    - .manifest files, .config files, and UNC paths I've written a test program that shows that .manifest files and .config files won't work together when the app is run from a UNC path. Has anyone fixed this problem? To recreate the problem: 1. create an app named UNCTest with 1 button and 1 label on it. Add the following code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label1.Text = ConfigurationSettings.AppSettings("AttachRoot") & "xyz" End Sub 2. Add the following UNCTest.exe.manifest file to the project. <?xml version="1.0" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" processorArchitecture="X86" name="Microsoft.Winweb.UNCTest" type="win32" /> <description>.NET control deployment tool</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> </assembly> 3. Add the following app.config file to the project: <?xml version="1.0" ?> <configuration> <appSettings> <add key="AttachRoot" value="\\test\test\test\test\" /> </appSettings> </configuration> 4. compile the application and put it out on the network. Make sure to manually copy the .manifest file - it doesn't automatically move the bin folder like the .config file does. 5. map a drive to the network share where you put the exe and run the program. No problems when you click the button - you should get \\test\test\test\test\xyz in the label 6. run the program from a UNC (\\server\folder\UNCTest.exe). You should get a different result - just xyz (it's not reading the value from the .config file correctly). I've seen several Usenet messages about removing encoding from the .config and/or .manifest files - I've tried this and it doesn't work (note the two files above don't have encoding attributes). I can't use Application.EnableVisualStyles, either, b/c this blows up my app (even if I use Application.DoEvents right after). So, is there any OTHER workaround so I can enable XP styles, AND use a config file, AND run my app from a UNC path? matt tag Tag: Set Position of Window for Application When Launching from VB.NET Tag: 75879

    - DataGrid - row background colors - re-paint issues For my DataGrid application, what I need to do was display certain rows in one background color and certain rows in another based on changes in one column. I extended the DataGridTextBoxColumn class - essentially creating my own custom DataGridColoredTextBoxColumn class. Inside of that class I was able to override the Paint method: protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight) { and through some other method calls, am indeed able to color the backgrounds of my rows the way I want. The problems start happening when I scroll up and down or left and right. The repaint is horrific - leaving remnants of other cells where new cells just appeared due to scrolling and the colors get all out of whack )-: Does anyone have any ideas how to avoid this crappy repaint issue?? I've tried blocking the base.paint from getting called once the grid has been painted to my satisfaction, but this leaves me looking at nothing. Need help - thanks in advance!!

    - Sql Adapter in windows forms application vs webservice I am somewhat new to .NET and am working on a windows forms application in C#. My application will be accessing a database on a different machine than the windows application. About 10 instances of the windows forms application will be accessing the database at any given time. No other application needs to use the data. From a performance standpoint, is it better to have the windows forms application access the database with sqlAdapters right in the application, or is it better to use a webservice to return a dataset?

When I selected an Item, and afterwards I press "Delete" there isn't a value visible for the user, but the applciation still 'thinks' there is a value in it: the Text-property remains the last value, just like the SelectedIndex and SelectedValue... My user should be able to chose either a value out of the list, or nothing (= empty combobox). Does anybody knows how to do this? And with which event I can trigger this, because the MyComboBox.SelectedIndexChanged doesn't work on such a moment...

    - implement a Join between 2 DataTables (Dynamic SQL generation is not supported against multiple base tables) Hi, For my VB.NET application I have the following situation: 2 tables on my SQL Server: tblAccounts and tblRules. For each Account there are many Rules (so tblRules is linked to my tblAccounts by the Account). In the tblAccounts thee is a field Company which occurs many times (there is more than one Account for each Company:). Whet I want to do on my Fom is this: I have a combobox with all my company's in it. When I choce a Company in it, I want it to give me all the Rules for all the Accounts that this Company has. I tried it like this: 'TblRULES strSql = "SELECT * FROM tblRules INNER JOIN tblAccounts ON tblRules.Account = tblAccounts.Account" Dim cmdSql As New SqlCommand(strSql, conSql) dadRules = New SqlDataAdapter(cmdSql) Dim cbSql As New SqlCommandBuilder(dadRules) cbSql.GetUpdateCommand() dtsRules = New DataSet dadRules.Fill(dtsRules, "tblRules") Unfortunately this gives me this error: Dynamic SQL generation is not supported against multiple base tables. at System.Data.Common.CommandBuilder.BuildInformation(DataTable schemaTable) So I guess it's not good to put a join in a SqlCommand and try to do an Update afterwards on it. The 'good' way should be to somewhere be able to put tblRules and tblAccounts as two different tables in my DataSet, and perform the Join n the DataSet or something like that when I need to do a search on the Company. does anybody knows how to do this? Or to get rid of that error? I just need the best way to get this working! Thanks a lot in advance! Any help will be really appreciated!

    - Catching exceptions thrown by an MDI Child Form separately Hi All, How can you capture unhandled exceptions thrown by an MDI child form separate from the entire app? I have an application-wide exception handler to catch crashes by doing the following in my Application entry point: Public Shared Sub Main() 'Explicitly set apartment state to Single Thread Apartment (STA) System.Threading.Thread.CurrentThread.ApartmentState = System.Threading.ApartmentState.STA Dim eh As New MyExceptionHandler() AddHandler Application.ThreadException, AddressOf eh.OnThreadException Application.Run(New Form1) End Sub The form that I'm using to handle this reports/logs the exception and closes down the application. This works perfectly. I now want to enhance this functionality by catching unhandled exceptions within individual MDI Child forms so that I can close down just the child form and not the entire app. I'm having trouble isolating the exceptions thrown by the child forms separately. Does anyone have any tips on how best to do this? Thanks, --Josh Tag: Set Position of Window for Application When Launching from VB.NET Tag: 75821

    - Owner draw on the MainMenu and MenuItem Like most fans of eye candy, I've always thought the standard MainMenu control was a bit drab. After looking at third party components, I decided to see if I could brute force it into looking nice. I set the owner draw on the menu items to true, and draw the MenuItems differently depending on whether or not their selected, thus providing nice Outlook 2003 menu styling. The only problem is, there is no 'unselected' event, so I can't redraw the item when the mouse or keyboard has moved elsewhere. The only thing I could find that semi-worked, was to call an internal method on the MenuItem object to force a redraw. This works OK for everything apart from the root level MenuItem. When I try this method on the root level MenuItem it, for want of a better phrase, spags out and messes up the painting of the whole form. Not grumbling too much, it is afterall an internal method. Anyone know of a way to work with the MainMenu et. al. classes to make them look nice rather than replacing them?

    - combobox not clearing I have a form with 4 combo boxes and several text boxes. All combos are filled in the form load event. The first combobox contains names and this is the code to fill it: 'istantitiate data tier object mobjUnityGroup = New UnityGroupData 'get the list of names from the data tier dvNames = mobjUnityGroup.getNames With cboName .DataSource = dvNames .DisplayMember = "Name" .ValueMember = "ChildID" .SelectedIndex = -1 End With All other combo boxes are filled at the same time and the same way (with different datasource, display member, valuemember). I select a name and in the selectedindexchanged event, the fields are filled in and bound to the form. That works fine. However, after editing the record and saving, by clicking the Save button on the form, I wish to clear all fields, including the combo boxes. All combo boxes clear except the cboName. I another procedure I am setting all combo boxes' selectedindex = 0 and then selectedindex = -1 per the bug. All works fine except for the name combo box. I am getting an error "Object reference not set to an instance of the object" Anyone have any idea why this is happening?

    - RichTextBox Error with AppendText() I receive an error: "Object reference not set to an instance of an object." when having this code call which makes no sense as this is a richtextbox control. I have also placed the trace of this which seems to show this error occurs within RichTextBox but it doesnt fire the catch. I had to put a separate startup block in order to even catch this error - otherwise if it was in the main form it would just fail and disappear with a Windows Forms error.

    - Copy DataRows to Typed DataSet Hello, I developed a custom Windows control that displays a data grid of all orders for a customer. Since the control only needs to use the Orders table within the parent data set (along with the customer ID to filter), it seemed logical to only give the control what it needs. That's my reasoning for the code below... \\\ Public Sub New(ByRef Orders As myTypedDataSet.OrdersTable, _ ByVal CustomerID As Integer) MyBase.New() InitializeComponent() dsLocal.Orders = Orders _Customer_ID = CustomerID End Sub Private _CustomerID As Integer Private dsLocal As myTypedDataSet Private Sub ctlOrdersForCustomer_Load(ByVal _ sender As System.Object, ByVal e As System.EventArgs) _ Handles MyBase.Load myDataView.Table = dsLocal.Orders myDataView.RowFilter = "CustomerID = " & _CustomerID.ToString myDataView.Sort = "OrderDate DESC" myGrid.DataSource = myDataView End Sub /// My problem is that I can't pass the Orders table as an argument because it is part of a typed data set. VS.NET complains about dsLocal.Orders being read-only in the following statement of the constructor: dsLocal.Orders = Orders How can I set the local typed dataset table to the incoming parameter? I've also tried the Copy, ImportRow, and LoadDataRow methods with no luck. Does anyone know how this can be done? Thank you very much!

    - Finding all controls of specified type on a form I need to find all instances of a specific type of control on a Windows Form -- for example all DataGrids. The code I came up with is this: foreach(Control ctrl in this.Controls) { if(ctrl.GetType() == Type.GetType("System.Windows.Forms.DataGrid")) Console.WriteLine(((DataGrid)ctrl).Name); } This code has two problems. Something's wrong with the type checking, because it doesn't find any DataGrids on a form. Even if it did work, the second problem is that this would find only DataGrids put directly on the form (in the Form.Controls collection), but a Grid can also be in the ControlCollection of a GroupBox or some other container. How to loop through all controls in a form regardless of their parent control? Best regards, Joe Tag: Set Position of Window for Application When Launching from VB.NET Tag: 75766

    - saveFileDialog - bug & question Ok, I finally got to .NET development after a long break and i decided to write an app :) I started with functionality classes, so my app is currently console, and what it did (at work) was do something, get big xml document assembled, and then prompt the user for sme path to save it to and save it. Here's the basic code (sorry, it's not indented correctly, I posted right from VS and it doesn't seem to keep indent; well, it is small and simple anyway): public static int Main(string[] args) { XmlDocument xmlDocument = new XmlDocument(); FileSystemInfoLister xmlFS = new FileSystemInfoLister(); xmlFS.Extension = "mp3"; xmlDocument = xmlFS.GetFileSystemInfoList("e:\\"); SaveFileDialog saveFileDialog = new SaveFileDialog(); saveFileDialog.Filter = "xml files (*.xml)|*.xml|All files (*.*)|*.*" ; saveFileDialog.FilterIndex = 1; saveFileDialog.RestoreDirectory = true; saveFileDialog.OverwritePrompt = false; saveFileDialog.DefaultExt = "xml"; if ( saveFileDialog.ShowDialog() == DialogResult.OK ) { xmlDocument.Save(saveFileDialog.FileName); } return 0; } The classes finsih functioning and the program hangs up. Console window is up and nothing's happening. If oyu break it, turns out, it is hanging on "if" line. I tried moving showdialog to separate line before if - it is hanging on it. If you step into, step over or continue, it continues hanging; break it and it is on the same line. No dialog appears. What's happening? Oh and btw, there's addtional problem with dialog. When it worked (at work ;) ), the dialog behaved strangely without saveFileDialog.OverwritePrompt = false; line. Namely, it returned "Cancel" result when I picked existing file and confirmed that I want to overwrite it. Why's that?

    - Making updates to DataTable/DataGrid from within another thread Hi all! In my app I implemented a separate worker thread that handles network communication using Net.Sockets. It needs to make updates to a DataTable object, which is displayed to the user by a DataGrid control. The DataTable object is a 'public static' field instantiated within context of the main thread. The problem is that if I add a column to the DataTable from within the worker thread (eg. different thread than where the DataTable and DataGrid reside in), all columns suddenly disappear from the DataGrid view for some reason; Controller.dataTable.Columns.Add(new DataColumn("TestColumn")); If I move this code to the main thread, it works fine. After adding new column, I looked at dataTable with debugger and it seemed fine. So the culprit must be the DataGrid control. Do I need some kind of thread synchronization?

    - Databinding COM object properties When attempting to add databindings between a simple COM object properties and text box fields, I get the following error: Unhandled Exception: System.ArgumentException: Cannot bind to property or column Id on DataSource. Parameter name: dataMember at System.Windows.Forms.BindToObject.CheckBinding() at System.Windows.Forms.BindToObject.SetBindingManagerBase(BindingManagerBase lManager) at System.Windows.Forms.Binding.SetListManager(BindingManagerBase bindingManagerBase) at System.Windows.Forms.ListManagerBindingsCollection.AddCore(Binding dataBinding) ... I have a trivial form that contains 3 text boxes (id, first name, last name) and the form class instantiates the COM object in the constructor. Also in the constructor, I add the databindings: public Form1() { InitializeComponent(); m_edtId.DataBindings.Add("Text", m_user, "Id"); m_edtLastName.DataBindings.Add("Text", m_user, "LastName"); m_edtFirstName.DataBindings.Add("Text", m_user, "FirstName"); } The COM object has get/set for these three properties and works fine if I don't use databinding. Also, if I replace the COM object with a managed class that has these properties, I don't have any problems with the databinding. Thanks for any assistance.

    - Deployment Question (networked) Hi all, I'm relatively new to .Net and especially the Windows side of it (I come from a web background). I have recently started dabbling in Windows apps - one thing I would like to be able to do is install my application across several PC's on a network, can anyone suggest how this could be achieved? My application will be using a small xml file as a config file - I was going to have one of these present for each install of the application - however I think it might be better if this was in one central location (ie on the server) so that a) a normal user would be unable to change it, b) when it needs changing its only changed in one location - not across 30+ client PC's etc. Can anyone advise as to whether this is a good approach - or whether having a config file for each installation would be better - a bonus of this would be if the server was ever to fail the client apps could still run as they'd have their own config files etc. I have used the Install Wizard in Visual Studio once - and it seemed very straight forward, and put a pretty front end to the install process - I have no idea however whether this is particularly customisable, ie, what if I want to still have a file on each install (client) that tells it where to get the main config file from - this should be perhaps something entered during the install yet the Wizard did not seem to give any options for adding extra information(ie, asking questions) during the install process - other than the location of where the application would be installed. Any information at all on this subject would be appreciated. Kind regards Rob Meade Tag: Set Position of Window for Application When Launching from VB.NET Tag: 75762

How do you set the position of an application window when it is lauched from
VB.NET?
My application needs to check for the number of Microsoft Terminal Services
running, then close all but one and position the remaining one on the second
monitor for a dual screen system. If there isn't an instance of MTS running,
then I'll launch a new instance of MTS and position its window on the second
monitor.

I've searched under the left, top, width and height properties, but cannot
find the proper syntax to accomplish...
Thanks in advance.
