• Visual C# Access A Treeview From Another Form

  Hi, i need to know how i can add a node to a treeview that is on a different form. You can do so in the constructor for the newly created form. For example, overload the constructor of the new form to take an extra parameter which will be a treenode. So if the new form is Form2 then you would have: Form2(TreeNode tNode) { ... } When you create Form2 from the old form you just pass that node in: newForm Form2 = new Form2(node); This might not make much sense of you do not have an understanding of object oriented programming, and referencing variables in C-centric languages [In c# class objects are pass by reference and struct objects are passed by value]. ...Show All

• SQL Server Data retrieval is much slower in RS than in management studio

  A call to a stored procedure completes in 13 seconds when ran from within SQL Server Management Studio. A report whose data source uses the same stored procedure can take as long as 10 minutes to run. The same parameter values are used in both the direct call and the report. The execution log says almost all of that time is spent on data retrieval. How could that be What might be the cause I'll give it a try. However, looking at the Parameters column from the ExecutionLog table confirms that the values are the same. The report has the same parameters as the stored proc and simply passes the its parameter values along to the stored proc. ...Show All

• Smart Device Development How to Merge *.reg File From Code

  Hello, Reg files usually are merged automatically during Cold Boot. Is there a way of merging a reg file from code (Something different than reading the file, parsing it and manually calling Reg functions from API.) The only thing I was able to find out about the issue was information about existance of RegMerge.dll. Thanks, Artur Good point. However, if you actually choose that item it would ask you "If you'd like to add it to registry" not if you'd like to "merge it". Menu in regedit states "Import". Another point would be what not everybody’s using explorer to import/merge/add registry files, some prefer command line or Start/Regedit/Import and might never see ...Show All

• Software Development for Windows Vista PrintFilterPipelineSvc.exe getting closed.

  Hi, My print driver is giving the following problem in RC1 WDK and VISTA. The print filter pipeline ( PrintFilterPipelineSvc.exe) is getting closed. Exception. Print Filter Pipeline Host stopped working and is closed. It may be because of DEP (Data execution prevention), which cannot be disabled for ( PrintFilterPipelineSvc.exe ) in VISTA OS. I am not able to find the exact cause of this problem, because the printdriver was working properly earlier before RC1. When trying to print an image in PhotoGallery I am getting the following error dialog "Windows can't find a print provider for this printer. You may need to re-install the printer and try again." Please help. Regards, Lalit. It looks like you are using the SimplePipelin ...Show All

• SQL Server Dependency Network Graph Question

  I have some problems in understanding the dependency network graph which is built in the association rules algorithm. My questions are: 1) Assuming an arrow goes from Node A to Node B ( A --> B), is Node A dependent from Node B or is Node B dependent from Node A 2) Are only rules used with one element on each side of the rule (itemset size = 2) or is the graph also influenced by rules with more elements 3) it is said that the slider on the left side is related to the probability of the rules. when viewing my rules table I don't understand why some rules are viewable later then other ones because they have the same probability. Is there another parameter influencing this slider Which one I would be grateful for your help! Regards, David ...Show All

• .NET Development Custom (inherited) ConfigurationSection saved using Configuration.Save() Problem! Please Help!

  I have taken a common Generic ConfigurationSection that was posted on some public forums a while back and modified it to be a fully generic ConfigurationSection for use on any generic object type. The purpose is to be able to write a Configuration Object that uses Xml Serialization attributes for how to write the XML configuration section. Well, everything works excellent, however, there is a problem. ObjectConfigurationSection and ConfigurationObject classes are defined in a shared assembly that is registered in the GAC and re-used. This assembly has a high likelihood of being upgraded over time, but I DO NOT want to have to upgrade the product. Since GAC assembly references in the <configSections><section> type attribute ...Show All

• .NET Development vfpoledb & cdx > dbf problems

  When I try to open, (i.e. join), .dbf files using vfpoledb and there are .cdx files present in the free table directory. It will not work. I get a prompt for a 'convcpp.prg'. This must be a run-time expression compiler or something. I am using C# over FoxPro and VFP tables. When I copy the .dbf and .fpt files to another directory, then I have no problem with the vfpoledb data access. I don't get these prompts with the ODBC drivers. Is there a way to specify in a connection string for vfpoledb to ignore .cdx files A read-only scenario for my vfpoledb connection would suffice for now... and what are those prompts for .prg I've never used FoxPro or VFP. My problems show when I try to query with joins, which is what the .cdx files concern t ...Show All

• Visual C++ Why does VS rebuild all projects again when we start to debug?

  Hello everyone, We have about 10 projects in our solution and obviously the rebuild of the solution takes some time. The problem I have with Visual Studio is that if I make a change to a project file(code change) rebuild the solution and then say "Start Debug" the whole solution rebuilds again for the second time even though it was built a second ago and no change has been made to the project files. Why does Visual Studio do this I would like VS to rebuild the solution on "Start Debug" only if changes have been made to the project files since the last rebuild. Is this a simple setting change in the VS or is there a reason it has to rebuild everytime on debug Any suggestions will be greatly appreciated. Thank ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How do I know if a resource is managed or not?

  I'm following the recommended pattern on Loading Resources in the XNA Framework . I know that if I do something like the following: vertexBuffer = new VertexBuffer(device, typeof(VertexPositionTexture), vpt.Length, ResourceUsage.WriteOnly, ResourcePool.Managed ); Then that is a managed resource. But what about the following resources Are they managed or not How do I tell for resources where you don't specify a ResourcePool effect = new Effect(device, compiledEffect.GetShaderCode(), CompilerOptions.None, null); texture = Texture.FromFile(device, "mytex.png"); vertexDeclaration = new VertexDeclaration(Device, VertexPositionTexture.VertexElements); Also, just to make sure, I never have to call .Dispose() on a managed resour ...Show All
