• Software Development for Windows Vista Writing Resource Managers for System.Transactions to MTS/DTC and XA

  We are trying to write a durable resource manager that works with System.Transactions. I need to use mts/dtc talking to xa where the actual database is on a remote system. I have read all of "Implementing a Resource Manager" and everything else I could find but could not figure out how to couple the .NET resource manager with xa. We have working distributed transaction code for OLEDB and ODBC using mts/dtc and xa. I really need sample code and/or hints about writing such a resource manager like this. If I understand your approach correctly, not quite -- and the issue really does end up revolving around recovery. Again, I think what you're trying for is roughly: App -> your bridge resource -> XA res ...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. I need someway to specify which of the unde ...Show All

• Visual Studio Express Editions Listbox items filtered by textbox onchange

  i have a textbox and listbox on a form. The listbox is bound to items from a database. When the user begins to type in the textbox I'd like the listbox items to be filtered onchange as he types. So according to what is being typed the items listbox will lessen according to what matches what is being typed. *This is not an autocomplete function.* Can someone please point me to some sample code to be able to achieve this Thanks ! You are correct. I am sorry that I did not check that out further before posting it. I will do some more research and post back my results. I know it can be done, but, might require jumping thru some more hoops! james aka:Trucker ...Show All

• Smart Device Development Querying SQL Server CE 3.0 with Visual Studio

  Hey all! I'm comming across fustrations with the sql querying tool that is built into visual studio 2005. I'm trying to query a Sql Server CE 3.0 database, and have dropped a few tables onto the diagram pane, and select my columns and everything queries fine. However, if I change my join between the two tables to a Right outer join, the designer automatically slaps a '{ oj ... }' around my where clause which isn't supported by sql server ce 3.0. Anytime I remove it and try to execute my query it automatically re-adds these sumbols and displays an error to me. Is there any way I can get visual studio to stop automatically adding these sql symbols when talking to a database that doesn't support them Below is the query it produce ...Show All

• Visual Studio Express Editions save as Excel file how?

  hi there i have a problem regaring to my database and MS excel... how can i save my items which you can see in datagrid into excel file I dont believe there is any default method to export the data from a datagridview control into excel. You would need to write your own process to achieve that. This would work if Excel was installed on the same machine as your application. A Simple example of writing Excel data from Vb.net. This is simply writing some values and looping using the section marked in bold. You of course will be selecting the values from either you datagridview by iterating through the rows and columns. Something like the following should work for you in writing the datagridview contents to a excel worksheet. ...Show All

• Visual C# WIA 2.0 not scanning

  I am writing a windows control that runs a scanner. Everything works fine in WIA 1.0, but when I try and use WIA 2.0 it does not. I am starting from the sample application from http://msdn.microsoft.com/coding4fun/someassemblyrequired/lookatme/default.aspx Anyway the following code finds the scanner properly, DeviceManager manager = new DeviceManagerClass(); foreach (DeviceInfo info in manager.DeviceInfos) { if (info.Type == WiaDeviceType.ScannerDeviceType) { device = info.Connect(); break; } } When I iterate through the commands, I get the following: "Synchronize" "Delete Device Tree" "Build Device Tree" None of these commands has anything to do with captu ...Show All

  Compiler Error CS0570 Does anyone understand error CS0570 'class' is not supported by the language This error occurs when using imported metadata that was generated by another compiler. Your code attempted to use a class member that the compiler cannot process. The code being called was written in Managed C++ paraphrased like so: public ref class FilePath { ...

• Visual Studio Database Expert linking and Subreports

  I went through a complete 'Walkthrough' 'Report Document Object model Logging onto a secure SQL Server database with a sub report. Suffice it to say that since am creating a custom Dataset in ADO.NET, this was the incorrect walkthrough - as it showed me a Login, connectionInfo, etc. - this was all unnecessary because the dataset schema takes care of that in the connection. It's difficult to find all the correct information because this is all so new. I'm interested to optimize the loading of a report that has 4 subreports - the method I am pasting here works, but I read something about creating a relationship with the tables in the main report - so I tried that but then I get the famous side-effect - prompt for login credentials p ...Show All

• Visual Basic Seeking Help with DBF Writer

  Hello, I following is a test class that I am writing. It is the beginning of a dbf writer that i am creating in vb.net. I have not written code to loop thru records, I just set a default field name, length and a default output. However, I am having problems with this, and am seeking advice on someone who may have written a dbf writer before. dbf output should look like this: JOBID 12345 A few things I have noticed when trying to debug, was that after running the program, and going back and readying each byte in the new file. Nothing would actually add up. For example, I specified version to equal 3, but when I read the bytes, I do not get the correct version number.. and so on. Also, my output would be something like 1234 ...Show All

• Silverlight (formerly WPF/E) WPF/e vs. HTML

  After reading Mike Harsh's blog post What WPF/e Really is . I'm kind of disappointed with the approach that the Architects are taking with WPF/e, as in that it augments HTML instead of replacing it. Why not Personaly I find that HTML slows me down in producing rich content for my users (something that WPF promises). Sure its easy, its fast, and we should keep it (not every website needs rotating letters). However, as I see .NET being used -alot- for mission critical application, I would only EXPECT WPF/e to take the fore front and upgrading the way we provide commericial services on the Internet in a fast, uniform way. Flash is doing this, Flex is not 'augmenting' the Web, its rewriting it. Share your thoughts. What w ...Show All
