• Windows Forms Binding a MonthCalendar Control to a DataTable of 'selected' dates

  I need to bind a MonthCalendar control to a DataTable which contains dates that represent 'OffDays' i.e. no work. I am hoping to do something like, a user can select (or un-selected) a date in the calendar and that will add or remove records from the DataTable. I notice that there are methods of the MonthCalendar control to Add or Remove bolded dates and that seems like it would work, except I can't DataBind that. Bolded Dates aren't a requirement, just something to visually distinguish the 'OffDays'. I don't develop WinForms much and I don't know much about the MonthCalendar. If anyone has ideas to simple databind here, it'd be GRE ...Show All

• Windows Forms DataGridView GetFirstRow() problems

  Hi all I'm using the GetFirstRow(DataGridViewElementStates::Displayed) function to work out which the first row displayed on the list at the current time. There are two problems with this though. First is that the docs say that it is meant to be for internal use of the framework rather than being used by plebs like myself. The second problem is that if the DataGridView isn't actually visible, the function returns -1. Not surprising I guess since none of the rows are actually visible. But I still need to do things to this first row even if its not currently visible. Does anyone know a better way to get this first displayed row ...Show All

• SQL Server [rsDuplicateScopeName] More than one data set, data region, or grouping in the report has the name ‘CustomerName’. Data set, da

  I have one rdl with about 7 rectangle regions, each rectangle I dragged a table inside. When I try to render myreport I get [rsDuplicateScopeName] More than one data set, data region, or grouping in the report has the name ‘CustomerName’. Data set, data region, and grouping names must be unique within a report. Furthermore, I don't see anything in the Rectangle's "Data Region" dropdown to associate my tables to it. Also, once I do successfully assign a rectangle to a Data Region (a table) successfully, I assume i can then reference fields from other DataRegions / Rectangles in other tables such as doing a summary table at the en ...Show All

• Software Development for Windows Vista Passing parameters into the workflow.

  Hi, I'm very new to workflow, and need help... I created a workflow library that has a custom workflow action developed. Then I used a winapp to test the workflow, in preparation to deploy the custom action into office 12.

The problem is, I don't know how to pass parameters into the workflow. I have the workflow book, but I can't really make sense to what is written the codes are in snippets.

• Visual C++ What will cause AfxGetModuleState() return different values during DLL initialization?

  My application has over 100 Dlls. During startup, many resources failed to be found. I finally find out this is because AfxGetModuleState() returns different values in the CDynLinkLibrary's constructor, but I get no idea how can this happen. Anybody can help Thanks. Could it be a failure to use AFX_MANAGE_STATE(AfxGetStaticModuleState( )); on your DLL entry points This macro informs MFC that a DLL boundary has been crossed and needs to switch contextual information.
