Hello experts

Its been a while since ive played in visual studio as ive been more a powershell person and looking for a bit of guidance. I was mainly writing this as a vb app instead of powershell for performance reasons in terms of faster launching but you might indicate this is incorrect. Amongst other things the app I was writing needs to work with the windows 7/10 credential manager to check if a credential already exists or not and if it doesn't preadd the username and target name to minimise confusion amongst endusers who are typing the incorrect credential and causing problems. So basically the command line I need to encapsulate into vb is

Cmdkey /list:ourtarget.provider.local

which will either return the credential details or say * NONE*. In powershell its relatively simple to pipe it with | foreach-object and check if the credential is there and im just wanting advice on how to do similar in VB or is there a better inbuilt way for vb to work with the windows credential manager ? I'll be adding the credential if it doesn't exist using info pulled from our AD which ive already got sorted in the code just a bit stuck on executing the external cmdkey program from within vb and parsing it

We have an ASP.NET application which uses multiple web services. It's an old project in Visual Studio 2010 that included the web services using dynamic discovery.

The project was initially published to a development machine running Windows Server 2003, but was changed to a 2008 R2 server some time ago. I'd now like to update the web references but trying to do that from within VS2010 results in the error -

There was an error downloading 'http://server.address/WS/WS.vsdisco'. The request failed with HTTP status 404: Not Found.

If I try to open the vsdisco from a browser on the server it returns -

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

I've added the HttpHandler entry for vsdisco files to both the machine.config and web.config files on the server. The vsdisco file opens fine from a server running IIS6.

Is there a fundamental difference between IIS6 and IIS7.x that means this simply won't work, or can I just add a MIME record for vsdisco files? If so, does anyone know what the MIME type should be? I've tried 'text/xml' but that just returns a schema error.

I know this has been superseded by WCF services, but for the time being I'd rather not have to make a more major change to the code to implement that. The web services have been built using the .NET 2.0 framework.

Many thanks,…

Hi guys.

I'm using this code to read a text file locally and do the word search as needed but the problem is that the file which this app will be reading will be online on a web server and the problem is that the code I have now to read this text online I don't seem to figure out how I can split data so that I can still do word search just like how I do to a local file. Here is the code I use to read local file:

while(!in.eof() && getline(in, line, ','))
								if((offset = line.find(ID, 0)) == string::npos)
									id = atoi(line.c_str());
									in >> dat;
									getline(in, NUMBER, ',');
									getline(in, line, '\n');
									KEY = (int)atof(line.c_str());
									if(ID ==id)
										ID = id;
										//dst = dvs;
										va = KEY;

Open in new window

Now this code part is the essential part of code as its what I want to be able to do in the following code which is the code that reads a file from the web.

    #include "stdafx.h"
    using namespace System;
    using namespace System::IO;
    using namespace System::Net;
    using namespace System::Text::RegularExpressions;
    int main(void)
        Regex^ rxSubTitles = gcnew Regex("\\d.*>(?<subtitle>.*)<");
        String^ strFileIn = L"";
        WebClient^ wc = gcnew WebClient();
        StreamReader^ fileWebIn = gcnew StreamReader(wc->OpenRead(strFileIn));
        String^ strData = "";
            strData = fileWebIn->ReadLine();
                // take ONLY the subtitle without additional decoration
        return 0;

Open in new window

This code simply gets all the Titles.

Here is my text file structure:


Open in new window

As you can see each line has 3 data fields and

Open in new window

is the data separator and as you can also see that the 3rd field can sometimes be empty. I think if you can look at the structure and also look at my first code even though I didn't post the complete code on the first code but I think that s the main part which you may need as its also the main part I'm having problem with when trying to apply it to the second code.

I have 2 forms Form1 and Form2. Form1 is the core form or the main application first form which runs first then at some point it hide it self and show Form2, the problem now is that I want to also reshow back Form1 when Form2 closes.

Anyone know how I can have that. Currently the forms do hide form1 and show form2 but I can't include form1 on form2 because form1 has already had form2 included in it. I'm using Microsoft Visual Studio 2010 CLI application.

I need to sort my data in a particular sequence in visual studio and not in A-Z or Z-A format. Suppose i have a table in visual studio with two columns Product and quantity:

Product      Quantity
Copy      5
Pencil      6
Eraser      1
Marker      10

and I want the result as:

Product      Quantity
Pencil      6
Eraser      1
Copy      5
Marker      10

step i should take.

I dont know how to start the project templates adding in visual studio, whether the windows service (C#) template then
click on the File menu on the Visual studio 2015 to add the windows driver to the Windows Service or  vice versa.

Would  really appreciates someone help in sorting this issue out.

I have a table with the following columns
Ticket Number

There is a separate table listing all assignees - something like a list of all the staff.  Each ticket can have multiple assignees.  Assignees can work on multiple tickets.

When the user selects a ticket I want a list box to show total staff with the assignees on that ticket highlighted.  The user should be able to add and remove assignees from a given ticket.  The list of selected assignees need to be passed to an SQL stored procedure.
I'm using C# in Visual Studio 2010.

Hi All

I have the following issue below with VS2015 ,it will not allow me to connect to TFS however in other versions i can, see below.

I need to stop the user register if the username is contained in the password
this work for me


Open in new window

But i need it to stop the registration if is

Ernesto or ernesto

at this moment just if is  ernesto or ernesto  quits

i mean, how to do it no mater the  CASE!

Everything was going well... playing around with Visual Studio 2017 for the first time...

Had a weird problem (#1, but not really what the question is about where even though I set the Assembly Name and Root Namespace names, ApplicationName was still returning "WindowsApp1" when referenced... so I thought maybe it's building using that temp name when run from VS IDE.  So I compiled it into an app and deployed it.  Same result...

So I try re-opening the project - I can't open forms!  I can a new form, but when I try to open the main form, the only "main" reference I have is main.vb.  And when I open that, I don't have any code either!  I have one other form in the app and I can't open that either (but the code is visible).

I'd really like to continue this project but I need to see the forms!  HELP PLEASE!?!

(Classic Windows Forms app).
