• SQL Server xml data source, not sure why i'm losing data

  I created a SSIS package, it calls for web service which creates an .xml file, then I use XML source to point to the xml file and want it to be imported to a table, but data won’t go into the database table. I believe it’s something wrong with the xml file format, but don’t know how to change it. Here is what the .xml file like: < xml version="1.0" encoding="utf-16" > <DataSet> <xs:schema id="NewDataSet" xmlns="" xmlns:xs=" http://www.w3.org/2001/XMLSchema " xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true"> <xs:complexType> ...Show All

• Windows Forms how to avoid flickering in repainting

  hi, I have developed a user control , in that i have overridden the onpaint method. whenever a mousemove event happened i am invalidating the control using Invalidate(). The thing is it is flickering often, Can anyone explain, 1) why the flickering occurs ( since internally every control like buttton, trackbar are repainted everytime right...correct me if i am wrong ) 2) how to avoid the flickering( it should not contain even 1% flickering in the control ) thanks singam. Flickering occurs like this: 1) something is painted (usually the background of the color) 2) user sees that 3) another thing is painted (let's say a line) 3) user sees what has been painted in step 1 and the new line from s ...Show All

• Visual Basic Copy control in tabpage of trabcontrol to another tabpage

  Hello, In tabcontrol, is it possible to copy controls from a tabpage to another tabpage. The initial tabpage has 2 textbox and 1 button. The click event of button is the same in each tabpage. The purpose is to have x tabpages identical just the name of tabpage change. Thanks Ben OK, Here's a solution. Put you controls (Tetxboxes and Button on a panel control on a form) And then when the Tabcontrol - selectedindexchanged event fires then simply add the panel to the appropriate tabpage controls collection. This means you only have one set of controls which can be used across all the tabpages. In this case I have two tabs - which ever one you click on the controls will be ...Show All

• SQL Server Slow access unless administrator account

  We have an issue with accessing SQL Server 2000 where the access of data from the database is slow unless the user is logged in as an administrator to their computer. The system is as follows: SQL Server 2000 on a W2K server. Users logging into a Win 2003 domain server. Users using W2K on their workstations. Application is VB.NET using the Enterprise Library Data Block, connection pooling ON, and windows authentication. We are assuming that the issue is down to one of authentication and that when a user is set as an administrator then they have instant access. We have been able to replicate the issue using just SQL server on a W2K workstation and accessing from another W2K workstation. Again data access is way slow unless the account ...Show All

• SQL Server insufficent system memory

  Running a large transaction that runs successfully in SQL 2000 in a couple of minutes but running on another system with SQL 2005 after 4 hours it failed with error “ there is insufficient system memory to run this query” Both systems are running a GIG of memory with 1 instance each and nothing else running. 1 Gig of memory for SQL 2005 seems to be way underpowered as crazy at that might seem. Is the only answer to add more memory or are there settings I can adjust to avoid SQL 2005 from being such a hog Thank you in advanced, Pauly C ...Show All

• Visual Studio 2008 (Pre-release) Do you plan some editable ListView (DataGrid) WPF control?

  Do you plan some editable ListView (DataGrid) WPF control It is my understanding that the set of controls that will ship in v1 are complete in the current beta/ctp. There are control vendors working on such things, and you can get most of the way there with the existing controls. Look at the ATC Blog for some good examples on how to combine the current controls to produce a more complete data presentation result. For a full database editing experience you will need a third party control, or need to do some coding on your own. ...Show All

• Visual Basic Custom CType operator not being called

  This code defines a custom CType operator that converts Integer to TestNumber. This works great when converting from Integer to TestNumber. But an InvalidCastException occurs when converting from Object of type Integer to TestNumber. The online help for CType function implies that this call should work. "If the conversion is undefined, an InvalidCastException occurs. This can happen, for example, if expression is of type Object and its run-time type has no conversion to typename ." But because of the custom CType operator, there *is* a conversion from the run-time type (Integer) to typename (TestNumber). This problem is causing big headaches in my app. It happens on both VS 2005 and VS 2005 SP1. This seems like a CType bug ...Show All
