• .NET Development A Read-only dataset

  I have a singleton class which contain a DataSet. And also provide a property which return the dataset. How can i return a readonly dataset so that the object that is asking for it wont modify the data and the structure of the dataset Thanks, Hi Just seen this as was looking for same answer to do the exact same thing, quick method is to use DataColumn.ReadOnly = True. This will cause exceptions if someone tries to edit your lovely dataset after you've specnt all that time loading it! Obviously this is quite limited as someone could change these properties back again but it may help stop someone doing by accident! ...Show All

• Smart Device Development CF 2.0 installation on a Mobile 5 device - Persist clean cold boot

  Hi, I was wondering if a Windows Mobile 5.0 device would persist the installation of the Compact Framework version 2.0 after performing a clean cold boot I have read another post on this forum that, by default, version 1.0 of the compact framework is installed on a Windows Mobile 5.0 device, however, if I do perform a clean cold boot, then the installation of the CF 2.0 that I have done is persisted. I might be answering my own question but it would be nice to have some clarification. Thanks for your time. Paul Diston Hi, So if the installation is not persisted then by default the device would have Compact Framework 2.0 installed I have run the cgacutil.exe from the Windows dire ...Show All

• Visual C# How to get a variable from another form?

  I have form 1 that receives 2 strings from the user.  When they hit the accept button this form is destroyed and I need form 2 to have the 2 string variables. As an example on form 1 I have public string FirstName public string LastName on form2 I thought I would make a method something like Form1.GetFirstName.  But this doesnt seem to be working.  Any idea or direction you might be able to point me  Edit+   Ok I think I found out how to do it.  I made the 2 variables on form 1 static and this seemed to work.

• Windows Forms is there a limit on Controls contained in VS 2005 .NET Form ? handle creation exception

  I get a Error creating a window handle upon trying to create the 9937'th control. The number of controls when the exception occurs is dependent upon the mixture of controls created, InkEdit controls produce the exception much earlier. I was attempting to reproduce the incosistent behavior of ToolTip in my "real" application which currently has 9,216 controls (previous post that has no solution yet!).

• Visual C# Applying Property Attributes decorating a class to its member properties

  I am using attributes to supply range values for properties of an object being displayed in a propertyGrid. This works great when I am dealing with primitive types like int and float. However I have more complex data types that I want to decorate with a range attribute and have the attribute applied to member items of the object that was decorated. It should be noted that I have created custom type and property descriptors so that I have control over those description passed to the property grid. This allows me to control how the property grid displays properties dynamically. To apply the range constraints to the property I have overridden the SetValue Method in the property descriptor. The problem is when you are changing the value t ...Show All

• Audio and Video Development Starting Focus Stuck

  I set my top button to focused()=true on startup - the intention is to have one button start with focus. However in the iHDSim, I cannot nav away from this button. If I do not set focused(), then no buttons have focus, however I can click on one and then get proper navigation. <button id="AUDIO01" style="BTN_AUDIO_01" class="BTN_PLAY BTN_FOCUS" state:focused="true" /> Should be <button id="AUDIO01" style="BTN_AUDIO_01" class="BTN_PLAY BTN_FOCUS" focused="true" /> or <button id="AUDIO01" style="BTN_AUDIO_01" class="BTN_PLAY BTN_FOCUS" focus="true" /> Try both...

• Visual C++ bug in wingdi.h ?

  Hello, could someone verify this is bug : #define GetGValue(rgb) (LOBYTE(((WORD)(rgb)) >> 8)) Atleast for me it throws runtime-check-error when used. """ Run-Time Check Failure #1 - A cast to a smaller data type has caused a loss of data. If this was intentional, you should mask the source of the cast with the appropriate bitmask. For example: char c = (i & 0xFF); Changing the code in this way will not affect the quality of the resulting optimized code.

• .NET Development Can Interop Assembly built by VS2005 be used by VS2003 in some way?

  If the Interop Assembly was built by VS2005, can it be used by VS2003 I have read some articles about the impossibility of forward compatibility between .NET framework 2.0 and 1.1. Just wonder if there is a walk-around I tried to install both Framework 1.1 and 2.0 on the VS2003 machine, but I still got the error, "A reference to XXX could not be added. This is not a valid assembly or COM component. Only assemblies with …", when I was referencing the interop assembly in VS2003. Any other ideas Thanks a lot! Sean Thanks a lot, nobugz and Stan. Now it seems that I have to generate interop assemblies in VS2003 to make them useable in both VS2003 and 2005. But I still have one mo ...Show All
