• Visual Basic circular references between usercontrols and 'main' form in vb6->.net upgrade

  in upgrading from vb6 to vs2005 user controls are introducing a circular reference problem in the following way. In the vb6 solution, user controls could access methods in the 'Main Form' upon which the user controls are used. In VS2005, I create a separate Windows Control Library Project for each User Control. For composite controls I 'reference' any other controls as needed. However, there are controls which call methods/functions on the 'Main form' within a Windows Application project. That project includes the references to all the user controls ( which show up in the ToolBox.) Circular references have been introduced which didn't exist before. The Mainform references the User Control. The User Control calls MainForm methods. ...Show All

• .NET Development Problem: float +- operators give different results depending on computation order, flags, Win32/x64

  Hi, I have this small test program test.cpp: #include <iostream> using namespace std; int main() { cout.precision(8); float v1= -1.9513026f, v2= 0.31476471f, v3= 3.1415927f; cout << "v1-v2+v3= " << v1-v2+v3 << endl; cout << "v1+v3-v2= " << v1+v3-v2 << endl; return 0; } When I compile it (using Visual Studio 2005 SP1) with cl /EHsc test.cpp as a Win64 application (both on Windows XP x64 and Vista x64) and run it I get this result: v1-v2+v3= 0.87552547 v1+v3-v2= 0.87552536 So, depending on the order of computations I get different results. I know that float has only 6-7 significant digits, so some inaccuracy is to be expected (using double in stead of float gives ...Show All

• SQL Server Creating a Maintenance Plan via the Command Line

  Hello All, I've searched high and low for documentation on this to no avail. Basically my goal is to create a maintenance plan in SQLSERVER2005 via the command line. I need to create this plan in a way that it can be seen in the list of Maintenance Plans in the Management Studio Interface. I went into the SSIS designer and created my plan. I now have a DTSX file. I tried the dtutil.exe utility, however i never saw my maintenance plan in the list of plans. I ran dtutil.exe and did /FILE to /SQL but i don't see the plan listed or in a way a user could modify it, which is of the utmost importance to my clients. How do i get my file to turn into a real running Maintenance Plan that is seen in the list of Maintenance Plans via the ...Show All

• SQL Server Dimensions from Fact tables

  Most of the Fact tables I'm building seem to have a bunch of categorization type columns in addition to the numeric columns that naturally fit into the Fact tables. However it feels "wrong" to create dimensions from a Fact table, so instead I'm getting the ETL to split the tables: for every FactX table I get a DimXInfo table that has the non-numeric/non-key data. E.g. FactDeal includes dealID, price, quantity, product key, customer key (and other keys that relate to shared dimensions. DimDealInfo table includes dealID, ContractNumber, DealType Then in the SSAS cube DimDealInfo naturally forms a Dimension and FactDeal naturally forms a measure group. And you don't have to create a SSAS Dimension from the Fact table. Quest ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Tool for auto HLSL Generation?

  Are there any tools out there to enable the graphical building of a shader network, such as in Autodesk Maya's Hypershade tool or Softimage XSI's RenderTree tool, which can enable you to use a GUI to set up an object's basic material properties and then automatically generate the appropriate HLSL shader fragments needed to reproduce the material effect in your game without having to manually write HLSL files Certainly, if you want to create complex shader effects, you would need to be able to edit the HLSL or manually create new custom HLSL files, but for creating HLSL files to render basic, standard material properties, there really should be a graphical tool to take some of the work and difficulty out of it. Such a tool should allo ...Show All

• SQL Server Using variable in DataReader's SqlCommand text

  I'm attempting to configure a DataReader's SqlCommand text to use a package-level variable and I'm having trouble. I've read about using the "sql command from variable" option but although I see that during the configuration of Ole DB source, I don't see the same option for DataReader source. Viewing the properties of the DataReader and selecting the SqlCommand property does have button to configure the value but only displays a string value editor window. (I was hoping for the expression editor.) The configured connection to the DataReader uses the odbc Data Provider (under .Net providers). I'm connecting to mySql, if that matters. What I'm looking to do is to use a variable in the where clause of the DataReader's SqlComma ...Show All
