• Windows Forms How do I set a ComboBox to ReadOnly?

  Hi there, I am using a form for a Client Add/Amend/Enquiry, and require a ComboBox to set certain Client details. The available items for selection are defined at design time in the Items collection property. Add/Amend works just fine. When I use the Form for the Enquiry, I set the Text property of the ComboBox to the value retrieved from the database. I want to make the ComboBox ReadOnly, but no ReadOnly property is available for this control. Setting the Enabled property to false leaves it looking very dull grey and insonsistent with the rest of the Form. The only option I can think of is to replace the ComboBox control with a TextBox control for the enquiry, which isn't great. How else can I get around this Thanks, JackSt ...Show All

• Visual Basic Referencing a function in a different class.

  I have a class, Class1, and a form, Form1. From Form1 I want to call a function, Func1, that resides in Class1. The function is a Public function as well as the class. I use the following to call the function, Call Class1.Func1. However, it gives the following error. "Reference to a non-shared member requires an object reference." I remember seeing this message before and somehow got around it. I am stumped as to what it means exactly. To me, it is worded strangely. If you are able to help then please do so. Thank you in advance. Troy L Best shown through an example. The two common scenarios that occur. I sounds as though you are trying to refer to a method in the class library without creating an object. If you wan ...Show All

But in another PC (where visual studio in not installed) I first install .net framework. Then I run my application, it works fine, but exception raised when I tried to view crystal report viewer.

• Visual C++ Wizard problem

  I tried to use VC++ 2005 Express, and when trying to start a new Win32 console application a wizard appears, but it doesnt do anything. I modified the thing in line 441 to 445 in the sdk file, but nothing happens. Ill try to be more clear. At first, I didnt change anything to that file, so, no wizard should appear. Instead, a "weird" wizard appears: View Image The "Finish" and "cancel" buttons are disabled, the only choice is to close it wuth the "x". ...Show All

• .NET Development How to retreave Name of Element When reader returns a type of Text?

  I am using XmlNodeReader to read from an Xml file, but every now and then it returns an node type of Text. The text contains the value so that is no problem but I need the name in order to know where to put the value. This is the reader code: You can remember name of the element when the reader passes it. If you have XML loaded to XmlDocument you don't need to restrict yourself with the XmlReader -- you can analyze XML directly in XmlDocument. In you sample I don't see ant text nodes so I puzzled why you troubled with them. ...Show All

  Hi, i’m planning to develop a small tank game in 3d. First i have to discuss some problems.

• Visual Studio Express Editions Which is the right way in order to manage a dynamic “connection string”

  Hello to all. I would ask you tricks regarding: Which is the right way in order to manage a dynamic “connection string” In particular, I would populate the Visual Studio interface environment to a data base (I’m using visual C# and an access db for my scope) using the data wizard because in my opinion it is helpful for that. It creates all interface objects (DataSet, UserTableAdapter, and so on) and relations like native db in quickly time and let me the possibility to manage front end as I want (maybe !!!). The problem is the connection string. The wizard execution ask me if I want save username and passwd and I chose NO (as advised) but after that, at the run form an exception raise because both those p ...Show All

• Visual Studio 2008 (Pre-release) Please could you unseal EntitySet and EntityRef?

  And make the properties and methods virtual of course. I've previously created a code-generation system that works in a remarkably similar way to the code-generation in Linq-to-Sql, a good example of convergent evolution. Much of it was written before the first Linq CTP was out, and it's been in commercial use for over a year now, very successfully. I've now left the company I wrote that for and I've set up on my own. I'm writing a new version of the system for my own company, and I'm basing it on Linq-to-Sql. Of course anyone can use Linq-to-Sql; my plan is to add a great deal of functionality that helps with writing apps. It's what I did with the previous system, and I now want to add even more. The previous system had its own equivalent ...Show All

• SQL Server Questions on translation and naming attribute

  Hello I have a few questions regarding the translations. 1. Is it possible to create this neat auto-generated date dimension in any other languages than english 2. When I use the Currency format string on my autogenerated measure groups they all turn out as $, but when I use it on a calculated member it chooses the correct currency. How can I change this for the auto generated measures 3. After creating the member, how do you define the deafult member show from the dimension. Say for example that I have DimEmpl(Code, Name). I would like the Name attribute to be the attribute showing by default. I know this is possible while creating the dimension, but what if I want to change it later Thanks // Richard ...Show All

• Windows Forms How to open Windows Forms in the same window?

  Hi all, i am using VS.NET2003 .NET framework 1.1 to new a window application. Isit possible to click the 'new' button that i have created on form1 and the form1 will change screen to form2 instead of poping up form2 Thanks Hi Mamta, thanks for quick reply. Your method did work. Mine is using VB. However, i did have a question. I notice that since you advise me to use Me.Hide() method, after 2nd form appear, and after i exit the 2nd form, the application will be still running, which means form1 will still be there, but it is just hidden away from the user. So is there any possible way instead of just hidding away the form1 Thanks ...Show All
