    - Out of Memory Exception in a user drawn control Hello, I am drawing a control with GDI+. It contains an image which turns around a center. After turning for a while I get and "Out of Memory" Exception. I am disposing all the created objects(the ones which are used/created during turning). The image is included in the solution as an embedded resource, loaded into a stream and than created with new Bitmap. But it is always the same image and I am laoding it only once. When the Exception occurs the Control is just lost on the screen and instead i see red framed square with is crossed out. The Code where the Exception is thrown: private void OnPaint(Graphics graphics) { Matrix matrix = new Matrix(); matrix.RotateAt(Angle, m_center, MatrixOrder.Append); graphics.Transform = matrix; graphics.DrawImage(m_image, m_rect); matrix.RotateAt(-Angle, m_center, MatrixOrder.Append); graphics.Transform = matrix; matrix.Dispose(); } Thanks for any help Alex Tag: File.ReadAllText prevent write access for other processes Tag: 134342

    - load .NET assembly How does an executable (managed or unmanaged) load an .NET assembly ? A dotnet 1.0 application I'm debugging atm seems to (one computer) load dotnet 2.0 assemblies instead of the specified 1.0 version (all assembly reference in the vs2002 solution for the application point to dotnet 1.0). Due to changes in the api between these two dotnet version the application will not run properly when using an incorrect version. The computer contains dotnet 1.0 \ 1.1 \ 2.0 \3.0. Any hints on an utility or article that could shed some light on this situation ? Ta, Tag: File.ReadAllText prevent write access for other processes Tag: 134328

    - xmlTextReader path to file I've inherited a .NET project that I'm debugging the code to. I'm completely new to .net as well. I have a line in my code that reads an XML file, however, I cannot figure out the reference point that a relative path starts from. I.e., the following line XmlTextReader reader = new XmlTextReader( "..\\..\\..\\filename.xml" ) points to "BaseURI "file:///C:/Program Files/filename.xml" string When I step through the code even though my project is in c:\projects\... I don't want to hard code a path into the code as that wouldn't be practical. What is it starting point for the relative path and how can I change it? Thank you.

    - Looking for LINQ to SQL N-Tier example I'm looking for an example / guidelines for leveraging LINQ to SQL in an N-Tier environment. Specifically I'm looking for an example where there is a presentation layer, an application layer, and a database. There are plenty of examples showing how to create LINQ objects and then connect them as datasources directly to web controls that consume datasources. I"m looking for a way to create the LINQ objects on the application server and then propagate them to the web server to have them consumed as datasources there. Any help is appreciated, Thanks.

    - Workflow transition restrictions Hello. I have document workflow. I implement this feature by wwf using State Machine Workflow (http://files.rsdn.ru/36601/demo.JPG). In our system there are a lot of users with different roles. The question is: How can i restrict workflow transitions for specified user-roles? For example: 1. Any user can create documents. 2. Super user can create and process documents. By this code I can analyse specified workflow instance and get all possible state transitions. private static void DumpStateMachine(WorkflowRuntime runtime, Guid instanceID) { StateMachineWorkflowInstance instance = new StateMachineWorkflowInstance(runtime, instanceID); Console.WriteLine("Workflow ID: {0}", instanceID); Console.WriteLine("Current State: {0}", instance.CurrentStateName); Console.WriteLine("Possible Transitions: {0}", instance.PossibleStateTransitions.Count); foreach (string name in instance.PossibleStateTransitions) { Console.WriteLine("\t{0}", name); } } Is there any possible solution to restrict transitions between states of existing workflow for specified user roles?

    - trying to pass a string back to main form from a class I'm creating a GUI for the NetSend service. I created a class called Netsend. In there are to functions. The send function is public and the NetMessageBufferSend function is private. Below is the code I created for this class. Public Class Netsend Public Function Send(ByVal sTo As String, ByVal sMessage As String) As Integer Dim iReturnValue As Integer Dim sReturn As String Dim bBuffer As Byte() = Encoding.Unicode.GetBytes(sMessage) If sTo.Length And sMessage.Length <> 0 Then iReturnValue = NetMessageBufferSend(Nothing, sTo, Nothing, sMessage, sMessage.Length * 2 + 2) Select Case iReturnValue Case 0 sReturn = "Successfully sent message to " & sTo Case 2100 sReturn = "" Case 2273 sReturn = "The message alias could not be found on network for " & sTo Case 2136 sReturn = "General network error occurred for " & sTo Case 5 sReturn = "Error: Access denied for " & sTo Case 87 sReturn = "Invalid parameter for " & sTo Case 50 sReturn = "This is not a supported command on targert " & sTo Case Else sReturn = "Unknown return value for " & sTo End Select Return sReturn Else Return "Error: Either no computer was selected or message was blank." End If End Function <DllImportAttribute("Netapi32", CharSet:=CharSet.Unicode)> _ Private Shared Function NetMessageBufferSend(ByVal servername As String, ByVal msgname As String, ByVal fromname As String, ByVal buf As String, ByVal buflen As Integer) As Integer End Function So my form creates a new object for this class and calls the Send function and passes the correct arguments, Computer name and message. Then "send function" then validates and calls the Private function NetMessageBufferSend and assigns the return to var iReturnValue. the "Send" function runs through a case statment to set the value of sReturn. Then that value of sReturn is returned to the main form. When it tries to return the value back to a string var on the form, i get a invalid cast error saying that it is expecting a integer. I am able to return a integer to the main form, but why cant I return a string? Tag: File.ReadAllText prevent write access for other processes Tag: 134293

    - Assembly path Hi everyone, I have a windows service project, that references the assembly from a web project. My problem is that on the production server, the service's directory path points at the system32 folder, and not the folder where its own .exe fil is located which would be the normal behavior. This means that it cannot locate its config file, nor the dll from the referenced assembly. I can fix the config problem by loading the configuration explicit from a hardcoded path (ugly). The assembly is another matter though, and loading it into the GAC is not an option. I could drop the referenced dll into the system32 folder, but that is about as ugly as it gets. I've made a number of services before that never had this problem and the main difference here is the reference to an external dll. Anyone have any idea how to "fix" the service's startup path?

    - Service installer fails on "repair" install I have a VS Setup project for a C# Windows Service. In the Control Panel's "Add/Remove Programs" applet, my service appears with a change button, which when clicked gives an option to repair the install. If I do that, I get an error message saying "The specified service already exists" and the install fails. It seems like the repair install ought to be more forgiving. If someone is repairing an install, stuff could be in some random state of chaos, but if the service is fine, the repair will fail. Similarly, I've noticed that if the uninstall successfully removes the service but fails in some later step, rerunning the uninstall also won't work. This time the uninstall is unhappy because you're trying to remove a service that doesn't exist and the process fails again. Is there some way for these scenarios to work in a more robust way?

    - No Error Message when .Net Configuration 1.1 Tool is open. Anyone understand? So i am using this 3rd party API in one of my applications. Both the DLL for the API and my executable sit on a network drive for everyone to access. Therefore all of the machines in my company have code groups set up to allow the application to run. For a large majority of the 80 or so machines, this works beautifully. I've identified 4 machines that give this error: "Exception Occured. Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=nuetral, PublicKeyToken=b77wrfewreq34rfq failed." When comparing the code groups on the different machines, I see that they are all the same. On the machines the application works, it works 100% of the time. On the machines it does not work, it fails 100% of the time, aside from one case. When the .Net Configuration 1.1 Tool in "Administrative Tools" is open, you do not get the error message. It's as if having the tool open puts the machine into some other state and allows my app to run properly. Then when I close the tool, i go back to getting the error message.

[...] We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). [...] The source code will be released under the Microsoft Reference License (MS-RL). You'll be able to download the .NET Framework source libraries via a standalone install (allowing you to use any text editor to browse it locally). We will also provide integrated debugging support of it within VS 2008." ---------------- Sounds great to me!

    - [WPF]: Tab Control and TabItem (focus?) woes.... Here is a XAML snippet (which would run in XAML Pad as well): <TabControl> <TabItem Header="One"> <TabControl> <TabItem Header="OK"> <Button Content="OK"/> </TabItem> <TabItem Header="Not OK"> <Button Content="Not OK"/> </TabItem> </TabControl> </TabItem> <TabItem Header="Two"> <TabControl> <TabControl.Template> <ControlTemplate TargetType="{x:Type TabControl}"> <Grid KeyboardNavigation.TabNavigation="Local" SnapsToDevicePixels="true" ClipToBounds="true"> <Grid.RowDefinitions> <RowDefinition Name="RowDefinition0" Height="Auto" /> <RowDefinition Name="RowDefinition1" Height="*" /> </Grid.RowDefinitions> <DockPanel> <StackPanel DockPanel.Dock="Right" Orientation="Horizontal" Name="HeaderPanel" ZIndex="1" KeyboardNavigation.TabIndex="1" IsItemsHost="true" /> <Label Content="Something" /> </DockPanel> <ContentPresenter Name="PART_SelectedContentHost" Grid.Column="0" Grid.Row="1" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Margin="{TemplateBinding Padding}" ContentSource="SelectedContent" /> </Grid> </ControlTemplate> </TabControl.Template> <TabItem Header="Apple"> <Button Content="One Apple a day, keep the doctors away"/> </TabItem> <TabItem Header="Carrot"> <Button Content="One carrot a day, ho well, nothing special"/> </TabItem> </TabControl> </TabItem> </TabControl> Where every time you select the TabItem "Two" (in the toplevel tab) the inner TabControl would change its selected item. (every second time it will be "Apple" every other second time it will be "Carrot") Why does the inner tab changes? How to work around this bug?

    - Embedded file to clipboard Hi, I have a file which I would like to put on the clipboard so that when it is pasted in Word or WordPad the file appears as an embedded file. I can use the RichTextBox to generate RichText with different formatting, add it to the clipboard, and it appears fine when inserted in Word but I can't find any methods that allow me to insert an embedded file. Is there any way to do this? /Andreas Tag: File.ReadAllText prevent write access for other processes Tag: 134172

    - Toolstrip and MDI application I am trying to get write an MDI application running using the ToolStrip control(s). I have the application running with types of two form. Each form represents a type of document. Each has its own custom menus and toolbars. The MDI application runs up and I create new documents of each type. When a form is activated, dot net merges the menus and the app I merge in the toolbars using RevertMerge and Merge. One of my forms has about 6 toolbars, the other has 2. When I switch between the two document type, the toolbars change position; I activate form1, move the toolbars using the mouse, activate form2, then switch back to form1- the toolbars have moved. I am also having problems saving and restoring the positions of the toolbars using ToolStripManager.LoadSettings and ToolStripManager.SaveSettings. This showing the same behaviour (although it may be caused simply by switching between the windows). Has anyone successfully implemented an MDI app using these controls? I have a test app if anyone would like to see it - where the best place to post it? Paul Wardle Tag: File.ReadAllText prevent write access for other processes Tag: 134152

    - How to call C# callbacks from C++/CLI? Hi, Tried searching Google on this topic but not many came up. Basically I have a C# GUI client that wants to receive 'notifications' from a worker DLL (which is implemented in C++/CLI). So far, from C# I am able to call any method directly in C++/CLI DLL. But I would like to have the C++/CLI invoke some callback methods from within C# (some event notifications so that the GUI updates its UI). In the old days using C/C++, I could do this easily by passing a class object ptr to the DLL and have it invoke callback methods declared in that class. Can I do the same thing in .NET? Since there is no header file, I don't know how to 'tell' the C++/CLI component which C# callback methods to use. Thanks. Tag: File.ReadAllText prevent write access for other processes Tag: 134148

    - Fatal Execuation Error - any workarounds available? or help debugg We have a .NET application using Windows Forms. This application terminates unexpectedly once or twice a day for our customers. The following entry is listed in the event log: .NET Runtime version 2.0.50727.832 - Fatal Execution Engine Error (7A0592A2) (80131506) This problem appears to have started recently in the past 1 or 2 months. Is this a known issue, and if so, are there any workarounds? I am really at a loss as to how to deal with this problem. How do you suggest I go about debugging or troubleshooting this issue?

    - ReplacerStream Hi, I need to use a stream that I can configur to replace some input string with another. It is probably not very difficult to do but I can't imagine that this has not been written dozens of times before. However I can't find something like it on the internet. Does anyone know of such an example or has code? Or should I be creating an impelementation of TextWriter/Reader in stead of of Stream?

    - XAML, dynamically created RadioButton, and WordWrap? I have an app that presents a variable number of radio buttons (with variable text) that are created dynamically on a HeaderedItemsControl. As far as I can tell, the RadioButton doesn't supports (word or otherwise) wrapping, but will present multiple lines of text, so I could implement word wrapping by inserting NewLine(s) if I could just determine how wide my text is... It is occasionally too wide for a single line, and could theoretically be several lines. I would *really* like to do this when I create the controls and assign the texts and handlers (this is after the window has been shown), but while I can get the initial DesiredSize AND the first iteration after that, it seems I can't get there from here: It won't tell me the size until the layout is final - but the layout won't be final until I know the size of my display text. What can I do (.Net 2.0 w/FW 3.0, VB preferred, but except for some differences in threading and delegates, I can deal with C#)?

    - Accessing UNC file share with credentials? From a .NET 1.1 app: need to access a file share on a remote server by its UNC path, i.e., \\server\folder\subfolder\, using specific username and password. The problem is that the credentials are local to the remote server. Therefore, impersonating that user when accessing the share is not possible. One solution is to map a network drive using the credentials, but it seems kind of ugly and old school. Is there any other way? Thanks! Tag: File.ReadAllText prevent write access for other processes Tag: 134121

Hi,

I have noticed that File.ReadAllText prevents other processes from writing
to the file while reading. It seems like the FileShare enum is set to Read
rather than ReadWrite. This is a bug in my opinion.

Hello, Marthin!

I do not think that its a bug. When you're reading from file you do not want
anybody to mess something in it, right?
That is if I'm reading _whole_ file I have to be shure that nothing will
change in it.

However, there may be scenarios when simultaneous read and write to the file
are permitted. When you have such scenario you'll have to use FileStream.

It's not a bug. It's by design.

If you want to have more control over the file access modes, don't use
the File class. It is intended only for the basic scenarios.
