• Visual Studio Express Editions Register for multiple users

  Hi I downloaded and installed VC++ EE to my XP Pro SP2 PC. I did this whilst logged on with Admin rights. I registered and saved the key that I received in a .txt file. I use the PC on a day-to-day basis whilst logged on with Limited rights and, when I tried to use VC++, it said that I needed to register. I used the same key that I'd used when I registered with Admin rights but it was rejected. I was under the impression that I could register the software several times, if necessary. How do I go about registering the software for use as a Limited user Do I have to get a further key from MS If I do and register with Lim ...Show All

• Windows Forms Need some kind of modal dialog in a mdi child

  I'm developing a MDI application and I'm wondering if you could give me some ideas how to implement this demand: I want to display a form that is modal for one child window. The user has to able to switch to other mdi childs but is not allowed to work with the current child until he closes the modal form. Because modal dialogs are modal for the whole application I cannot use them. Do you have any suggestions Thanks a lot! usage:  new SubModal.Show(this) where 'this' is a Form should have read usage:  new SubModal(this).Show() where 'this' is a Form ...Show All

• Visual Studio Tools for Office Mouse hover event over a range of cells in Excel using VSTO

  Hi I have placed a similar thread to this previously but have not had too much success. I thought I would put it up and maybe word it differently. Neither VBA nor VSTO provides a mouse over or hover event. I need to be able to capture this event in VSTO within the office application and determine when certain users are hovering over a cell with the mouse. I am also an accountant who has turned to the dark side of programming. So if you do have some code to support this, it would be greatly appreciated. Many thanks to all for reading this. Cheers Dave Edelman Hi Dave, If you want to do this, you'll need to d ...Show All

• Visual C# Serialization/Deserialization

• Game Technologies: DirectX, XNA, XACT, etc. Visual C++ .NET and DirectX, problems with DrawPrimitive

  Hi. I've made a good start with Visual C++ .net express and direct3D. I have created a device and know it works, can perform some operations, however when I try to draw a simple object, say a triangle list with drawprimitive() I get this error message: An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.DirectX.dll Additional information: Operation is not valid due to the current state of the object. Here is my code, this program creates a form and DirectX device. If you comment out the drawprimtive line it works. I can change the color of the clean operation within the onpaint function and it will draw th ...Show All

• Visual Studio 2008 (Pre-release) I love DLinq. Really need n-tier support though.

  In section 7.4 of the DLinq guide it mentions that that's something you guys are looking at. Do you guys have an idea if that functionality will get in there before the product is given the green light to go-live Since most apps these days are designed as SOA, there will need to be a distributed notification mechanism. Thanks CZ The type of n-tier support we have for DLinq is simply an API that allows you to introduce objects to a new context after they have been round-tripped across the tiers. You still have to move the objects or data across the tiers yourself, and you have to figure out how to squirrel aw ...Show All

• SQL Server Remote Connection problem on MS SQL 2000

  Hello, First, I want to say I read all threads similar this thread and I couldn't solve problem. My firewall is always off when I tried to connect remotly to SQL Server. I opened 1433 port from my router's configuration page and forwarded it to 10.0.0.4:1433. When I started SQL Server service and checking "netstat" with "-na" paramters. It shows only one row as "TCP - 0.0.0.0:1433 to 0.0.0.0:0". What "0.0.0.0" means and why foreign addres port is "0". I guess, It should like to be "TCP - 10.0.0.4:1433 to OutsideIp:1433". I removed forwarding from my router and used Windows's Network Connection to forward ports. I opened ...Show All

Here's one that doesn't work : when I want to modify the progress of a while loop, it seems my trackbar does not have any influence. the goal (as stupid as it may seem) is to restart the loop before it's finished, at a certain point determined by the trackbar... what's wrong Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click maxvalue = textbox1.Text TrackBar1.Maximum = maxvalue TrackBar1.Minimum = 0 voortgang.Maximum = maxvalue TrackBar1.SmallChange = 1 i = TrackBar1.Value voortgang.Value = i While i < maxvalue TrackBar1.Refres ...Show All
