• .NET Development Naming conventions and Microsoft recommendations

  Hello, What is naming convention for different toolbox items you put on a form If I say I have a DataGridView on my form do I call it dgvCustomers or DataGridViewCustomers or CustomerDataGrid or ... it really is up to you - the naming convention is usually first 3 letters of the component, shortened (like text -> txt, or combo -> cmb) thats easily identifiable what type of control it is, then followed by the type/purpose of the control so if I had a datagridview of a customer table then I would do dgvCustomers, which means its a datagridview of customers ...Show All

• Visual Studio Solution Events does not trigger properly

  Hi, I tried to capture 'solution open' event and the 'solution before close' event using the Applition Object Model. It did not work when I first connect the Add-in and then open the solution, but it works fine when I first open the solution and then connect the Add-In. I went through the Connect.cs but I could not find any reason for this. Any idea why is this happening Best regards, Imesh Hi, Thanks for your reply. Actually I'm using class variables. As I mentioned earlier it works fine when I first open the solution then connect the Add-in from the Add-in manager but it does not work at all if i first connect the Add-in and then open the solution. <inside a toolbox window constucto ...Show All

• Visual Studio Express Editions showing a table field value as a messagebox

  I just want to know how can I show a field value on a table as a messagebox OK. you would pretty much read data into a datatable. (such as from SQL or some other source)   Then, say to get the value of Row 0 (first row) and Column 2 MessageBox.Show(theDataTable.Rows[0].ItemArray[3].ToString());     of course, make sure you check to see if rows and columns exist. you can also perhaps use a foreach loop for reading a data row at a time   foreach (DataRow curRow in theDataTable) {    //get the value of the first column    string theValue = curRow.ItemArray[0].ToString();   }     the code above basically goes through each row you hav ...Show All

• Visual Studio 2008 (Pre-release) Abort animation

  If i've started an animation with BeginAnimation is there any way to stop it  I have a program where the user can change the animation but when they do that i get realy bad performance if the previous animation isn't complete. The code looks something like this: void handlekeys(Key key) { DoubleAnimation scroll; if(key == A) scroll = new DoubleAnimation (100.0, duration); else if(key == D) scroll = new DoubleAnimation (200.0, duration);   image.BeginAnimation(Canvas.TopProperty, scroll); } If the image isn't already moving the program run smooth but if you press A and then D quickly you realy get performance issues.

• .NET Development XML/VB.net for beginers

  Hello all, I'm fairly new to VB.net, and would like to learn a little bit about the XML classes and such built in to the .net framework. I don't know any XML, but am eager to learn. I've looked around online, but can't seem to find any good tutorial for my needs. Can anyone suggest a good tutorial for VB.net and XML Thanks so much, any input is greatly appreciated!

• Windows Forms Setting the tag on an image in an imagelist

  Hi, I have a base form with a protected imagelist which inheriting forms use. I need to set the tag property for the images within the imagelist. Bizarrely, this does not seem possible. In my base form constructor, I have code like this:- imgBuySell.Images[0].Tag = "myTag1"; Stepping through this in VS2005, the above line runs without exception, but when I then inspect imgBuySell.Images[0].Tag its' value is null. Sure enough, the ImageCollection exposed by ImageList.Images is readonly. (It's still very surprising that an exception isn't thrown here). Is there any way to do this I really want to be able to put my imagelist together in the designer, so as not to have to mess around with image streams and serialised resources and ...Show All

• Software Development for Windows Vista Workflow application working in one comp but not in another

  Hello, My problem is the following: I have an ASP.NET application with a validation workflow inside. It uses the membership and roles mechanisms provided by ASP. In my computer the application works perfect, the workflow starts, does all its job and completes successfully, but when I move the application to another computer the workflow aborts after saving some changes to the database. The workflow starts, gets 2 different events (start and save) and then calls an external method to save changes to database. It saves those changes (I checked the DB and it's OK), and then aborts. The problem is that when the workflow aborts it doesnt give any exception message, so I have no idea what the problem is, and as it works perfectly in my computer ...Show All

• Visual C++ Allocating a variable-length structure/class

  Is it possible to create an instance (using new) of a variable-length structure or class When I say variable-length structure or class, I mean a structure or class that has an unsized array as the last data member. I can allocate an appropriate amount of memory by allocating a char array, and I can cast that pointer to a pointer of the class I need it to be. Unfortunately the virtual pointer seems to be unintialized so I can't call a virtual function. Or perhaps I misunderstand what is happening, but I am getting a vfptr with all cd, indicating it is uninitialized. What I am actually doing is I have a base class and many derived classes. Many of the derived classes have variable-sized data. The data is being read from ...Show All
