• Visual Studio Crystal Reports: How to make Parameter fields optional

  Hi, Im a newbie at both C# and CR10. Im converting a M/F report to CR10, which actually contained 3 different layouts and selection criteria.

How do I make the CR parm fields optional thxs, drc i created a parm field that i loaded from a column w/ discrete/multiple values that the user may select from to filter the report. they should also be able to skip this drop down and include all rows. the dialog box requires an entry in this field. "Please enter a string". i tried modifying the record selection formula but w/no success. thxs for asking drc ...Show All

• Visual C# debugging: monitoring an object, conditional break

  In Visual C# 2005 is there a way to monitor an object I have a "global" object that is accessed (and modified) in a lot of places in my code. Is there a way to make the debugger break whenever a particular object is: accessed, and/or modified Without setting a breakpoint at each an every place in my code where access/modification of that object could potentially happen Richard Freytag wrote: You can set a conditional breakpoint by right-clicking on the "ball" representing a breakpoint in your code. A window will popup into which you can enter an expression. Same dialog will allow you to choose if the program halts at the breakpoint is the expression value changes or ...Show All

• Visual C++ 'System.TypeInitializationException' occurred!!

  Hello, does anyone know what's going on Somehow after I debug my project (without any error), when I run it, it comes with this error message. "An unhandled exception of type 'System.TypeInitializationException' occurred in Unknown Module." I have no problem if I release my project and run it but just debug. Any idea Thank you!!

• SQL Server unable to access "install windows components"

  I didn’t know where to put this so sorry if this is not the appropriate place. I am running Windows XP pro sp2 with visual studio 2005, ms sql server 2005, and a number of other applications. My problem is that I am not allowed to install new windows components(I want to install IIS). When I try to access from either control panel, add/remove programs, Install new windows components or directly from the winXP cd I get the following error in a pop-up form and I can only press "OK": "Another copy of Setup is already running. Complete the other Setup or restart Windows." I am not running the instance more than once. I do this as the first thing after a restart with the same result. When looking at the processes in the task manager I cant see ...Show All

• Software Development for Windows Vista Not getting drop down from design time validation error icon in rehosted designer

  I am not getting the drop down from the validation error icon in a rehosted designer. I have set WorkflowTheme .CurrentTheme.AmbientTheme.ShowConfigErrors = true ; in the WorkflowDesignerControl() constructor, so I get the icon but not the error message etc. Is there another step Yes - first you need to provide a MenuCommandService. Then you need some special handling code in the ShowContextMenu override - here is an example: public override void ShowContextMenu( CommandID menuID, int x, int y) { ICollection coll = this .GetCommandList(menuID.Guid); if (menuID == WorkflowMenuCommands .DesignerActionsMenu) { MenuCommand last = GetLast(coll); //Needed because of code i ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GPU "assembly" shader files

  I know how to load and compile C shader shource code into an ID3dXEffect interface. However, this mean I must have the source code with the program. What I want is to deliever the end user with only the precompiled "assembly" code of the effect, and not the source code. So, I would like to know how do I compile C shader source code into assembly, and load this assmebly into the D3DDevice. Also, how do I set global variables of the shader in this case Thanks in advance. Yes, you create the interface using D3DXCreateEffectCompiler(), then you use CompileEffect() to compile it into a buffer (ID3DXBuffer). Now you can store this data in an external file for actual effect creation later ...Show All

• Software Development for Windows Vista WCF activities, in a Winform host application and state machine WF.

  Hello everybody. I've created a workflow template in which there host application is a Winform app. This application runs a workflow using thread donation technique (using ManualWorkflowSchedulerService). Now, I've created some custom activities: one of them is used for navigation between one form and another in host application. Well, I did an Execute method override and, instead of invoking externaldataservice contract method (like the job done by a CallExternalMethod activity), I called directly the winform application classes for changing forms. Is it correct or is better to call CallExternalMethod activity Another question: I would like to create some custom activities to perform WCF service invocations, like sendmessage, receivemess ...Show All

• .NET Development Extra space on right side and bottom of a DataGridView

  Greetings, I'm trying to display the status of a set of "resource managers" (imagine a set of heaps). Each column of my display is a different manager, and the 'rows' are different sizes in each column, and represent the "allocated" or "free" status of that region in the manager. the following demo program shows my problem: I can't seem to get just one column in a DGV: the layout always includes some extra space at the right and bottom. I've made this area RED. I'm convinced its part of the DGV., and not part of the table or panel forms. I believe I need the DGV's to AutoSize, so that the columns of the table are full length. This allows the outer panel to do the scrolling of all columns in parallel. ...Show All
