• Visual C# COM Interop - Best practices?

  Hi everyone :) I am currently developing some small tool which is being called by a Javascript script. So basically I am creating an ActiveX control. This already works but I am missing some sort of best practices approach. Currently I made my main class ComVisible so that all public methods will be exposed to the COM interface. Now I was wondering if there was a possibility to define a interface in the following way: public interface MyInterface { string getSomeString(); string getSomeOtherString(); } public class MyClass:MyInterface { public string getSomeString() { ...} public string getSomeOtherString() { ...} public string getThirdString() { ....} } Currently I set the COMVisible Attribute true for MyClass.

• SQL Server pls help - multi-parm behavior

  My report has a parameter defined as multi-select parm. It works when running for a few selections (lets say 4-6), but when selecting ALL (Select ALL) - there are maybe 10 selections - the report gets an error CLI0109E String data right truncation. SQLSTATE=22001. Interestingly - I can run for all selections if I change the parameter from being multi-select to just a regular parameter with a value of % which represents the wildcard value to get ALL possibilities. If I don't get the error when running for all selections when the parm is NOT multi-select ... then it doesnt make sense why I get a query error when I change the parm to a multi-select parameter and choose SELECT ALL. These 2 scenarios should obtain the same result ...Show All

• Visual Studio 2008 (Pre-release) How do I Bind Hierarchical data to both TreeView and listView

  Hi all, I recently discovered WPF and all the power it brings to designing rich UIs. All this gave me several ideas on how to improve an application. But first I have to make a port of the basic UI. I'd like to take advantage of the databinding. My needs are a little complex though, and even after reading several posts i'm still a bit lost. Here's the context: I have a hierarchy of objects (4 different types Module , Chapter , Item1 and Item2 ), ex: Module_1 |-- Chapter_1 | |-- Item1_1 | |-- Item2_1 | |-- Chapter_2 | |-- Item1_2 | |-- Item2_2 |-- Item1_3 |-- Item2_3 and need to display this data both in a TreeView (same structure as the hierarchical data) but also as flat list in a ListView, ex: Module_1 Chapter_1 Item1_1 Item2_1 ...Show All

• Software Development for Windows Vista Workflow Designer Rehosting and XAML Workflow

  Hi all, I am new to Windows Workflow. The XAML only workflow consists of custom activity which is defined in the 'test' namespace. The Namespace mapping construct maps Xml Namespace to the clr-namespace. I load this workflow in the workflow runtime. i.e. XAML Activation. This works fine. My problem is: I am trying to load the same XAML workflow in the workflow designer re-hosted using the WorkflowDesignerControl. The xoml is deserialised correctly and the root element 'MyRoot' is identified and added to the designer host. It cannot identify the child activities i.e. WriteLineActivity since it resides in a custom namespace and so the number of children for root element is 0. So only the root element is rendered on the designer and ...Show All

• Windows Forms Extending DataGridViewTextBoxColumn to DataGridViewHtmlColumn

  I'm tring to create a better way to present data in data columns. I've decided to extend the d.g.v.TextBoxColumn, although perhaps I should be using a higher level base class. The fist thing I've decided to support are newlines or [br] ( breaks ). this done, Im not sure the best way to calculate row height, or how to effectively set it. I've tried inside the overridden Paint method to set [ this.DataGridView.Rows[ index ].Height ], but it doesnt seem to be affecting anything perhaps I have to change a related flag so the problem, is that I now have a multiline text column that is cutting off the text because the row height is not appropriatly set. any help is greatly appreciated! -stellar ...Show All
