• Visual Basic Disabled Panel or GroupBox

  Hello. I'm working on a project right now. I placed my controls (textboxes, buttons, etc) in a panel or groupbox, and disabled these containers by default so that users cannot play with these controls unless it is in edit mode or adding a new record. My problem is when these containers are disabled, background and forecolors of textboxes,comboboxes, etc are grayed which do not give good presentation of data or impression to users as far as font color is concerned. Such color is hardly read. So, how could I solve this problem Should i enable these containers always and set readonly to True to these controls, which I beli ...Show All

• Visual C# Generic Interface Casting

  Hi All, I've got a class that wraps other objects. In .net 1.1 I used an interface like: public interface IMyWrapper{ object Data{get;} } In .net 2.0 I thought I would try something like: public interface IMyWrapper<T>{ T Data{get;} } Now consider the use of this interface in a method such as: public void MyMethod(object o){ //in 1.1 if (o is IMyWrapper){ //Do something else with the wrapped data AnotherMethod( (o as IMyWrapper).Data) } //in 2.0 if ( o.GetType().GetGenericTypeDefinition() == typeof(IMyWrapper<>) ) { //Do something with the wrapped data AnotherMethod( (o ...Show All

• Visual Studio Tooltip not showing up in ReportViewer

  I have a report that displays an image in a table column that allows the user to drilldown into a detail report. The image has a tooltip associated with it. When I view the report in Report Manager it displays the tooltip. When I display the report in a ReportViewer control (in remote mode pointing at the same report) the tooltip does not display. Is this expected behaviour Report Manager is using the ReportViewer control, so there should be no difference. Can you post a simple repro rdl ...Show All

• Windows Forms Toolstripmanager and Visibility

  First, please forgive me for making a second independent post on the same topic. I have new information and my sense is that if I reply to my own posting the automatic procedures at MS won't pop it up for action. (Correct me if i'm wrong and there is a better way to handle this.) Second, please forgive the bright red print below. It separates the new stuff from my original post. I wrote: It's clear that loading and saving settings with toolstripmanager works great for strip position on the window and for item position with in the strip. It does not seem to track visibility / availability. Is my observation correct If so, then li ...Show All

• .NET Development How do I retrieve new primary keys after inserts?

  Hi, I am relatively new at ADO 2.0, so please forgive the simple question. I add some rows to my datatable in memory, but without trying to assign primary keys in the rowid column. In the datatable, the rowid column is null for all the new rows that I add. Eventually, I use a dataAdapter.Update(table) call to update the database, which is successfully updated. But now the problem arises... I don't know how---for those new rows that were just inserted into the database---to read the new primary keys (generated by the database) back into the correct rows in my datatable (using a dataAdaper if possible, using plain SQL if not). I don't wa ...Show All

• Windows Forms DataGridView Edit Problem..

  Hello, I have a DataGridView setup with a DataAdapter.  There are a few fields on a couple of rows that I update programatically which causes the DataAdapter to want to update the data in the database every time I run the DataAdapter's Update method.  Is there anyway to set the status of the row to NOT update the database (at least until a user edits something) Thank you -Adam Plocher No - Calling the DataAdapters update method will cause changes to be pushed to the database regardless of how the changes are done. There might be a way to inspect the diffs contained in the DataView or DataAdapter ...Show All

• Smart Device Development Setting up the Correct ATL Include and Lib paths after eVC4.0 project port to VS2005

  Hi I ported an application that compiled and linked fine in eVC4.0 to VS 2005. When I compile the project in VS 2005 I get the following linker error: LNK2019: unresolved external symbol VarBstrCat referenced in function "public: long __cdecl ATL::CComBSTR::AppendBSTR(wchar_t *)" ( AppendBSTR@CComBSTR@ATL@@QAAJPA_W@Z) In looking into this I see that the include file used for ATL is the main Win32 one and not the SmartPhone 2003 SDK one. I know I can include this in the Tools->Options->Directories stuff but if I do this this will have an overall effect on all project (non Smart Device ones included). If there an ea ...Show All
