• Software Development for Windows Vista Installing MSDTC in a 2003 Cluster - Best Practice for SQL 2005?

  The KB article How to configure Microsoft Distributed Transaction Coordinator on a Windows Server 2003 cluster states "When creating the MSDTC, moving the resource group into a group other than SQL Server or Exchange Server group is highly recommended. Creating the MSDTC resource in its own resource group and assigning it to a separate cluster group keeps the resource highly available." We currently have MSDTC in the same group as SQL Server 2005. We also made the SQL Server resource dependant on the MSDTC resource, since the applications that connect to this SQL instance use DTC transactions. Besides preventing unnessesary MSDTC failovers (as stated in the KB article), is there any downside to not configuring MSDTC within ...Show All

• Visual C# DataGrid + threading help - 'Controls created on one thread cannot be parented to a control on a different thread.'

• Visual Studio Team System Can I use the XML/XSD schema as a source for data genaration?

  I have some XML/XSD schema which has table definition. Can I use this schema in place of the RDBMS table for generating the data And is it possible to have this data generated in the XML file Right now we either reverse engineering the schema from database or import it from Sql Script. And there is no direct way to import the schema from XML/XSD. A workaround is that you can write your code to create sql script so that it can be imported. For data generation, there is no direct way to generate data into xml file. You can generate data into the database first and then export them into xml file. Thanks, ...Show All

• Visual C++ Returning the memory allocated for a pointer

  Hi! I would like to ask if there is a function (or some way) to return the memory allocated for a pointer. Example: char *s = new char[69]; cout << DesiredFunction(s); //I would like this to print 69 Thank you in advance. bookysmell2004 wrote: I would like to ask if there is a function (or some way) to return the memory allocated for a pointer.

• Windows Forms another System.Windows.Forms.HScrollBar question

  hi, i noticed that the System.Windows.Forms.HScrollBar renders a little differently from the scroll bars that are present on a control with the AutoScroll property set to true. The difference is in the way the arrow buttons render, or maybe i should say, don't render. when pressed they just disappear. with the autoscroll version they are rendered as a pressed button shaded a tad darker. what gives thanks, scott hi, now i spent some time duplicating this and looking for the difference between my working implementation and my duplicated implementation. i said earlier that i could not duplicate the problem, today i was able to. here is what did: create a simple form with hor and ver scroll bars from the to ...Show All

• Smart Device Development control.invoke

  Hi all. Can someone push or punch me in the right direction here Using the CF 2.0 I have an application that is doing an async poll of a TCP listener for data. When the data arrives, I want to update certain forms with the values. In a nutshell, The data arrives. I determine what type of data it is and where it should display. I populate properties of a class with the data. I then raise an event to signal the data is here and the properties have been populated. It is here where my problems start. Based on the the data I will determine what form I need to interact with. I need to call a sub from within that form to populate the controls on it. I was using invoke to call the sub , but the data would not display because the ...Show All

• Visual C# Cast Problem with ArrayList.ToArray()

  I am using an ArrayList (stuck in 1.1 land) to build an array dynamical, but because it needs to be serialized (and therefore typed) I am converting the completed ArrayList to a typed Array[]. Here is code that works: enrollment[] manifest_final = (enrollment[])manifest.ToArray(); And here is code that give an Invalike Cast error: ( enrollment)manifest[ i ]).lectures = (eLecture[])((enrollment)manifest[ i ]).tempLecs.ToArray(); The second line deals with an arraylist 'tempLecs' inside each enrollment object. I don't know if that scope is part of the problem. Does anyone have any ideas Thanks in advanced! Andrew Update: //create typed arrays out of ArrayLists for(int i = 0;i < ...Show All

• Visual Basic Exe takes more than 35 sec. to load

  Hi freinds, I am using vb.net 2005. The problem is when i install the project on the clients PC it take more that 30-40 sec to load. Why does it takes so much time as compared to vb 6 applications. Is there any other way to improve the performance Please Help me out. Thanks Puneet Minda Puneet I think what ReneeC is saying is that a 35sec load time is not typical. It is likely something specific that you are doing in your application. To get the help you need, you might want to describe your application a little better. After such time, one of these brilliant folks (like Renee) might be able to help you. ...Show All

• Visual Studio Object data source in a different project

  Hi, This is my first go with Crystal that comes with VS 2005, although I've used Crystal and VS 2003 previously. I'd like to use business objects as the source of my data. These business objects are in another project, which is a library of bo's. This library is referenced in my UI (Windows Forms) project. I read the tutorial starting on page 354 in this document http://www.businessobjects.com/global/pdf/dev_zone/cr_vs2005_walkthroughs.pdf That seems like it would work for me, but my objects are in a different project and so do not automatically appear under the "Available Data Sources" in the Standard Report Creation Wizard.

• Windows Forms adding a User Control programmatically to a panel control.
