• Software Development for Windows Vista restoring all workflows from persisted storage

  Within the WF runtime, i see runtime.GetWorkflow(Guid) and instance.Load(). However, the typical use of my app would be that the user turns it off occasionally (this would prompt me to call Unload() on all the workflows), and turns it back on (this would necessitate restoring all the persisted workflows) How do i ask the runtime to restore all the persisted workflows I don't see a: runtime.GetAllWorkflows() Is there a way to do this Thanks. No, in the case of runtime shutting down, it will in fact iterate on all loaded instances and use whatever persistence service in place to persist the insances before shutting down. We may look into making the runtime load instances on startup in fut ...Show All

• Windows Forms Error : DataTable internal index is corrupted: '5'

  Hi all I'm getting " DataTable internal index is corrupted: '5' this error when I'm modifying the content in a datatable. I'm running 4 threads at a time, and each thread executes a common method(one method for all threads). In that method I'm changing the Datatable , there I'm getting this error. Is there any problem with multiple threads accessing same table at a time Can Anybosy help me in this. Thanks in advacne What I am thinking is more than one thread is trying to modify the datatable at once causing the error.  Try to lock (or synclock vb) the datatable so only one thread can modify the table at a time. Try something like this lock (YourDataTable) { // do something with the ...Show All

• Visual Basic Pointer to an image in memory

  I have bit a code where I need a intptr value for a byte array, and I have no idea how to get the pointer to the byte array. Dim myImage() As Byte = conv.GetImage image = Drawing.Image.FromHbitmap(<POINTER TO myImage>) I"m not even sure this will work, but an answer will help. Can anyone help me here Thanks. I might be wrong but .NET is a "safe" language, you do not have direct access to memory. Only C# has the unsafe keyword that let you play with memory. Here is a code that show how to copy the byte of an image to a byte array http://www.eggheadcafe.com/PrintSearchContent.asp LINKID=799 Don't forget to copy the array back to the image. ...Show All

• Visual Studio 2008 (Pre-release) How to pass parameters to a DataBinding in XAML? - I want (need) to seed the construction of the DataBinding source object.

  I have a set of generic (generalized) DataBinding source objects, each of which maps to a different UI control type (eg. collections for ComboBox, single value for checkbox, etc.). <CheckBox.IsChecked> <Binding Path="Value" Source="{StaticResource SingleValueBinder}" /> </CheckBox.IsChecked> or <ComboBox Name="MyCombo" Height="21" Margin="20,20,20,20" ItemsSource="{Binding Source={StaticResource ItemsSourceBinder}, Path=Values}" IsSynchronizedWithCurrentItem="True"> </ComboBox> These objects are basically serving as adaptors and internally map to a host of specific object values.

• Microsoft ISV Community Center Forums Commandbar ICon (Excel VBA )

  I m making one AddIns for Excel. I have added a CommandBar. Now I can assign the ICon to CommabBar Using Pasteface method. But this is creating some Problem for me. So is there Any other way to assign Icon to Commandbar... You don't describe the problems you are having, so it's hard to make a sensible suggestion. In later versions of Office (2003 and perhaps 2002), you can modify the picture and mask propery of the button. In earlier versions you are stuck with pasteface, but you may be able to improve the quality of your image. The picture and mask technique is described in Professional Excel Development by Bullen, Bovey, and Green. This book is a must-have for any serious Excel developer. - Jon ------- Jon Peltier, Microso ...Show All

• SQL Server Slow Report

  As I sit here waiting for a test run of the report to complete, I'm forced to wonder why it's taking over 10 minutes... so far. The query itself, when run through Management Studio takes about 50 seconds, so why would it take over 10 minutes to generate the report   It's the only query being run, and it's not doing anything especially tricky with the data.  It's all actually being processed in the query, returning some counts and displaying them in a simple list. Any thoughts EDIT:  I should mention that the query itself isn't very simple, so I can understand the query itself being slow... just not the report being 10 times slower than the query in management studio. Could you describe the report and the datas ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MouseState.ScrollWheelValue always 0

  Hi, I want to use the mouse scroll wheel to zoom. In the tutorials I have tried, MouseState.ScrollWheelValue works fine, but in my own test program it always returns 0. The main difference I can think of in my test program is that I am not using the Game class. Instead I create my own GraphicsDevice and use a standard System.Windows.Form. Is there any initialization I have to do for MouseState.ScrollWheelValue to work This is the code for reading mouse state. All of it works, except mouseState.ScrollWheelValue which always returns 0. MouseState mouseState = Mouse.GetState(); myMouseLocation = new Point(mouseState.X, mouseState.Y); myIsLeftButtonPressed = mouseState.LeftButton == ButtonState.Pressed; int currScrollWheelValue = m ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. some simple noob question

  Hi Well.. i learned c#.. and i said what the heck .. why not learn direct x.. and i have some problems understanding cerain things like: if i have like 30 meshs .. and the vertex buffer.. i have do render seperatly every mesh plus the vertexbuffer sorry if i sound crazy.. but.. need some help.. The normal way is to render each mesh with an own draw call. There are some tricks to render multiple objects with only one call but as you are a beginner you should not care to much about this now. With mesh you mean the mesh class In this case it manage the vertex buffers for you (create, fill, select, destroy). You only need to call “DrawSubset”. ...Show All

• Software Development for Windows Vista UAC - Elevated Com Moniker

  I'm trying to make a library that I write Vista compatible. UAC is proving a headache because my library writes and modifies data that needs to be shared across all users. So my writes and modifications cannot be virtualized. However, since my library is not a stand alone app itself, I can't specify that virtualization be disabled for the whole app. So . . . what I need is to request elevation credentials of the user on the fly when my library reaches the point of needing to do a file write. From my reading, the cleanest way to do this seemed to be to isolate my writes into a COM object and then use the Elevated COM Moniker techinque. My COM knowledge is spotty, but this didn't seem to complicated a project, so I've given it a go. Wi ...Show All

  We've some XML docs coming in daily. Task is to load them into SQL Server tables.

(Initially, we can use an existing table and then populate from xml document) Can somebody outline the steps in achieving the goal Can it be done using SQL Server alone or we need to use other technology like .NET Can it be automated completely using T-SQL Also, how do we use SQLXMLOLEDB.4.0 from SSIS to bring xml into SQL Server Any inputs are highly appreciated.
