• .NET Development .NET 1.1 Process class - peculiar/problematic behavior

  Hi, I am executing a console application using Process class using .NET 1.1 with SP1.   It has been working fine until we encountered a particular Windows XP SP2 machine - let's call it machine X.   On this machine, the newly spawn process simply returns with return code -1 (i.e., it's an error), and it does not generate any output to standard error or standard output - most likely it couldn't even have gotten started properly. The console application being spawn is a third-party application for which I do not have the source nor extensive documentation so I can't tell what exactly about this machine X that it doesn't like.  Without the source, attaching a debugger and stepping through is not an opt ...Show All

• .NET Development Marshalling structures with variable-length inline strings

  Greetings, I'm having trouble solving a pinvoke marshalling challenge in C#. I need to call an unmanaged API function which expects a structure containing a variable length inline string. Here's the unmanaged function prototype (from MSDN): BOOL SetupDiGetDeviceInterfaceDetail ( HDEVINFO DeviceInfoSet, PSP_DEVICE_INTERFACE_DATA DetailInterfaceData, PSP_DEVICE_INTERFACE_DETAIL_DATA DeviceInterfaceDetailData, DWORD DeviceInterfaceDetailDataSize, PDWORD RequiredSize, PSP_DEVINFO_DATA DeviceInfoData); The troublesome guy is the third argument, DeviceInterfaceDetailData .

• Visual Basic VB2005 Express Setup EXE - Deplyment - Reloaded

  I do have another question. Sorry for being a pest. In VB6, there is a deployment tool that creates a setup.exe program. That utility creates a setup.exe along with a *.cab file. I like to use this system to create a ZIP file so I can distribute my programs from my web site. I cannot seem to locate anything like this in VB2005 Express. I did find something called "Publish To Web", but I use Yahoo! as my web host & VB2005 Express cannot post to there because of something about FrontPage... Any ideas Thanks in advance, -Ron VB express does not have a setup project template. I would use publish my application to a folder on my local hard drive.

• .NET Development Problem With File Dates Created During Daylight Savings Time

  I am using VB .NET 2.0 with Visual Studio 2005. I have a VB program which keeps adjusting the file dates when the files are considered to have been created or written during a Day Light Savings period. By this I mean when I read the IsDayLightSavingsTime property of a file date and it returns TRUE. For example, if I read a file that was last modified on 5/6/2006 at 8:00 a.m., my VB program keeps adding one hour to the time so it ends up reading as 5/6/2006 9:00 a.m. How can I stop this I need my file dates to match what is shown in the explorer window when you browse your files. This problem does not happen when the IsDAyLightSavingsTime property reads as FALSE. Below is a snipet of how I am getting the LastWriteTime of the files: ...Show All

• SQL Server Specify excel sheet as a configuration property.

  Hi, I'm just starting with SSIS and want to create a reusable package which imports from an excel file which can be specified at runtime. I can expose the filename of the excel file as part of the connectionString property but the sheet is the openrowset property which is a custom property and therefore isn't exposed as part of the external configuration. Does this make sense Is there an easy way to specify the sheet to import at run time Regards, Anthony. Rafael, Thanks for taking the time to answer. I think I'm missing something basic though, as I can't see "SQL Command from Variable" in either my excel source data task or my excel connection manager. Regards, Anthony. ...Show All

• SQL Server Aggregation functions in Calculated Measures displays wrong values.

  Hi, I think this calculated measure implementation is making me absent minded, so if this seems like a silly question, please ignore my behaviour but do answer to my post :-) I will ask this question with a sample data: consider that the cube consists of School Children's names as the first dimension (school_children) and date(jan, feb....) as the second dimension. the measure (M) is the 'exam scores' of the school children. jan feb mar school_children M M M ----------------------- tony 50 20 40 bony 10 40 40 mony 60 60 70 Now when i add a calculated measure where I want to display the avg marks of each. so in the calculated measures formula I add: Avg([Measures].[M]).
