSet11.Tables("table").Rows(pos).RowState Dim drss As String = "" If (drsi And 1) <> 0 Then drss = drss + "Detached " If (drsi And 2) <> 0 Then drss = drss + "Unchanged " If (drsi And 4) <> 0 Then drss = drss + "Added " If (drsi And 8) <> 0 Then drss = drss + "Deleted " If (drsi And 16) <> 0 Then drss = drss + "Modified" StatusString = drss End Function The msgbox says "Delete record 0 (Unchanged)?", and after clicking Yes, the values in the textboxes, bound to various fields in "table", do change to show those in the second record (ie record 1). But when I click again on Delete, the msgbox now says "Delete record 0 (Deleted)?", and clicking Yes has no effect. Even worse, I've found that after getting to the last record with... Private Sub TopButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TopButton.Click Me.BindingContext(DataSet11, "table").Position = _ Me.BindingContext(DataSet11, "table").Position.MaxValue End Sub ..then back to the second-from-last with... Private Sub DownButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DownButton.Click Me.BindingContext(DataSet11, "table").Position -= 1 End Sub ..(second-from-last rec shows ok), then Delete, the msgbox says "Delete record 88 (Unchanged)?", which is good. But after deleting it, (and the display going back to show rec 0 again for some reason) and then going to the last record again and clicking Delete again, the msgbox says "Delete record 88 (Deleted)?"!! (I have a 'debug' text box which shows the statuses of the last few records ('rows', I should say), and that clearly shows record 88 as Deleted, and 89 as Unchanged.) Whew! Thanks, if anybody's read this far. I'm confused. I'm clearly not getting something.

    - Disabling maximise button affects maximised form size...? I've just noticed that if I set a form's window state to be maximized, and also disable the maximize button on the title bar, then the form will cover the task bar. If I enable the Maximize button, then the form does not cover the task bar. I assume this is 'by design'.... but I need a window that has no maximize button (so the user cannot 'de-maximize it) but also I don't want it to cover the task bar. Is this possible through some other nefarious means? Cheers Ant Tag: Turn off blue bar at top of DataGrid Tag: 85081

    - Activate issue: not activated or active window on load I have a MDI application, but that isn't important, and why I posted it here instead of the MDI forum. I have class "App Loader" that contains Main. It loads a splash screen that shows up before the main window, and it runs on a background thread. It shows up while the app is loading. Once the app has loaded all the required resources, the main form is shown and activated. On Win 2003 and Win2K, the "app" flashes in the taskbar, but doesn't show up as the active window in the foreground. If you run it by clicking the EXE from within Windows Explorer, after it loads, Explorer is still the active window. I tried: //make this puppy come to front and activated Application.DoEvents(); this.TopMost = true; this.TopMost = false; this.BringToFront(); this.Activate(); This did improve the behaviour on XP, but not Win2K and Win2003.

    - What's wrong with DataView I have such sentence in my program: {... ... DataView dataView = new DataView(dataSet.Tables[0]); Console.Writeline(dataView.Count.toString());} And this module runs very frequently. There are ten records in the Tables[0] . But in one of PC with XP SP2, we can only get one record from dataView. That means dataView.Count.toString() is 1. Why? Tag: Turn off blue bar at top of DataGrid Tag: 85072

    - Debug makes Windows freezing? I used Visual Studio 2003/Windows XP SP1 to create a window application. At the form, I put a button and run debug. I put some break point on the Load event of form and it works fine. I also put a break point at click button event and click the button, but I never get the break point at the click button event. The Windows system seems freezing. I can not call other program. I can not use ALT-CTRL-DEL keys to restart the computer. But the Task Manager, which I started before debug, still displays the system parameters. The CPU usage is only 2 or 3 percent. The Mem Usage seems to be normal, too. I reinstalled the Visual Studio and I still got the problem. Could some one help me to solve the problem? Thanks - George Tag: Turn off blue bar at top of DataGrid Tag: 85070

    - Databinding Combobox to ArrayList (again: argh!) An ArrayList contains Person objects with Properties Name, Age, Phone. A Windows Form displays - TextBoxes for these properties as well as - a ComboBox for the Name and - VCR Buttons First/Previous/Next/Last. DataBinding should display the correct information in the textboxes no matter if navigation happens through the VCR buttons or the combobox. The combobox should always contain the same information as the txtName textbox. I tried several combinations of defining the databinding. No matter what combination of the following lines I used, I get errors from "stack overflow" to metadata/type info displayed in the combobox. txtName.DataBindings.Add("Text", myPersons, "Name") txtAge.DataBindings.Add("Text", myPersons, "Age") txtPhone.DataBindings.Add("Text", myPersons, "Phone") cboName.DataBindings.Add("Text", myPersons, "Name") cboName.DataSource = myPersons cboName.DisplayMember = "Name" cboName.ValueMember = "Name" 1) What is wrong? 2) How does the code need to be changed if objects should be added and deleted from the arraylist by additional buttons? thank you, herbert Tag: Turn off blue bar at top of DataGrid Tag: 85065

    - Can't access digital camera to copy from in code I am trying to copy pictures from a digital camera in code. When I use the FolderBrowserDialog, it won't let me select the camera as the folder. I have gotten around this by using Shell32.BrowseForFolder. I am then also able to get the names of the files. However, the path is a pidl (i believe). So I am unable to utilize .Net IO classes to manipulate the files. This is windows form that ultimately will allow the user to browse for a camera, pick a client, then ftp pictures to the server for later processing.

    - Datagrid exception I have a .NET windows forms application with one form displaying data. I have a tree view on the left side and the datagrid on the right side. Tree view allows the user to select verious items and based on that selection the datagrid is bound to the appropriate datasource and table from the database. This works well. The problem comes when I resize my form and the grid portion is not visible or just barely visible. Now when I perform the same operations by selecting various items in the tree I get an exception System.ArgumentException with Message : '0' is not a valid value for 'value'. 'value' should be between 'minimum' and 'maximum'. Source : System.Windows.Forms. This happens when I call SetDataBinding method. When I again resize the form so that the grid is more visible this problem goes away. I have also seen a bizzare display with red cross over the entire grid area when I resize the grid again. Is this a known issue in the datagrid ? Can somebody help me ? Thanks Tag: Turn off blue bar at top of DataGrid Tag: 85050

    - PropertyGrid - TypeConverter (DropDown) - Internet Explorer hosting problem Hi, I have created a Windows UserControl. This Control hosts a PropertyGrid and a Button control. The UserControl project also includes a class called "TestClass" and a custom TypeConvertor class called "DDConv". When the user clicks on the Button control, the application assigns an instance of "TestClass" to the PropertyGrid. The "TestClass" has a property called "CustProp" and it has an TypeConverter attribute assigned to the "CustProp" property. The TypeConvertor points to the "DDConv" class. The PropertyGrid in the UserControl displays a DropDown against the "CustProp" property when the UserControl is hosted in a windows application. When the UserControl is hosted in Internet Explorer, the PropertyGrid does NOT SHOW any DropDown for the "CustProp" property. NOTE: I test the UserControl in Internet Explorer from a virtual directory on my machine. I have set "FullTrust" for the "LocalIntranet_Zone" on my machine. I want the PropertyGrid to display the DropDown in Internet Explorer - can someone help me in figuring out how to acheive the same?

So I simply overloaded the constructor to accept the parameter...that easy enough, however the function that opens the form checks first to see if it's already open and if so just sets focus to that window.

    - How to embed a form in a form? This is what I would like to do: - The splitter window splitting the view to a tree view on the left and entry dialog on the right. The tree view and splitter are easy and it's already done. - It is easy to make a fixed form on the right pane, dock it and enjoy it working. However, I would like the form on the right pane to be dynamic, i.e., depending on a context of the tree view to display different controls and being managed by a different form derived class. In MFC I could accomplish this with child dialogs embedded in a parent dialog and depending on the tree context flipping the child dialogs visible/invisible. I can do the same in .NET by using panels with embedded controls, however, this way everything must be done in the runtime and I lose advantage of designing a forms in a design time and taking advantage of .NET studio wizards. If I could find a way to embed a child form in a parent form, then it would solve my problem. Is it possible? Thanks Tag: Turn off blue bar at top of DataGrid Tag: 85012

    - Editing a form in VisualStudio Using Visual C# .NET. I have successfully created my own Windows forms from scratch and been able to view and edit both the code and the designer (i.e. right click on the .cs file in the Solution Explorer pane and select View Code or View Designer.) I'm also modifying existing code, and have also successfully edited existing classes using View Code and View Designer. However, in one particular project there is a folder in which I cannot View Designer for the form class - the only option is View Code. Also, the icon shown is different from the usually forms classes - it's not the gray "control-looking" icon, but the green/white "text-looking" option. Both a .cs and a .resx file exist for form classes in question. This is code I got out of a library and my colleague is able to View Designer on these classes just fine. Any idea what's wrong?

    - TabControl and Data binding I've read elsewhere that databound controls on a tab are not actually bound to the datasource until the tab is made visible. I have an IsDirty flag that gets set in the TextChanged, CheckedChanged, etc, events on each of the controls and I'm setting up these event handlers in the form's load event. How can I avoid these events getting called whenever I change from one page to another? Or better yet, is there another event I could use to set the IsDirty flag? I tried the RowChanged event on the underlying DataTable but it wasn't firing. Tag: Turn off blue bar at top of DataGrid Tag: 84985

    - Need help in Data grid Hi I am developing a windows application. This contains a Data grid which will populate data from a data table in a Dataset. The application will do some calculation and store the result in the Data table. After the calculation, the result stored in the data table will display in the data grid. When number of rows need to populate in the data table after calculation is around 16000, application will take around 30 seconds to do the whole work. Because of this Data grid population from data table will also take 30 seconds or more. During these 30+ seconds, form will be blank and user cannot do any activity. I like to know, Is there any way to display the calculated rows part by part to the data grid from data table. (Like Buffer.Flush in Asp.net, to display part of the out put to the user). If I am able to display 1000 rows after calculation from data table to the data grid, the user no need to wait for whole calculation to be completed for the out put Give me some reply on this. Thanks in Advance. Umesh Tag: Turn off blue bar at top of DataGrid Tag: 84968

It doesn't wait for user interaction and just returns DialogResult.No . //This doesn't work properly DialogResult res = MessageBox.Show("Some description.", "Some Error"); //This works just fine DialogResult res = MessageBox.Show("Some description.", "Some Failure"); Can anyone else reproduce this behavior.

    - SendKeys doesn't send I'm writing an app that sends keystrokes to another app using SendKeys.SendWait(). On some computers some of the time, the call to SendWait() doesn't work. After it's called, the receiving application is sitting there focused and ready to receive the keystrokes (if I press keys, they work) but the keys never come and the sending app blocks infinitely. Like I said it's only on some computers and even on those computers it's only every now and again. There isn't any difference between the computers that it works on and those it doesn't that I can think of. Does anyone now why this is happening?

    - Building a Word 2003 Document with XML I have an old product that generates a Word document using Word Automation (tables, pictures, etc). The execution speed is quite slow and I'm finally at the point where I can tell my customers that they HAVE to have Office 2003. That brings me to the potential of building a Word document using the Word XML document schema. Has anyone done that - is this possible?

    - Control Data Source Assignment Best Practice I notice that if I assign a data source to a control in VS and necessarily call Fill after the assigment has happened, the form will load very slowly. If I hand-assign the data source after calling Fill, much faster. I assume this is because the control is firing off some event on a per row basis every time a row gets loaded into the dataset. But whatever the reason, what's the best practice here? Using the designer seems like a waste of time if there is such a high performance price. Is there a workaround for this? Thanks!

    - DataGrid adds blank row in typed DataSet I have encountered a strange behavior with the WinForms DataGrid which can be reproduced as follows: 1. Create a new Windows Application 2. Set Form1.IsMdiContainer = True 3. Add a new DataSet named DataSet1 4. Add an new element named Table1 to DataSet1 5. Add two columns named "ID" and "Name" to Table1 in DataSet1 6. Add a new Windows Form named Form2 7. Add a Datagrid to Form2 named DataGrid1 8. Add a DataSet of type DataSet1 to Form2 9. Set the DataGrid1.DataSource = DataSet1 10. Set DataGrid1.DataMember = "Table1" 11. Add the following code in Form1 Load event: Dim f As New Form2 f.MdiParent = Me f.Show() Run the application. Form2 shows up with 2 rows in DataGrid1. One blank row (containing (null) in both columns) and the AddNew row (the one with an asterisk). Where did the first row come from? It has somehow been added to Table1 in DataSet1. If I change the code to not include "f.MdiParent = Me" there is no blank row added, just the AddNew (asterisk) row is shown. Could someone please explain why the blank row is added when Form2 is a MDI child? Tag: Turn off blue bar at top of DataGrid Tag: 84926
