• Visual C# Q: Working with Graphics object

  Hello everybody. I have a text file with the paths of all images I want to use. What I want to achieve is to read this text file line by line, create a bitmap using the path, resize the bitmap to a custom size and place this so called thumbnail into a graphics object. The graphics has to write on a bitmap of custom size. What I don't know is how to place all the thumbnails so whenever they reach the end of the width to go on the next row. I hope you understand what I mean. g.DrawImage (bmpFromTXT, (i%10) * 20, (i / 10) * 20 , regionWidth, regionHeight); i tried this but does not seem to work. It just displays them half the way of the bitmap to write on You want to Create Thumbnails of Images on a single Bitmap or on some Surface li ...Show All

• Visual Studio Team System Load test - "Avg. Connection Wait Time" counter

  Hi there, Do I need the "Avg. Connection Wait Time" counter on LoadTest:Request when executing a load test using one machine (Computer). This counter is added by default to the Load test, if yes how can I locate the Dependent Computer property, as this is blank I'm not sure why you're wanting to delete this counter, but I'm guessing that you're seeing a threshold violation regarding the "Avg. Connection Wait Time" counter. By default, a threshold rule is applied to the "Ave Connection Wait Time" to alert you that you may want to increase you connection pool size or change to connection per user. If you want to change the threshold rule, you can find the threshold rule u ...Show All

• SQL Server Reducing failover time

  Hi All, Is it possible to reduce the automatic failover time on MS SQL 2005 It seems to take around a minute on my servers. Thanks for your help.

• .NET Development ODBC or OLEDB

  Hi, We will be starting a new application development project shortly with various front ends (web, smart client etc) and trying to find out if OLEDB is better than ODBC to connect to our data sources. We need to connect to Oracle, MS SQLServer and Ingres. (May be others i.e. MySql in the future) I have read through a number of msdn documents but cannot get a difinitive answer, can anyone point me to a page where microsoft actually says OLEDB is better than ODBC. Regards Chris - ODBC is a set of system API function calls. OLEDB is a set of COM objects - I don;t say ODBC deprecated but MS provides more important data services with OLEDB - SQL Server and Oracle providers are faster than their ODBC drive ...Show All

• Software Development for Windows Vista Reasoning behind CardSpace's secure desktop

  The CardSpace's secure desktop is displayed in order to submit your card. I don't fully understand the reasoning behind the decision to disallow interaction with the desktop while selecting and submitting a card. Can anyone explain this What I'm most interesting in, is the fact that there is a Firefox Identity Selector plug in available at http://www.xmldap.org/ . This plugin, being based on Java, does not lock up the desktop. So, given that there may be valid reasons for having a secure desktop for identity selection, would that mean that any non-Microsoft identity selection solution will be 'sub-optimal' One of the advantages of building an identity selector for a particular Operating System is ...Show All

• Visual Studio Visual Studio .net 2003 crashes if I bind with Clearcase 2003.06.00

  I have installed the Clearcase with VS.net 2003. I loaded the solution(basically C++ projects) from the SCC. It asked for the binding information. I bound the SCC information and it displays as MSClearcase. However as I wanted to use Clearcase tools and integration I checked the Clearcase base and UCM tools in the Tools->Customise->toolbox. After this if I restart the VS .net IDE, it crashes. But if I uncheck the Clearcase tools it seems to be okay. Also on another developers workstation, the IDE crashes after loading the solution from SCC. Anybody has any idea what is the problem Sri, Rational owns and services the MSSCCI provider that integrates with Visual Studio to provide source con ...Show All

• Visual C++ Help: Rich Edit Control Border Not Repainting

  I recently wrote a Windows interface for a command line program, which is the first Windows programming I’ve done. Unfortunately I have an issue where the frame of a sub-classed rich edit control is not being redrawn when I drag a window over it. Here is a screenshot of how the border of my command ends up after I drag a window over it: http://i15.tinypic.com/4gi50rt.jpg I was hoping somebody might be able to suggest why this is happening. Here is the code related to creating the rich edit control box: HWND hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, RICHEDIT_CLASS, "", WS_CHILD | WS_VISIBLE, 0, 0, 0, 0, hWnd, HMENU(IDC_COMMAND_ED ...Show All

• SQL Server Wondering the best way to do this

  Here is the problem that I am trying to solve. We currently have a mail order manager application that we use. We have several vendors that we have to initiate purchase orders with, and this is currently done manually. I am converting it to do the purchase orders through a webservice, but I would like this to complete in real time. I figured the best way to do this would be to initiate a trigger when the particular table has a record inserted. This insert triggers a script, passing the order number and verifies if a purchase order needs to be initiated based on what was ordered. If it does, it contacts the webservice, gets the appropriate data, then updates the appropriate tables with the new data, all through the script. I have ...Show All

• Visual Studio 2008 (Pre-release) VB 9: Order By bug?

  Can anyone explain to me why Order By works fine while selecting the whole object: Dim data2 = From c In db.Cities _ Select c _ Order By c.Name But doesn't work when selecting only one property Dim data = From c In db.Cities _ Select c.Name _ Order By c.Name error BC32050: Type parameter 'K' for 'Public Shared Function OrderBy(Of T, K)(keySelector As System.Query.Func(Of T, K)) As System.Query.OrderedSequence(Of T)' cannot be inferred. The key here is the order in which the result sets are evaluated. In the VB case, Select c.Name creates a List(Of String) with the name of the string property as "Name". Thus, when you get to the Order By clause, it does not know about c In db.C ...Show All

• SQL Server Adventure works databases

  I am new to Analysis Services. In the adventureworks sample, we have the oltp database (AdventureWorks), the datawarehouse (AdventureWorksDW) and the cube ( Adventure Works DW). I am a little lost here. I thought the SSIS package updated the cube directly from the OLTP database. Looks like the datawarehouse is used to convert the OLTP to a star schema and *then* the cube is loaded. Could you please explain. Thanks! The datawarehouse (DW) is an OLAP multidimensional database that uses data from the OLTP relational database to create cubes, dimensions and so on. Whether the data in cubes is being updated automatically from the OLTP database depends on the settings, specifically the stora ...Show All
