• Visual C# Error accessing win32, VC++ 2005 dll in C# 2005

  I'm trying to call a win32 library function that I have authored in VC++ 2005 from C# 2005. I get an exception from the C# program that reads "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I cannot step into the function in the dll for some unknown reason, so I have no idea which parameter is causing the problem. Here's the function declaration in VC++ PEAKDETECT_API void fnPeakDetect( double *darrInputArray, int iElements, double dThreshold, int iWidth, int iPolarity, int iInitialize, int iEndOfData, int *iNumPeaks, double *darrPeakLocations, doubl ...Show All

• Visual Studio Team System no coverage result for website

  How can I get code coverage results against my website in my unit test projects I tried adding the website to my test solution and add it to test run config to be instrumented. But after doing that, my test case can't work fine and I'll notice the weird error message: Failed to connect to an IPC Port: The system cannot find the file specified. Anybody has any idea Hello Shu, Unfortunately, I am not sure that there is a workaround for the Beta2 problem, you are experiencing. I would recommend that you upgrade to Release candidate version. Just be sure that you fully remove the Beta2 before that (there is a t ...Show All

• .NET Development Use .net serialization or a custon soultion?

  Hi, Basically, I need to clone objects to remote processes. Now it's not that simple... I want to decide per remote client which members are to be serialized. Some of the data must remain hidden for security reasons, and the extent of the data hiding is dynamically computed at runtime and may change per object per client over time. In some cases only a part of a  class might have changed. I'd want to serialize only the affected data to perserve bandwidth, CPU etc. Performance is an issue! and it seems to me that serializing/deserializing via string tags e.g. the "i" in info.AddValue("i", n1); might not be very efficient. ...Show All

  I'm wanting to create a sort of task manager type application where the software displays the running processes, associated program and the amount of time the program has been running for.

• SQL Server Loop through each record and then each field within each record

• Windows Forms would you deploy a smart client that contained a non-local database connString in the appConfig

  hiya, I'm creating a winforms app that will run on a LAN. The user is keen to see constant demos of progress.Logistically, it's difficult to meet up as often as we'd like. I was potentially thinking of deploying the app to a webserver as a smartClient. However, the app contains a connection string to my dev database on my dev webserver. I am obviously concerned that the user might be able to get access to the connString that resides in the app.config file of the smartClient app.. Any comments appreciated. many thanks, yogi       ...Show All

• SQL Server Random access in a result set

  I use an SQL task to produce a result set which I store in a package variable. It works fine to access the result set in a script task by first casting it to a ADODB.Recordset, and then enumerating it and accessing the rows in the given order. But is there a simple and clean way to randomly access the result set  In other words to repeatedly select a random row from it One thought I had was to convert the result set to some sort of array which can be randomly indexed. But I didn't find out how... I'm not interested in creating an array by looping through the whole result set and inserting the row ...Show All

• Visual Studio Charts are not rendered in CR for VS2005 Beta2 Version

  After much newsgroup searching, I was able to make CR work on my web server. However the charts (images) inside the reports do not show up.

Hence 2 questions: 1. How can I specify the domain name for the URLs or tell it to use relative path 2. Where can I find CrystalImageHandler.aspx I searched my entire HD and could not find it. Thank you. Well nice said, but for me my client is still. coz on the dev platform all ok. wh ...Show All

• .NET Development .NET Framework 2.0 question

  I appologize in advance if some of my  questions to the forum is a little out of place. I am not a programmer or developer, just a gamer, system builder, and network administrator of a home network. After installing .NET Framework 2.0, Direct X9.0c's Diagnostic shows that one of the two system.dll files is missing. The one that is listed belongs to 1.1, so logic dictates that it is the one for 2.0 that is missing. However it is in the .NET 2.0 folder! Some other symptoms are that logging into .NET sites must be done manually (being signed in with MSN Messenger does no good), and Auto-Scroll function for IntelliPoint 5.2 does no ...Show All
