• Visual FoxPro VFP7 COM+ error while calling from ASP.Net 2.0 on IIS6

  Hi, I have an ASP.Net 2.0 application which interop with VFP7 COM+ (using DCOM). It was running fine on IIS5, WIndows 2000. Recently I migrated the server to Win2003 and IIS6 is running on native mode, and I couldn't get the COM+ running, below is the information and hope someone here could help: 1. If the application pool identify set to 'Network Service', I can't even create the COM+ object in the ASP page even though I have granted the 'Network Service' account with neccessary NTFS folder permission. 2. If I change the identify to let say Local System or Administrator, I have no problem to create the COM+ object in ASP page, and VFP codes in the OLEPUBLIC class Init event has actually being processed as well (for example I put a Create ...Show All

• Visual Studio Team System Custom History Control

  We would like to add a tab to the work items that is similar to the History tab in its functionality, but only lists times where the work item state transitioned and who did it. I could figure it out by reading the database, but this isn't recommended since the DB schema could change. Also, I would need some way to perform a query when the work item's form is shown. I could add a trigger to modify a custom field that contained the information, but again, the trigger would be referencing the schema. Also, I don't like adding to the database in this fashion. If there is an event that is fired every time a work item is changed, I could have the event call a web service and let it modify a custom field if the state had changed. This s ...Show All

• Visual FoxPro How to overwrite a disk file that is read-only?

  While trying to run oFS = Createobject('Scripting.FileSystemObject') ...... oFS.CopyFile (file1,file2,.T.) I get an error on statement # 2 if file2 is read-only. It is a errant situation. This file is not supposed to be this way. I have to transfer about 2,000 files each time and a couple of them turn out to be this way for no apparent reason. The program breaks down. How can I change this property on the fly programmatically Thanks.

• Windows Forms Form Drawing

  Hi, I just started working with Visual Studio and C# and I'm trying to build a simple application. I'm spawned a few balls and made them move around. After hours of trying to figure out how to use the double buffer feature I just figure it out. My Problem: Now My problem is that the application is very slow when the form window is expanded.I was running all my tests in a 200*200 window. There is a huge performance issue between 200*200 and 800*800. My guess is that Graphics g.Clear(Color.Black); is taking too much resources. But I don't know, I'm new to this stuff Question: Can I NOT re-draw the background but still clear the balls Thank You Here's a poriton of my code: private void Form1_Paint(Graphics e) { Graphics g; ...Show All

  I have created a class called clsserver and it inherits from the Picturebox class. Basically it is a picture of a server and displays as different colours as the status of the server is found, ie green is good, yellow might be a problem and red is can not access. With the Gui I can display multiple server on the screen ie 15 of these clsserver classes left to right, top to bottom.

• Windows Forms Samba Struggles

  I am having a problem that I have seen a few other places, but no solutions for. I cannot connect to samba. I can see the computer on the network and I can even ping it (Name and IP address), but whenever I try to access it says "Windows cannot find \\gnu (or \\192.168.0.20 ). Check the spelling and try again. I have already changed the security policy to "Send LM & NTLM - Use NTLMv2 session if negotiated." Does anyone have any other suggestions.

• .NET Development Launching a web browser with URL in a string

  Hello! I'm using .Net 2.0. I'm launching the default web browser with the following code: System.Diagnostics.Process.Start(url_string). Url_string is a string variable that contains the URL I want to open in the browser (e.g. "http://www.searchexample.com=q&e=aakkonen&esim"). The problem is that if the string contains scandinavian characters (a, o, a) or the characters &, ", #, they will be converted to some kind of HTML code. For example %E4 stands for letter "a". How to open the web browser without changing the string at all For example video.google.com. Yes, converting the character to %E4 will work but then for example IMDB.com search engine won't work because it is ...Show All

We're talking about converting between a string and an object. The ConvertTo function relates to conversion from the object to a string. The CanConvertFrom and ConvertFrom functions relate to conversion from a string to the object. So why does the CanConvertTo function also relate to conversion to the object Surely you're looking for the destinationType to be a string here ...Show All
