• Smart Device Development Device Install problem - previous version of Windows Mobile software

  I know I have seen the fix for this before, but I'm not sure where. I created a nice app for the PocketPC and decided to make a cab file for installing it on a few different PocketPC's (all had PocketPC Second Edition and where Dell Axiom). When I put the cab file on the device and click it, the installation works, but I get the classic pop-up: The program you have installled may not display properly because it was designed for a previous version of Windows Mobile Software. I thought that VS2005 was going to fix this (and it probably has), but I can't seem to find out what the trick is do make the cab deployment not display this message. Tha ...Show All

• Visual Basic interacting with data classes

  I have a general question about calling web service functions from a vb windows form application. I would like when I call a function to have returned both the requested data and a string message telling me if any exceptions were generated in producing the data on the web server. So I produced a class called ReturnData and provided it with two properties called statusmessage and BlobData. I then added the class to both my WindowsForm application and the web service. I then have my web service function return the class. I don't seem to be able to read the data on the client (type issues). Is this not a proper way to interact with a web servic ...Show All

• Windows Forms Howto add custom clipboard operation to DataGrid

  Hi, is it possible to override the builtin copy-to-clipboard operation of the DataGrid-class and to replace the standard OnKeyDown (e.g.) handling by a custom one. We already have a custom GridView class derived from DataGrid. Regards, Walter Platform: XP, .NET1.1, VSNET2003 First, let me point out that I do not know what I am doing. But I did do what you are talking about.  I added a context meny to the DataGrid and included a Copy item on that menu and have an event hadler for it.  I also set the keboard shortcut for the Copy item to Ctrl-C.  Something in .NET automatically call ...Show All

• .NET Development XML-Schema (XSD) without internet

  I have just started with XML/XSD and I have a general problem of understanding. All examples in books or on the internet I have seen so far use a line equal or similar to <xs:schema xmlns:xs=" http://www.w3.org/2001/XMLSchema "> in the xsd-file. And then in the xml-file <.... xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance " xsi = "http://.....>. I'm often working on a PC that is not at all connected to the internet und thus I need a local XDS-file, not on the internet. How must this be done Entering a normal path does not seem to work.

• .NET Development oleDbCommand Fill error

  Hi, I have a dataset that is filled from a OleDBCommand that reads an excel file. This dataset is a typed dataset with a specific definition, meaning that it has some fields of type Double and others type string. For some strange reason when I tried to the Fill from the OleDbCommand I got an error that said: "Input string was not in a correct format. at System.Data.DataColumn.set_Item(Int32 record, Object value) Couldn't store < > in Colname, Expected type is Double." The Excel file has around 1500 records but in that column (Colname) in the first data row doesn't have any value but if I put a number it works, It ...Show All

• Visual Studio 2008 (Pre-release) Problem controlling OperationContract formatting

  HI, I'm working with winfx Beta2 and having a problem controlling the way OperationContract methods are serialized/deserialized. I need a pretty high granularity controll similar to the one given in asmx web methods using [ SoapDocumentMethodAttribute] [XmlElement] and friends. (e.g. attributed controll over the method paramters elements names, name of return value, name of result element, etc). Thank you Sowmy, Regarding the dup thread, you're right, it started as two distinct problems that became one. As for the feedback you requested, for me, the MessageContarct paradigm  has two main drawbacks: 1. Migrating ...Show All

• Visual Studio 2008 (Pre-release) GridLengthAnimation

  It would be great if MS provided a GridLengthAnimation type out of the box. I would use this to animate the width of a column in a grid. Can't use DoubleAnimation because it's not a double. It's a GridLength. And I can't just DoubleAnimate the GridLength.Value property because it's not a settable property. Thanks. You can also do this..... /// <summary> /// Animates a grid length value just like the DoubleAnimation animates a double value /// </summary> public class GridLengthAnimation : AnimationTimeline { /// <summary> /// Returns the type of object to animate /// </summary> p ...Show All

• Windows Forms listbox item refresh

  so, i have a listbox containing a collection of custom objects by default, listbox uses toString() to determine the display string for the item however, if i update the value of an object in the listbox's item collection, and would like to have that displayed, it looks like the only thing i can do is to: 1. remove the item 2. insert it back the 'refresh' method doesn't requery the result of the 'toString' method on the object. is there a better way to do this The custom objects need to have an event : PropertyChanged, so when ever you call one of the setter, this event should be fired. the listbox should lis ...Show All

• Visual FoxPro Vue File Format Structure Needed

  Can anyone help me on where I can find information on the structure and format for the VFP Vue files that are created with the command: Create View MyView.Vue Please thanks, Terry Hi Terry I understand what you are saying, but I would still say that a better approach is simply to set up programs that replicate these environments and that will accept a parameter (or use something like CURDIR() to define the starting location. By implication neither your table names and relations, nor your relative paths, are changing, all you need is to define a different root location.
