• Windows Forms How to cancel form load, if error is detected during constructor execution or load event

  I am looking for a way to stop the form from loading if problem occured during load (constructor/Load event). If I use this.CLose I get an error message stating you cannot close an object that has not been created. Any suggestions would be appreciated. Thanks. Two thoughts: 1.) If this is the only form in your app, or if it's the  ...Show All

• Visual Studio Express Editions Object Reference Problem, Why doesn't this work?

  Hello All, I am really stuck here and I could use some help in figuring out why this code does not work in .Net. I am converting/rewriting a VB6 app. The VB6 code does what it is supposed to do. The .Net code is syntatically correct as far as I can see but does not function as expected. What is supposed to be happening is that clsApp.Mainform is supposed to be getting set to frmMain which is the central form of the application, thus allowing me to manipulate frmMain from within my application by accessing clsApp.Mainform. What happens instead is that clsApp.Mainform is set to a generic form object and does not have any reference to frmMai ...Show All

• Visual C# Where is vsvars32.bat ?

  Hi, I have installed VC# express 2005 final on 2 computers. On one, I can find vsvars32.bat in the Common7\Tools folder. This folder also contains a lot of other things. On the second machine the same folder Tools only contains a subfolder VDT. There is no vsvars32.bat and all the other stuff. I tried to repair/uninstall/reinstall but still the same.

• SQL Server The SQL Network Interface library was unable to register SPN. Error: 0x490

  I recently installed SQLExpress Beta 2 on WinXP. After power up and logon there is a substantial delay - minutes - sometimes maybe forever. In the event viewer I see: "The SQL Network Interface library was unable to register SPN. Error: 0x490" This is on my home network with two computers one using WinXP the other Win2000 configured as a workgroup. I say maybe forever because if I tire of the wait and hit system reset - after the reboot this delay does not occur. What can I do (beyond uninstalling SQLExpress - which does work to eliminate the delay) to stop this probem Hi KerryK, The message in the erro ...Show All

  I don't know how best to explain this but will try. In my SSRS 2005 report, i have one group in my table.  In that group, I have a field that for each company record in my dataset, this field value is repeated for each record. This is a transactions table so you'd expect several records in the dataset for each company..that's not the problem. example data from dataset: TransID     CompanyID      FeeGoal 1                1000               ...Show All

  Hi Pretty new to using VB 2005 Express. I would like to use a database with one row of initial data, which after a program has been used will then update that row of data on exit.

• Visual Studio msi installer with 1.1 build output?

  Hi all, I have just migrated to VS 2005 and I am very interested by the potential of the MSBee tool. I read the documentation carefully and I could reproduce the described scenario up to section 4.4 of the document. I could build successfully two .NET assemblies against the 1.1 framework: the first one was a 'Windows application' project, the second one was a 'Class library' project. In each case the msbuild utility created a folder named FX1_1 under the directory obj of the project directory. I choosed the option /p:Configuration=Release on the command line, and thus the build output was generated under a subfolder named Release . ...Show All

• .NET Development Is it possible to change the namespace of parts of a wse3wsdl.exe generated proxy?

  My web service uses typed DataSets quite a bit, and so the typed DataSet is part of the proxy file generated by the wse3wsdl.exe tool. The problem is that all the generated proxy code lives in one namespace. For most of the objects, this is fine, but for the DataSets, it doesn't make sense. Is there any web service attribute I can use that will change the namespace of certain classes in the proxy If not, this would be a very useful feature, as would the ability to output multiple files from the wsdl.exe/wse3wsdl.exe tool. Thanks, Erick I think that you can't do that with the tool, the solution that I ...Show All

• SQL Server How to handle multiple column conversions

  I have multiple columns in a table that I only want to convert if they are not null or of the proper type. I don't really want to redirect the whole row if one of the conversions fails, rather I would just not want to do the cast or set it to another value. In this scenario is it better to use a custom script or multiple tasks The multiple tasks seems like a lot of overhead for processing the same data. Just curious how others handle this scenario as it seems as though it has come up quite often on our current project Thanks for the assistance. -Krusty PS: Is it possible to embed evaluation statements along with conversion statements i ...Show All
