I have an MDI application that allows me to open different types of child windows. I can open multiple (but different) instances of the same type of child window. (Example: I can open 3 instances of child window type A and 2 instances of child window type B. All 5 windows are distinct entities and do not share data until unless the us...
I'd like to print some data to specific area on A4 paper. Are there any easy way to do like that? It's very difficult for me to find coordinate of X and Y. Below is my sample code in VB.NET to print the data. Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles Print...
I have a large number of TIFF images that I’d need to use in a WPF program (.NET 3.5 SP1 specifically and using C#). Half of the TIFF files contain color images encoded using JPEG compression and they don’t work with WPF. The “Microsoft Office Document Imaging” application handles the files fine. As Windows itself doesn’t really like the...
I'm writing an MMC snap-in that grabs some data from a database and puts it into a form. I want to update the status line to say how many records were found. I have the ASyncStatus object, but calling Complete, like the example code does, results in nothing. I'm stumped. I'm doing the call from a form, whereas the example code does it f...
Is there any way to direct C# to ignore NullReferenceException (or any specific exception for that matter) for a set of statements. This is useful when trying to read properties from a deserialized object that may contain many null objects in it. Having a helper method to check for null could be one way but I'm looking for something clo...
I'm tasked with automating the retrieval of a couple of BusinessObjects Web Intelligence reports and further processing thereof. I have no other means of access to this data (this was the first avenue I followed), so I will have to do some screen scraping. Alas, the interface seems user-only. Grr! Has anyone done this before? Like to s...
I'm passing a reference of a form to a class. Within this class I believed I could use formRef->Controls["controlName"] to access properties on the control. This works for a few labels, but on a button I receive a "Object reference not set to an instance of an object." when I try to change the Text property. Help or explanation appreci...

When working in the unmanaged world, we have to make sure that we clean up after ourselves if we have allocated memory on the heap (e.g. by using the new keyword in C++); we also have to make sure that we AddRef COM components that are created using CreateInstance and to Release it later; perhaps something like: SomeNameSapce::IObjPtr o...
I have a really simple ASP.NET web application and a web setup project that deploys the project output and content files to a virtual directory in IIS. What I want is for the MSI to automatically disable Anonymouse Access for that virtual folder in IIS. I suspect it can probably be done by writing some code in a custom action DLL, tha...
If I put a DateTime value into an Excel cell using Range.set_value through .Net COM Interop, and then retrieve the value of that same cell using Range.get_value, the Millisecond part of the value is not returned, though everything else is correct. Is this a bug? What is the workaround? I'm guessing that using the Value2 property instea...
I have a TabControl within a TabControl. I want the outer TabControl to show its tabs on the left. However, with Visual Styles enabled, left-aligned TabControls don't display properly.

I need to write a little tool for a customer to be run on Windows 98. Since this is a very small project I'd hope that I could avoid having to go native C++ and use C#. The .net Framework 2.0 download claims to support Windows 98. Are there any caveats or hitches to be aware of when installing or coding? ...
I have a COM interop assembly, and I would like to check from a .NET application whether the component I'm about to create is installed on the machine. I would like to provide a nice error message if it is not installed. Put the instantiation into try-catch is not a good solution for me, as I would like to distingwish between the miss...
