Windows Forms UserControl with ComboBox
My aplication needs a usercontrol consisting a combobox. So I have to provide the commonly used propertiesfor the comboBox for this usercontrol as well. I build this UserControl DLL and using in some other Windows Forms, but then some problems arises. I have few problems in that: 1. There is a property called "FormatString", I have attached the editor "FormatStringEditor" also with this while declaring this property. But when I try to use this property in the "property-pane" I am getting an error Object Reference not set to an instance of an object" 2. I have also exposed the property for "Text" and "Items" and attached these properties to the ComboBox corresponding prop ...Show All

Hi there, I'd like to start developing with those thingys and would like to know how I can send a message to an open application and print it's response (using sorta API without COM). Is there any way throughout a gadget Greets, Arne You can run an application with parameters, if that's any help. "SendMessage" can't be done directly, without creating your own EXE/DLL to do it. How is your application expecting the message to be sent And, how does it respond ...Show All

I am learning how to consume a web service. I have created 10 web services. And I have not been able to consume one.

Software Development for Windows Vista The 64-bit Intel version of App Verifier 3.3 fails to install on our 64-bit Intel machine
The 64-bit Intel version of App Verifier 3.3 fails to install on our 64-bit Intel machine. When we use the AMD version of the installer, it does not generate logs when we run our MSI installer package. The installed application runs correctly in Test Case 4 on the 64-bit machine. Hello When you use Application Verifier, the version that you use depends on the bit verion of the application that you are testing. For a 32-bit application being tested on Windows 64-bit, you would still need to use the 32-bit Application Verifier. The ia64 version of Application verifier is only for Itanium systems. For 64-bit applications on and Intel EMT64 system, use the AMD64 version of Application verifier. Thank You Thomas ...Show All

I have just tried to install Vista Ultimate onto my laptop using my Windows Vista Disk from MSDN. I burnt 4 disk's from the iso image dvd(only 4 available on the dvd) onto cd.

Visual C# "Private" Clipboard ?
It may sound bizarre but I have a serious need to create my own "private" clipboard for storing very simple basic strings with the stipulation that I am able to copy my strings to it programmatically and could use the clipboard menu to paste the code anywhere at a cursor. I would appreciate if someone could suggest a conceptual way to do it if it is possible. I also want this clipboard to be completely independent from MS Windows clipboard. I know there are commercial applications with clipboards of expanded options, so it should be possible in theory. Thanks. How do you want to have a private clipboard but paste from it like a public clipboard This is not posible because all application the have clipboard support ...Show All
Internet Explorer Development Getting information about an IHTMLElement
Hey, So this should be easy, but for some reason I can't get it working. I have a pointer to an IHTMLElement which is an anchor. I want to get out the href and if theres an img in there, the src of the image and its rect on the screen (x,y, length, width). eg, if the html is <a href="blah"><img src="haha"></a>, i want "blah" and "haha" I got the href by calling getAttribute, which was easy enough. I can't figure out how to get the src of an img if its there. Heres what I've tried so far: 1) innerHTML and innerText - there methods give me a BSTR null, even when there is an img tag between the <a> and </a>. 2) get_children() - I called get_children, then ca ...Show All
Smart Device Development Exception from System.DLL when calling a webservice
Hi all; I am working on a database synchronization application and have a web service that my CF 2.0 application calls repeatedly to download or upload data as required to keep my field devices updated. I cannot use replication with SQLCE due to some data security and retention requirements for uploads - so I had to implement a web service to do the data transfer and other work for the devices. I create one instance of my webservice class, then call the methods on the class to send or receive data from the webservice. The issue is, during each call, system.dll throws a System.URIFormatException, seems to catch it (I don't get the exception in my code) and then goes on transferring the data without error. I know that the exception ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Heightmap Collision testing
This question has been mocking me all day. I know it's doable, I have even used such a function somewhere long ago, and I have even found quotes of people saying "the calculation is easy and quick," however, I cannot find an example of heightmap collision testing. In other words, I want to be able to type MyLandscape.GetHeight(x,z) and it'll return the height (y) at that point. Now, this is not a simple, find the vertex at (x,z), and return the array value. There is distance between each vertex so, (x,z) wouldn't always be a vertex location. If I recall my calculus from ages ago, I think I remember there being a way to do this, but I don't remember. Answers or links would be deeply appreciated. ...Show All
