• .NET Development Not able to use GetDataTableSchema

  hi, .Net 2.0 has added a new method to the DataTable class, GetDataTableSchema ( ). Not able to use it though. Even msdn docs dont provide an example. I will really appreciate if you can provide me with any simple example. Thank You. This method returns a XmlSchemaSet instance containing the WSDL that describes the DataTable for Web Services.

• Commerce Server Feedback: reorder CatalogCreate.sql

  Just a bit of feedback here. When i execute \Program Files\Microsoft Commerce Server 2007\CatalogCreate.sql it throws a bunch of warnings along the lines of "Cannot add rows to sysdepends for the current object becuase it depends on the missing object 'dbo.ctlg_GrantPermissionIfExists'. The object will still be created." When I check the db after the script has completed, the missing object is there, it just needs to be moved to an early position in the script so these warnings aren't thrown. Michael. Max, When i execute that script on a blank database it runs successfully but i get all of these messages: Cannot add rows to sysdepends for the current object because it depends on the missing obje ...Show All

• Visual Studio 2008 (Pre-release) How to: Implement aggregates with GridView and Grouping

  I'm trying to create a sort of Outline Grid. Where you can group and the Grouped item contains the sum. Eventually I need to include a Min and Max for dates. +/-Group1 20 50 item1 10 40 item2 10 10 I was thinking that extending the CollectionView and CollectionViewGroup might work, but before traveling down that long road I figure I'd see if anyone has had experience with this sort of thing. The goal is so that when you're creating the GroupItem style, you'll be able to reference ItemSum, just like ItemCount that currently exists. There is still an issue as to what column you need to sum, which I haven't really thought out yet. The other issue is that I'll need the group data to refresh when the item data changes. ...Show All

• Visual Basic Run-time error '-2147467259 (800004005)'.... HELP please!!!

  I created a simple database program using VB 6. I use ADO connection. Though, I used DAO too for my DBGrid. I also use classes and modules. I was able to run and compile this program.

• Windows Forms Problems modifying context menu on the fly

  I have been trying to modify a context menu depending upon the view a user choose in a window. I have added a context menu in the design view and added 3 menu items. On load I set one of these items to be either invisible or unenabled (I have tried both) however in the 1st view I still get all 3 appearing. I can set this to unenabled/invisible in the design view and it works fine. As I cycle through the views (choosing the view based on the choice made on the context menu) I try to set various other items to unenabled/invisible. This does work however it does not set the correct one to unenabled/invisible, and seems to choose the one that it sets invisible based upon the 1st choice you make in the context menu. For example I have my contex ...Show All

• Visual Basic How to check if an Array contains a string.

  I want to search through an array and find out if a certain string is contained within. But, Array does not have a Contains member so I do not know what else to use. Thank you, Troy L What do you mean by generic list of string My array is a string array, it contains only strings. I am currently using: For Each Item As String In MyArray If Str <> Item Then CbBox.Checked = True Else CbBox.Checked = False Exit For End If Next Str is the string that I am searching for. Basically it seaches the strings in MyArray and if it finds one that matches Str then it unchecks CbBox and exits the for statement. I do this for three Arrays and it doesn't please me. I was wondering if there was a more efficient way to search throug ...Show All

• Visual C++ Making vcredist_x86.exe run silently

  Hi I am putting a software installer together, and one step I need to take is running this app to ensure certain dlls are present on the users system. At the moment, I am placing the exe in a temp folder, running it, then deleting it. I am using the NSIS installer scripting tool, so Exec "C:\temp\vcredist_x86.exe" is the line that does the business. Is there an argument I can pass to vcredist_x86.exe in order to make it run silently (ie without bringing up any popups about what it is doing ) Curiously, I cannot run the exe from a DOS prompt. Thanks OK, so you basically should take the command line way of installing the runtime. See the link of my previous post. -- SvenC ...Show All

• .NET Development WEB service parameters styles

  Hello. I am implementing a client for a Web service defined on the JAVA server (JBoss AS). They tried to define a style for methods parameters as 'rpc' which meaning that parameters appear in the WSDL as they are defined on the server and .NET test application had problems when the number of parameters was greater than 1. Then they moved to 'document' style which forced WSDL to envelop a list of methods parameters into a structure and pass this structure as parameter. It is very inconvenient because the name of the structure is defined as a name of the method and there are other confusing elements in this solution. Can you provide any information about limitation or constraints on the list of parameters in WSDL generated by JAVA What ...Show All
