    - 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: How to make a dialog that is assigned to an MDI child 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? Thanks very much. Alex Tag: How to make a dialog that is assigned to an MDI child Tag: 97255

    - 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: How to make a dialog that is assigned to an MDI child Tag: 97252

    - Problem while adding text to the last column in listview. Hi all, I have a listview control which has four columns like { Col1, Col2, Col3, Col4}. I add data in listview like this, dim lvitem as listviewItem lvItem = listvie1.Items.add("Text") lvItem.SubItems.add("SubH1") lvItem.SubItems.add("SubH2") lvItem.SubItems.add(" ") Now after getting execution of few functions I update the last entry in my listview control so for that I use. for cnt = 0 to listview1.Items.count - 1 listview1.Items(cnt).SubItems(3).Text = "SubH3" /// Giving exact problem Next The 2nd line is causing me runtime exception the description is, Run-time exception thrown : System.ArgumentOutOfRangeException - Specified argument was out of the range of valid values. 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: How to make a dialog that is assigned to an MDI child 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: How to make a dialog that is assigned to an MDI child 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: How to make a dialog that is assigned to an MDI child 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.

    - 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: How to make a dialog that is assigned to an MDI child Tag: 97209

    - StatusBar sizing grip does not work correctly on dual screen displ I created a simple Windows form application with the status bar. Because I use a dual screen display I noticed that there is a problem with the sizing grip when I drag the form to the second screen. The sizing grip does not work when the form is shown on the second screen. I looked at other applications to see if this is a generic problem, but the sizing grip in other applications (like Internet Explorer) behaves correctly. Is this a bug in .NET Framework?

    - Deployment Project - Custom Checkbox Form - Can't reference value! I created a setup project in VS.NET 2k5 and added an additional dialog to ask the user where they would like to place icons for my application. The options are Desktop and QuickLaunch Menu.

I have found other users complaining of the same thing, and I have followed the instructions given at: http://msdn2.microsoft.com/en-us/library/k3bb4tfd.aspx under the "To add the samples to the installer" section about 3/4 of the way down the page.

    - control change events altering other controls. I have occasions when a user changes the entry in one control the entry in another control is automatically changed.

    - 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: How to make a dialog that is assigned to an MDI child 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: How to make a dialog that is assigned to an MDI child Tag: 97191

    - maximized MDI Child position shifts Hi. I'm using VS2005, Framwork 2.0. I have an MDI app. The child forms are maximized within the parent. The child forms have the controlbox property set to false and the text property is empty. When my child form opens, the top 40 pixels or so get covered up by the parent. It seems that the child form is shifted up. So I changed my child form so that all controls are shifted 40 pixels down, leaving 40 pixels of empty space at the top. When I do this, the child form shows up correctly as the empty space gets covered up rather than my controls. But once and a while (I haven't found the pattern yet) the child form will shift back down that 40 pixels leaving me with blank space up top and covered controls down below. Has anyone else seen this behavior? I have noticed that if I put a value in for the text property of the child form, I don't have to shift my controls down 40 pixels and I don't get the random shifting. But the parent form takes this child text property and appends it to it's own text property in brackets. Mabye the answer is to put something in the child text property and somehow override how the parent writes it's text property? Can someone help me on how to do this? Thanks in advance.

If we merge many dll into one does it improve the performance. Our application takes long time to load, and we are doing nothing at startup. We are using "no touch deployment". Please suggest any way to load the application faster. Any help greatly appreciated. Dan Tag: How to make a dialog that is assigned to an MDI child Tag: 97155

    - Making a Winforms app behave like a Console app I am attempting to add a "console mode" to my Winforms app. My intention is that when I start the app with a special switch (for example "myapp.exe /batch") to does not launch a graphical UI but instead just displays console messages. My first guess was to simply change the Main method of the startup class to do something like this... if (batchMode) { Console.WriteLine("Now in batch mode"); ... } else { MainForm.Run(); // Launch graphical user interface } Unfortunately, it looks like my app does not behave like a real console mode app in either case. When I execute the app from the command line, the app returns immediately and text output by Console.Write() does not appear anywhere. Setting the app as a Console mode application does not give me what I want either. With this mode, a big black console output box appears even when in "GUI mode". Is there a way to build one executable that supports both modes and dynamically switches at runtime? Tag: How to make a dialog that is assigned to an MDI child Tag: 97151

    - Sync databound combobox to current bound record in form VS2005 I've been reading all the help I can on the topic (MSDN, other) but I can't make sense of this. Desired behavior; The user is to choose from the displayed list of the databound combobox and the coresponding 'Id' from the lookup table is to be inserted into the field of the new record. I have two simple tables. "tblPerson" is the data table. The lookup table is "lkpPersonType". The combobox dropdownstyle is "dropdownlist" to limit the user to the list. Here are the two tables "tblPerson" Id int IDENTITY (1, 1) NOT NULL , Name varchar(50), Address varchar(50), fkPersonTypeId smallint "lkpPersonType" pkPersonTypeId smallint IDENTITY (1, 1) NOT NULL , Type varchar(50) NOT NULL , The form has two binding sources "TblPersonBindingSource" for the data table and "lkpPersonTypeBindingSource" for the lookup table. The Display Member of the combobox is the "Type" field and the value member is "pkPersonTypeId" field. The Text property of the combobox is set to the "fkPersonTypeId" of the table "tblPerson". The next parts I am unsure of... I did not set the Selected Value (???) I set the Selected Item to the "Type" field of the lookup table lkpPersonType When I run the app the combobox populates. The data seems to display properly for the first record, but the combobox does not cycle through the values I know are assigned to it for the other records. In other words it is not properly bound. However there is a relationship between the two tables in the dataset, but the relationship is not specifically refered to in the form. Here is my code in the load event; \\ Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TblPersonTableAdapter.Fill(Me.DataSet1.tblPerson) Me.LkpPersonTypeTableAdapter.Fill(Me.DataSet1.lkpPersonType) Me.FkPersonTypeIdComboBox.DataSource = Me.lkpPersonTypeBindingSource Me.FkPersonTypeIdComboBox.DisplayMember = "Type" Me.FkPersonTypeIdComboBox.ValueMember = "pkPersonTypeId" 'Me.FkPersonTypeIdComboBox.SelectedValue = ??? 'Me.FkPersonTypeIdComboBox.SelectedItem = "Type" Me.FkPersonTypeIdComboBox.Text = "TblPersonBindingSource.fkPersonTypeId" End Sub // Please help me make some sense of this and get it working.

    - XP Visual Styles in 2005 I'm trying to set the application to use XP visual styles, but in the properties page I tried to set it and I get the following: Startup object must be a form when 'Enable application framework' is checked. I have a sub main starting up the application and in there it determines which portal the user is eligible to use. So how do I get around this issue with having a form being my startup? Thanks Tag: How to make a dialog that is assigned to an MDI child Tag: 97148

    - Form Gradient Background Is the code below the proper way to achieve a LinearGradient Background on a form? Private Sub MyForm_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles Me.Paint Dim oBrush As New LinearGradientBrush(Me.ClientRectangle, Color.AliceBlue, Color.CornflowerBlue, LinearGradientMode.Vertical) e.Graphics.FillRectangle(oBrush, Me.ClientRectangle) oBrush.Dispose() end sub The reason I ask is because it looks like the Paint event is fired one time for each control on the form.

    - How can I find BindingSource has some changed data. Hi, In my WinForms application, I have a set of controls that are bound to a BindingSource control. When the user closes the form, I need to ask him if he wants to save data. The problem is I cannot find anyway to check if the value of any textboxes is changed! Obviously checking DataSet.HasChange is not adequate. The reason is that the user might be in middle of adding or editing a record so the record has not been reflected to underlying dataset yet, but user accidentally clicks on form close button. Any help would be appreciated, Alan Tag: How to make a dialog that is assigned to an MDI child Tag: 97142

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
