• Visual Studio Express Editions They've Vanished?

  All of my menu items and toolbar items have vanished, all the code is still there, all the references to them are still there in each of the properties windows it's just that the icons are not there. Is there any way to get them back Has anyone identified the source cause of this problem, or is it just a bug I've experienced a similar problem as Graham twice now. One munute my menu items are present, and then they're gone. I'm not sure when it's happening, but I can telll you that I am NOT manipulating the menu during run-time - It's a static structure... (BTW - VS Hotfix KB920805 is installed) ...Show All

• Visual C++ Static object initialization and thread safe

  I have ran into a situation that is very werid. Could anyone help me This a C++ application built and debugged on Visual Studio .Net 2005. Basically I'm implementing a singleton class using double check locking pattern. I have read many arcticles about how this pattern is not thread safe, but my problem is slightly different. Here is the pseudo code: MyMutex.h/cpp class MyMutex { public: ...

• .NET Development Node vs. Element? Collapsing... Elements?

  I've been developing a customized C# XML serializer, because of the lack of support for Generics using the XmlSerializer class, and I use the XmlElement quite a bit. One of my questions is what is the major difference between a Node and an Element I see that the XMLElement class inherits from XmlLinkedNode, which inherits from XmlNode, so does the word "element" simply define a "group of nodes", but can be a single node I am just curious about is all. Whatever the "group" is, my real question lies with how to programmatically collapse these "groups" My Xml file will be representing a config file that can easily end up to be 20+ pages long, so it would be really helpful to collapse ...Show All

• Smart Device Development Serial Port Mapping Problem on Pocket Pc 2003 Emulator

  Hello all; I am developing an RFID reader project, using VS2005 C#.NET on pocket pc emulator. My rfid reader device is connected on serial port of my computer. I can read and write to serial port of reader on pc application, but when I try to use emulator in my software, I fail to communicate. My device is on COM2. I map it to serialPort1(I guess it means COM1) on emulator, then I write my software which tries to communicate with COM1, then I deploy it. It seems to open the port, but when I try to send message, the program freezes. The weirdest thing is that, I can only open COM1 port on emulator, even if I map my device to serialPort2, or even if I don't map anything. I guess this means that mapping is not working ...Show All

• SQL Server Remark some task or data transformation component

  How could I remark my script component, It is isolated, I just wanna check something without losing the long script written inside. Thanks, Fahad I have an script component amid many transformation components. The script component just "trim"s the string values, and pass same data on. I just wanna see what happens if I remove the component. I have bypassed that script component now it is isolated. But I cannot run the package, since the isolated script component gives an error.

• .NET Development C# custom class - calling an sproc - completes, but no data inserted

  I have an asp.net (C#) app calling an sproc from within a class. The sproc first verifies that the item being inserted does not already exist. It then adds a row to 3 different tables (nested sproc). Running the sproc from the "Run Stored Procedure" menu item in Visual Studio .NET 2003 works perfectly. But, when I run the actual app from IE, no data is entered into the tables. The output from the Database Output window indicates each of the statements finished correctly; however, when I look at the table using SQL Enterprise Manager, the data has not been added. Am I missing a commit or something All sqlcommand parameters are set from the class properties. I make sure they're all set before calling the sproc (even though som ...Show All

• Windows Forms Exception thrown when changing opacity

  I've got a form that's shown from some code in a c# Word Addin. I've had to call the SetParent API function to make this form a 'child' of Word (I wanted the form to behave like the Word Find dialogue) like this: if ( Win32 . SetParent ( this . Handle , hwnd ) == IntPtr . Zero ) (where hwnd is the handle for Word) I also fancied having the form 'go a bit transparent' when it lost focus (i.e. when the user started typing in Word) but when I put something like this in the decactivate event of the form this . Opacity = 0.35 ;  I got this rather nasty exception: System.ComponentModel.Win32Exception was unhandled Message="The parameter is incorrect" Source="System.Windows.Forms" ...Show All

• .NET Development dummy OracleClient question

  Hello, I have a really, really newbie question: what do I need to download to enable working with OracleClient I think I need the Oracle Client 9.x from Oracle, so I went to http://www.oracle.com/technology/software/products/oracle9i/htdocs/winsoft.html , but the file size is huge! Why is an Oracle client so big I would think the server is big, but a client should be small. I apologize if I'm asking a dumb question, but I haven't worked with Oracle in 5 years and I just don't remember the setup. Thanks, Tibs No problem, glad to help.

• Game Technologies: DirectX, XNA, XACT, etc. Problems on resize

  Hi, I’m the coordinator of Jad Engine, a MDX 1.1 open source 3d engine. We have had one bug around for several months that we are unable to solve related to resizing the device. At the start, we used SetAutoDepthStencil = true when creating the device, and there was nor problems with the resize. But nowadays we do it manually and SetAutoDepthStencil is false. But when we reset the device, the D3D debug tells us that one surface has not being liberated. That surface is the DepthStencil we just created, because if we don’t create it, the reset works. The Microsoft.DirectX.Direct3D.Device.IsUsingEventHandlers is set to false as we create ourselves the VertexBuffers in DEFAULT mode and that’s the only way that they don’t give us an error on th ...Show All

• Visual C# Cross-working between two or more Forms

  I suspect this is a very basic question, which I just haven't encountered so far in the literature. Writing in C# within VS 2005 for Windows Forms development, I want to develop an application which consists of two or more different Forms. I want one of these Forms to contain all the control buttons for driving the application, these buttons causing different actions on the other Forms. When I tried rather simplistically to create and run a trial application consisting of two Forms, with a button on one intended to change the text of a label on the other, it failed at compile time, with an error message saying that my reference to Form2.Label1.Text, was not allowed, IIRC because of the security settings.
