• Software Development for Windows Vista Workflow & Business Logic and Data Access Layer Best Practices

  I am currently developing an purchasing application that has an assembly exposing its data access layer. Objects in the data access layer implement standard C.R.U.D functionality via ORM. The objects also exposes datasets. 1. Can anyone tell me how best to implement WWF and DAL interaction. Do I need to create custom activities such as GetOrders, CreateOrders etc. (exactly what's exposed in the DAL already) 2. Do I create 4 custom activites, one for each CRUD function, and pass a BusinessObject or Dataset back and forth to the Workflow. Any information on what are the best practices here are very welcome. Thanks, Martin I guess it's ...Show All

• Visual C++ Win32 File Writing Problem

  Hi all, I want to write a large amount of data (char data[7000][2]) to a file and I have to write those characters one by one,  I tried to use Win32 WriteRile() fuction to write them. Ofcourse it can write the data correctly, but it is very inefficient and I have to wait a long while. I know some other platform (symbian) has APIs like WriteInt8() or WriteInt16() to handle this kind of problem and these fuctions are very efficient. I think calling WriteFile() 14000 times is a very heavy task. So, are there any other Win32 functions can do this kind of jobs Thanks. The easies ...Show All

• Visual Studio 2008 (Pre-release) Mixed credentials: Username & Certificate

  Greetings, Our services will be exposed on the Internet. Only specific partners applications should be able to have access to them. At the same time, the partners applications users will need to be authenticated & authorized by our services. We will use role-based security to authorize them. The reason why we need a double validation using a certificate for each application is because we don't want anybody on the internet to be able to query those services directly (that includes our users having usr/pwd credentials who could try to pull the services content from their own app). We want to make sure only "known" applications ...Show All

• Visual Basic MultiLine ToolTips

  Somewhere in the Help I happened to notice that ToolTips can be customized to show multiline text. Now, when I need it, I can't find the appropriate help text. How can this be done Thanks for the answers! It was just too obvious for me to see. Now I have implemented a version that matches my needs; I just set the controls ToolTipText = "This is a" & Environment.NewLine & "multiline tooltip" ...Show All

• Visual Studio Team System TF30162: Task "WITs" from Group "WorkItemTracking" failed

  This is with Beta3 on a real 2003 Standard Server SP1. Setup worked without a problem. I did change the name of the three accounts but they all work fine. I cannot create a project with a user account that's in the domain admin group. However I can create a project with the <setup> account logged on on the server directly. Thinking it's a SQL permission kinda thing, I gave the domain account all the same permissions as the <service> account, but that still did not work. I tried the deletion of the cache directory, but that did not make a difference. Can someone give me any hints how to go on with this. Peter ...Show All

• Visual Studio 2008 (Pre-release) WPF apps slow for some reason

  Everything is slow for some reason. I tried Max, and that ran decently (aside some weirdness I'll explain below), but I try running some of the sample code and other stuff I compile on Visual Studio, and it's unbelievably slow. I tried the samples here  on XamlPad... I can click on a button at a rate of about 2-3 times a second, and my CPU usage will jolt up to 100%. Most other sample applications run just as slow. Max runs okay, except that it takes about 40% of my CPU time even when it's minimized. By the way, is there something I can do about text being blurry Here are some of my machine specs: Pentium 4c 2.4ghz HT 1gb DDR 400 dual ...Show All

• SQL Server Chart Labels at an angle??

  Hi, I have created a report with bar chart but the labels are too long and often go into next line. Is there any way to specify text orientation for labels of a bar chart I would like to show the chart labels at an angle. Is it possible Any help will be appreciated! This depends on which labels you are referring to. If you are referring to data point labels, then yes, it is possible to specifiy an angle. However, if you are referring to the labels on one of the axes, then no, it is not possible at this time to specify an angle. These labels are positioned automatically. The ability to manually set the angle for axis labe ...Show All
