• SQL Server how scalable is service broker?

  I've heard the advice that a client application shouldn't use more than 10 concurrent SqlDependency objects. Does this suggestion apply to the ASP.NET layer Is there any reason that we couldn't have 100 SqlDependency objects running concurrently in the ASP.NET layer Service Broker is designed for extremely high scalability, supporting millions of services and dialogs. However your question is not about Service Broker, but about SqlDependency. If there are recommendations for the number of SqlDependency objects running concurrently those derive from the SqlDependency itself, not from the Service Broker. There are two main factors that limit the SqlDependency scalability: - in order to receive notifications, each appdomain posts one ...Show All

• Windows Forms Picture in DataGridView cell?

  Is there a way to put a picture or Button control in a DataGridView's cell Thanks in advance, Devin Actually, if what you mean is to add a column with images or button controls, that's possible using the DataGridViewButtonCloumn and DataGridViewImageColumn classes. Just create a new column/button column and then add it to the data grid view's Columns Collection. What language are you using ...Show All

• Software Development for Windows Vista ValuePattern setvalue on an edit box is not working

  When setvalue is done on an edit box, the value which needs to be set is displayed in the edit box, but the application is not able to recognise the set text, internally it is just seeing the blank field Moreover the Value pattern was supported by the edit box when seen from the UI Spy. At the end I have to fall back on using the SendKeys Application is Visual Studio 2005 and framework is UIA 3.0 for .NET ~JK Thanks for the suggestion This doesn't work even if i set the focus on other controls. The automation code does do other operations after setting the values, so the focus change has happened, and in spite of that the value is not read by the application ~JK ...Show All

• Visual Studio How can I add existed DataBase scheme to my DSL as inpuit?

  CONNECTION TO REAL DATA or SCHEMES FRAMEWORKS I want to make some generation from DB to C# classes with two tasks: 1. use DSL code or some framework - to read DB scheme and generate some classes or triggers and subscript it to compilers or SQL server. 2. incorporating some logics created in DSL to this process. Once DSL is code template engine it is expectable that it can provide some PRODUCTION input data or schemes for taking part in generation: for sample CodeSmith provides DB scheme or custom schemes for else sources and application generation become truly PRODUCTION relation and easy as breesy. does DSL can provide such a really well features _________________ EASY OF USE: I took CodeSmith yesterday first time, take 4 h ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Earlier shader models in D3D10

  Are there any plans to support shader models earlier than 4.0 in D3D10 -- Tim Preston The compiler has a compatibility mode to enable easier compilation of 2_* and 3_0 content, but there are no plans to add support to D3D10 for lower models. Recompiling for the 4_0 model is the supported mechanism. The D3DX9 compiler is going to be updated to be able to handle the new syntax features. That way you can have a single HLSL or FX file that works on both D3D9 and D3D10. Craig Peeper Microsoft, Direct3D ...Show All

• Visual C# An array of *different* classes

  Is it possible, perhaps using pointers, to have an array of different classes I'm writing a text processing app and I'll have an abstract class 'word', and two child classes which inherit 'word'; 'text' and 'number' which will both behave differently. I want to be able to represent a sentence of numbers and words in a single array (or perhaps a linked list), but have the numbers and words represented by objects which do different things. While I'm writing, where should I go to get information on working with ADO.NET's DataSets The MSDN library's information is quite difficult for me to digest. Thanks for the help, Kestas Different classes are ok, but probably best is to have them all in the same class t ...Show All

• Software Development for Windows Vista Is the method "WorkflowInstance.Load" required?

  Hello, Do I need to call the method " Load " of the WorkflowInstance class myself, or will it automatically be called when I use the method " RunWorkflow(instanceID) " of the ManualWorkflowSchedulerService I tried both possibilities and did not see any difference in result... Also, I cannot find any documentation about this topic. The only information I found was WHAT the method " Load " does, but not WHEN it's needed. Thank you for you time! Most likely what you're seeing is that the instance, if it isn't already in memory, is being loaded when the message is delivered to it (we have to have an instance in memory to deliver messages to it). It's already in memory s ...Show All

• Visual FoxPro VFP7 COM+ object and ASP.Net 2.0 on IIS6 - Interop issue

  Hi,I wonder has anyone managed to get his/her VFP7 COM+ object run on ASP.Net 2.0 on IIS6 1. I compiled the object using MTDLL and deployed into my SBS2003. 2. I think this shouldn't be a security problem as I didn't manage to get it run even I have set the IIS6 worker to Local System. 3. The COM+ object has actually initialised. Codes in INIT method has actually run (I put CREATE TABLE ..... in the INIT method, and check if the table is created later), but when come to calling a method from ASP.Net, I hit an error. 4. Tried many possibilities, but no luck. I have also followed the example from Craig, got the same issue. 5. The same VFP7 class (but complied as EXE and configured as DCOM) was running fine on IIS5 ASP2.0 on Windows 2000 Ser ...Show All

• Visual C++ Can't exclude items from file open common dialog

  This is from MSDN: The CDN_INCLUDEITEM notification message is sent by an Open or Save As dialog box to determine whether the dialog box should display an item in a shell folder's item list. When the user opens a folder, the dialog box sends a CDN_INCLUDEITEM notification for each item in the folder. The dialog box sends this notification only if the OFN_ENABLEINCLUDENOTIFY flag was set when the dialog box was created. If the OFNHookProc hook procedure returns zero, the dialog box excludes the item from the list of items. To include the item, return a nonzero value from the hook procedure. Remarks The dialog box always includes items that have both the SFGAO_FILESYSTEM and SFGAO_FILESYSANCESTOR attributes, regardles ...Show All

• Windows Live Developer Forums Restrict VE Map scroll

  My client has just asked me this – and I am not sure if it can be done My client wants to limit the outer edge of the map scroll to an area around the UK. (to stop users VE’ing their holiday destinations during work hours) Any suggestions IF this can be done Yes but that is good if you are in on a particular zoom, however lets say you are at county level and start panning across the uk, when you reach the boundary I would actually like to un-pan the the last move. Is this possible like reversing the last view change rather than setting map to required centre. I am guessing that the only way would be to record the center of the map prior to the pan and if it goes out of boundary then move ba ...Show All
