    - causes validation problem Hi, I have two buttons and a text box on my form amongst other things. The textbox is set to validate to see if there is no text in the box. The two buttons are set "causesValidate = false" . One of the buttons is in a group box. The other is on the form. The button on the form doesn't respond to the validating event as would be expected, however the button set in the groupbox continues to call the validating event despite it being set to false. Is this normal? Does the group box change something? If so, what should I do to stop the button in the group box from responding to the validating event? Any suggestions will be gratefully appreciated. Ant Tag: Datagridview Strange behaviour Tag: 97285

    - how to make an image draggable? I try to implement Drag & Drop in my application. It works rather well except I'm not able to drag in other application like, say, word. I tryed to look at what IE does and when I drag animage from IE it has the follwoing formats: [0]: "UntrustedDragDrop" [1]: "FileDrop" [2]: "FileNameW" [3]: "FileName" [4]: "DeviceIndependentBitmap" [5]: "HTML Format" In my code I created my 'drag value' as follow: byte[] imageData = ....; Bitmap bmp = new Bimtap(new MemoryStream(imageData)); DataObject dao = new DataObject(); dao.SetData(DataFormats.Bitmap, bmp); dao.SetData("DeviceIndependentBitmap", imageData); But that doesn't work.... Beside when I drag from IE the form DeviceIndependantBitmap is a stream, whereas with my code I generetae either a byte[] or a proxy what could I do? I would like to drag image from my application without having to save them to a file.... Tag: Datagridview Strange behaviour Tag: 97279

    - Inheriting a from with a special constructor Hi, I created a base form, what holds several graphical elements (text boxes, etc). This form has only one constructor, what expects one integer parameter. Call this BaseForm It's constructor looks like: public BaseForm(int Param1) { InitializeComponent(); } Now I inherit a second form from this one (Call this InheritedForm), and I found out, that I have to define the constructor as follows: public InheritedForm(int Param1):base (Param1) { InitializeComponent(); } Now, my problem is, that in the designer the form can not be shown, since there is an error: Construcotr on type 'WindowsApplication1.BaseForm' not found. Why? I defined the constructor! Moreover, if I create a second "default" conrtuctor: public BaseForm() { InitializeComponent(); } is not helping at all. How can I see in the designer the InheritedForm? How can I add more visual components on it? What did I wrong? Thanks: Peter Tag: Datagridview Strange behaviour Tag: 97264

    - How to make a dialog that is assigned to an MDI child I have an MDI application, and I'd like to create a dialog box that appears for an MDI child form, but does not restrict the user from switching to other forms in the application. The MDI form in question is a sales order with an inventory list that pops up as a dialog box. But if the sales person takes a call from a customer and has to check the status of another sales order, I don't want them to have to close down the dialog box to do so because they may have filtered the inventory list down, but not identified the product yet. Any help would be appreciated. Thanks, Trevor_B Tag: Datagridview Strange behaviour Tag: 97262

    - Databinding ComboBox with NULL values VS.NET 2003 I have a Windows Form application, with a form that has various controls, all of which are bound to a custom business object: Class Employee Private _employeename As String Public Property EmployeeName() As String Get Return _employeename End Get Set(ByVal Value As String) _employeename = Value End Set End Property Private _positionid As String Public Property PositionID() As String Get Return _positionid End Get Set(ByVal Value As String) _positionid = Value End Set End Property End Class SIDENOTE: Yup, I'm stuck with the PositionID being a string instead of the more sensible integer because of the existing database schema. My question revolves around the fact that the PositionID can be NULL, and the user needs to be able to set it to NULL as well. On my form, the PostionID is selectable by the user with a ComboBox. Here is how the ComboBox's DataSource is setup: Dim positions As DataTable = BuildDataTable() ComboBox1.DisplayMember = "PositionType" ComboBox1.ValueMember = "PositionID" ComboBox1.DataSource = positions The ComboBox is bound to the Employee object as follows (like the other controls on the form): ComboBox1.DataBindings.Add("SelectedValue", emp, "PositionID") The ComboBox's DropDownStyle is set to DropDown. I would like for the user to be able to simply delete the ComboBox's text and have an empty string ("") be propagated back Employee business object. The only way I have found to do this is the following 2-part process: 1) add an extra row with "" as its value to the DataTable that is the ComboBox's DataSource: dt.Rows.Add(New Object() {"", ""}) 2) add the following code to the ComboBox's KeyUp event handler: If (ComboBox1.Text = "") Then ComboBox1.SelectedIndex = ComboBox1.FindStringExact("") End If I would like to eliminate the part where i have to add a blank row to the DataTable, is there a way to do this? Please let me know if I need to provide more information. Thanks! David McClelland Tag: Datagridview Strange behaviour Tag: 97257

    - Measurement Unit problem with Printing. Hi, I have a problem where documents sent to the print spooler with a custom page size are ignoring the regional settings for the Measurement Unit. I have my Regional Settings set to "English (United States)" and confirmed that the Measurement Unit is "U.S". When I print my 4"w x 2"h label (using a custom paper size I set in my code as 400w x 200h (tenths of an inch)), it converts to tenths of a millimeter, resulting in a page size of 1.47"w x 0.79"h. I have tried checking the System.Globalization.RegionInfo.IsMetric in my code, and it returns False, as expected. Anyone have any idea why this is happening, and how I can correct the problem?

    - Capturing data from a separate application window? Hi all, I have found that I need to be able to write a windows application that is capable of attaching to an independent windows application (one I haven't written), and gather information. For example, this application gathers a bunch of data from disparate sources, and updates a log file every 10 minutes. However, the data is rendered to a textbox (or at least it looks like a textbox) in the application in real-time. So, I want to be able to attach to this window and get this data in real-time as well, so that I don't have to wait 10 minutes for this logs to update. Does that make sense? That said, I have no idea where to begin. I've found some applications that seem capable of doing this, but I don't know how it is they are doing it. If anyone has any information that they would be willing to share, to get me started and headed in the right direction, I would really appreciate it. Thanks! Wade P.S. I am using both VS 2005 and VS 2003 and VB.NET and C# -- any solution in any flavor is appreciated! Tag: Datagridview Strange behaviour Tag: 97252

Parameter name: '3' is not a valid value for 'index'. Initially it worked fine when I run my application 2-3 times but now it is crashing continuously. I have tried with the same functionality in the other application but that application is working fine. I am not able to figure out what is the exact reason behind this failure. I there any known bug with the listview about this issue I have also deleted the previous listview and added a new one but nothing is working fine for me. What could be the reason .

    - get value from combo box Gday, Am relatively new to dotnet so excuse me if this seems rather simple. I am trying to get the value of a bound combo box that has been set when the form is opened, and use this for another control. I am having trouble doing this for some reason. Here is what I am trying to do: Decimal var1 = (Decimal)cboMyComboBox.SelectedValue; This appears to return a datarow? Do I need to create a datarow object then access the value I need that way, or can I just access the selected item similar to what I am doing above? Also, the combo box has an id field (value member) and a display field (display member). Thanks, Peter Tag: Datagridview Strange behaviour Tag: 97231

    - Databind column to property on another referenced object... How do I databind a DataGridView column to a property on another referenced object? That is, I want to bind to "Parent.Name" where Parent is a property that references another object. I know this can be done when databinding TextBoxes. Surely it can also be done with grid columns. The following example should illustrate my problem: using System.Windows.Forms; namespace MyTest { class MyTestForm : Form { public MyTestForm() { DataGridView grid = new DataGridView(); DataGridViewColumn col = new DataGridViewTextBoxColumn(); col.HeaderText = "Parent.Name"; col.DataPropertyName = "Parent.Name"; grid.Columns.Add(col); col = new DataGridViewTextBoxColumn(); col.HeaderText = "Name"; col.DataPropertyName = "Name"; grid.Columns.Add(col); grid.DataSource = new BindingSource(new Child[] { new Child(new Parent("dad"), "son") }, null); this.Controls.Add(grid); } } class Parent { private string _Name; public Parent(string Name) { _Name = Name; } public string Name { get { return _Name; } set { _Name = value; } } } class Child { private Parent _Parent; private string _Name; public Child(Parent Parent, string Name) { _Parent = Parent; _Name = Name; } public Parent Parent { get { return _Parent; } } public string Name { get { return _Name; } set { _Name = value; } } } } Nathan Tag: Datagridview Strange behaviour Tag: 97230

    - ClickOnce publishing without uploading dotnetfx.exe Hi, I'm using ClickOnce to publish my application (MyApp.exe) to a web server. The application relies on a seperate application (CommonControls.msi), whose only purpose is to install a few third party components into the GAC. This application only has to run once on the user's machine. I created the product.xml and package.xml files, and this CommonControls.msi correctly appears in the Prerequisites box when I'm getting ready to publish MyApp.exe. Since I want CommonControls.msi to be hosted on my web server, I select the second download option (Download prerequisites from the same location as my application). Note that at this point both .Net Frameword 2.0 and CommonControls.msi are selected. I now publish MyApp.exe - everything works exactly as expected. The files dotnetfx.exe and commoncontrols.msi are uploaded to my hosting web server. However, now every time that I publish MyApp.exe, both these files continue to be uploaded. This means that instead of a 1.5mb upload, I'm making a 25mb upload each time. My question is - how do I tell ClickOnce to upload the prerequisites manually (i.e. should I ever change CommonControls.msi), yet inform the client program (MyApp.exe) to download the prerequisites from the same location as the application? Many thanks in advance for any thoughts on this. Regards Jeremy Holt Tag: Datagridview Strange behaviour Tag: 97224

    - Taskbar title different from window form text? I have an application that is currently running without the default titlebar, because the client needs the ability to create their own custom titlebar. The only way we have found to accomplish this is to remove the 'Text' from our main form, and also have no control buttons enabled whatsoever. This is all fine and good, they get the standard windows border that they like, with no titlebar. The problem comes when the application is displayed in the Taskbar. Since we removed the text property from the main form, the entry in the taskbar is blank. Does anyone know any way to set that text in the Taskbar to something other than what is in your form title? I have looked for API calls etc, but have come up blank. The other alternative is to hide the titlebar while still setting the text property for the form. If I set the FormBorderStyle = 'None', it does just that, but then we lose the standard border which the client claims is not acceptable. Thanks, Ryan Tag: Datagridview Strange behaviour Tag: 97221

    - RichTextBox question I've been messing about with the richtextbox control so that I can select multiple different fonts and change their styles, sizes etc together. But if I test the performance this by filling the box full of characters there is a noticeable lag while the update happens. To do this I'm using the following code: int selectionStart = rtbBody.SelectionStart; int selectionLength = rtbBody.SelectionLength; int selectionEnd = selectionStart + selectionLength; for (int x = selectionStart; x < selectionEnd; ++x) { rtbBody.Select(x, 1);// Selects one character at a time //Do code for checking/changing font styles, type size etc } It works perfectly apart from this delay. I've used unmanaged code to stop the rtb updating while this is happening and it helps a bit. Would it be more efficient if I manipulated the rtf directly in a string builder and then placed it back into the richtextbox? Looking at word, literally thousands of characters can be changed style, font etc instantly. Does anyone know how they go about doing this? Any help would be appreciated.

    - ResizeBegin & Change Size Programmatically Here is what I would like to do. The app's main form is a MdiContainer containing forms. When the user changes the size of the container the child forms are resized, too. I need to catch the beginning and end of the resizing of the child form. How can this be done. This is what is done currently. The container overrides OnResize. In this function the children's position and size is continuously adjusted as the user keeps on resizing the container. In the child forms I have overriden ResizeBegin and ResizeEnd. Unfortunately, they are not being called as they only react to manual resizing and not to programmatically changed sizes (like SizeChanged vs Resize). Are there any events like ResizeBegin and ResizeEnd that also respond when the resizing is done programmatically? If not what is the best solution to achieve this besides the main form telling the children that resizing begins/ends? Thanks Tag: Datagridview Strange behaviour Tag: 97209

    - ClickOnce, MSBuild and multiple servers. We're currently getting ready to deploy an application using ClickOnce. We'll be placing the deployment on two servers. Because the app.config files will need to point to different servers, we're using the revision number to indicate which server it came from. Currently, this means manually changing the version in the IDE and then publishing to each server. Is there any way to automate this using MSBuild? After looking around it appears MSbuild might be able to generate the files for publishing, but they would then need to be copied to the publish site, is this correct? Can you specify the version number in the build? -- Neil Tag: Datagridview Strange behaviour Tag: 97193

    - backgroundworker Question We have been using multi-threading in our application in 2003 with good results. When we migrated to 2005 our old code blew up, so we rewrote our code using the backgroundworker. It seemed to easy to be true. When we run our application now it seems that the screens are running synchronously and not Async. We usually have 3 to 4 backgroundworkers going at the same time inside the activated event for the form. See the code below to show how we are using the worker: Private QueueWorker As New BackgroundWorker Delegate Sub QueueDelegate() Private Sub LoadInitialQueue(ByVal sender As Object, ByVal e As DoWorkEventArgs) Try Dim ReturnAsync As IAsyncResult = BeginInvoke(New QueueDelegate(AddressOf SetupQueue)) EndInvoke(ReturnAsync) Catch exp As Exception MessageBox.Show(exp.Message.ToString) End Try End Sub Public Sub SetupQueue() Try QueueFlex.Redraw = False dsNotifications.Clear() dsNotifications.Reset() Dim parm() As Object = {Main.oProperties.UsersBankLoanTeamID, 0} DBCalls.AccessDataLayer.FillDataset("SelUserNotifications", Main.oProperties.ConnectionString, dsNotifications, New String() {"queue"}, parm) QueueFlex.DataSource = dsNotifications.Tables("queue") FormatQueue() QueueFlex.Redraw = True Catch exp As Exception MessageBox.Show(exp.Message.ToString) End Try End Sub Do we have to use BeginInvoke & EndInvoke with this new component because that seems like the bottleneck. If we do still need to use them what can I do differently that would make the UI more responsive. It just seems that we lost the UI responsiveness when we moved over to the backgroundworker. it looks like it gets the data from the sql server async but it doesn't populate the controls async so it looks sync. I don't know any help would be appreciated. Tag: Datagridview Strange behaviour Tag: 97191

    - Click Event on MenuItem with subitems Hi group, I have a MenuItem with some subitems.

MenuItem submenuImages = new MenuItem("Image", new EventHandler(this.menuItem_Image)); or submenuImages.Click += new EventHandler(menuItem_Image); But this EventHandler is never accessed. Why?

    - Resetting Combo to original state Hello, I'm using a combo box and some text boxes on an input form. When the user submits the input, all the textboxes should be cleared & the combo box reset to the way it was originally displayed (order desc.) How do I 'refresh' to combo box to display as it did? It is bound to a dataset via DisplayMember & ValueMember so it was not filled programmatically. How do I do this programmatically? (or not?) Thanks in advance for any clues.

    - Richtextbox control question Is there anyway to create similar behaviour to BeginUpdate and EndUpdate in a richtextbox control? I've seen a few work arounds on the net but they use unmanaged code. Any help would be appreciated, Chris Tag: Datagridview Strange behaviour Tag: 97165

    - Form Loading Issue - VS.NET 2003 Hello, I have a dialog in my VB.NET application that has some controls for configuration and an "Apply" button. The design calls for the Apply button to be enabled only after the user has made changes to the settings. To do this the change events for each control are used and the Apply button enabled when any control raises a change event. The problem is that when the form loads and default values are output the controls (correctly) fire change events. Is there a mechanism to get around this, so that only user changes enable the Apply button? Thanks, Sid. Tag: Datagridview Strange behaviour Tag: 97163

    - DataGridView automatically selects first row I'm setting the datasource of a DataGridView to a datatable. This loads the grid correctly but it automatically selects the first row in the grid, triggering the SelectionChanged event. Is there a way to stop the grid from automatically selecting the first row? Thanks. Tag: Datagridview Strange behaviour Tag: 97161

I've added a new field in the dataset binded to the datagridview, but I'm
not able inserting this field on my existing datagridview. I tried with
refresh options but the add column doesn't recognize the new field
