How An Application Like GameSpy Or GameRanger Launches Applications And Is Able To Sync With Other Users(all Joining Together)
Feb 14, 2010
I have been trying to figure out how an application like GameSpy or GameRanger launches applications and is able to sync with other users(all joining together). I have been under the assumption that it was just simple command line switches being used. The more I look into it the more I don't think that is the case. I believe they are hooking into a game's API to do so. My question would be, using OllyDbg I was able to get the memory address of a Text display in the game(The game you are about to create's name).The default is "TEST SESH", and if you highlight the field and hit enter you can edit it. I was wondering if anyone could give me incite on how I could set this text through a DLL injection?

Do users of windows applications have to have the database application installed if your program uses databases to store information? For example, when making VB2008 programs, if I use the visual studio express database (.sdf), or maybe a MSAccess database, to store information within my visual basic program...when I deploy the application to the users, can they run the program okay even if they don't have MSAccess installed on their computer?Also, do I need to have MSAccess installed in order to write programs that use MSAccess databases?

I've written a very simple form application that launches a bunch of shortcuts. There's one particular one I want to launch, but it's got a lot of switches with special characters. I can't figure out how to make the switches/arguments into a string so that VB2010 will pass it to the executible cleanly.. Here's what I did, I'm sure it's laughable, but I guess everyone starts somewhere:
Private Sub Button11_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button11.Click
Dim MyString As String = ","/CitrixShortcut: (1) /QLaunch "CHCFarm:Citrix Console""
Process.Start("C:Program FilesCitrixICA Clientpnagent.exe",MyString)
End Sub

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

I have a Visual Basic .Net form (launches after the splash screen tests database connectivity) and it is not focusing above other existing windows on launch. How do I get it to focus above all existing windows and Windows Explorer windows?

I am creating a Visual Basic 2008 .net application that will be using the Sync Service for ADO.NET on Windows 7 Ultimate. The back end database is SQL 2008. Below are the basic steps I take when the error occurs
a. Add a Local Database Cache item to my application
b. Use the Configure Data Synchronication wizard for the setup process
c. Click the OK button to accept changes
d. An error message is generated, "The given key was not present in the dictionary".
I have attempted this several times and the error message presists no matter how I vary the options. I have also installed Microsoft Sync Framework 2.0 successfully but the error persists. I also have all the following Dlls referenced in my project:
Microsoft.Synchronization.dll,
Microsoft.Synchronization.Data.dll,
Microsoft.Synchronization.Data.Server.dll,
Microsoft.Synchronization.Data.SqlServer.dll,
Microsoft.Synchronization.Data.SqlServerCe.dll.
I am sure I don't need all of these references but I figured it does not hurt to have them all referenced for now. I have the latest OS service and Visual Studio 2008 service packs.

ok so heres the scenario. Ive made an app in visual basic 2010 that calls another application in c:pinger 2.0. In the directory pinger 2.0 are many sub folders from 15-500 named 15-500. I have a button that does this:Shell("c:pinger 2.0" & TextBox1.Text & "pinger.exe")
so basically if i type 15 it launches c:pinger 2.015pinger.exe which works flawlessly however this pinger.exe requires a host file thats .txt based. My problem is when it launches pinger form subfolder 15 it cant locate the hosts.txt. To do a little troubleshooting i loaded the hosts.txt file in the same directory as my VB app and then it worked just fine but this is no good.the whole point of having different subfolders is because each sub has a different hosts.txt file.So what im experiencing is when i call pinger.exe its looking for the hosts.txt file in the root of the VB application and not the subfolder 15-500 is there a way to call a program and let it run from its original location so it will find the hosts.txt file in the correct subfolder?
i can upload my project if this mumbo jumbo has confused you, perhaps theres some ,vb"switch" i can run? like:Shell("c:pinger 2.0" & TextBox1.Text & "pinger.exe",vbrunwhereyoursupposedtoplease)

I have a VS 2008 Solution in VB.Net that has 2 projects - a Launcher and the App. The Launcher is what runs first, checks to make sure the App has all the latest files from the network, etc. and then launches the App. The Launcher allows the user to select their environment (Test, Production) then passes those values into the App.exe as command line arguments.
This works fine when running normally, but when trying to debug this, I'm trying to figure out how to start Debugging from the Launcher, then pass the selected Environment into the other project so it can read them as command line arguments.

i am wondering if there are any case studies / white papers available comparing web applications to remote desktop applications on running on comparable hardware? What I am trying to get at is if a web application can support more users, as far as hardware resources go, than the same windows based application running on terminal services?

I have a legacy vb6 application that uses a shell command to launch a newer .net application. It's a very simple command, just launches an app. Here's the problem. When I run the .net app through the shell command, it tries to connect to a database that is not referenced in it. If I double-click the .net executable, it runs just fine and connects the way it is supposed to. Normal, no problems. Only when I run it from the shell command do I have problems. I have checked everything I can think of and simply can not come up with a reason why the app would behave differently when launched from a shell command.

I have a few questions regarding the GUI applications.I am aware that Console applications are non-event based programs which do not have the pretty GUI interface.Having done C/C++ on *nix with a main() as the entry point and in Windows 3.1 with WinMain as the entry point into the application, I am trying to figure out the entry point into the VB application.

I have created an application that will run several other Engineering applications from within it.
I have my main form which will have a button on it for each application that has to be run. All the other projects are complete and have their respective '.EXE' files, which I have added to the main project.
I have coded one of the buttons to start an application, this is as follows;
Private Sub btnCoordsCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCoordsCalc.Click
Process.Start(My.Computer.FileSystem.CurrentDirectory & "Hole_Coordinates_Calculator.exe")
End Sub
This method works OK and does start the application. So my question is; Is this the correct way to do it, or should I import the whole project into my main project?

I have several different applicaitons that were originally created with Visual Studio 2005 / .net framework 2.0 / Windows XP that got common settings from an App.Config file on a network share. Each of these applications has an app.config file with the following:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings file="\fileServerconfigcommon.app.config" >
</appSettings>
</configuration>
I am now trying to make these applications work in a Windows 7 / .net framework 3.5 / Visual Studio 2008 environment and can't seem to access the settings in \fileServerconfigcommon.app.config in the same way the old environment allowed. I'm wondering if there is some new way to do this. I need to have the applications read their settings from a common file on the network share (having the applications take their own copy is not accpetable).

I recently finished an application which I spent a long time making, but when I sent it to my friends so they could beta test, everyone single one of them said it stopped responding on start up. I took the .exe out of the project>bin>debug>application.exe and thats what I gave them, and it doesn't crash for me, so i was wondering what might be causing it to crash, or if they would need extra files for it to work properly?
Also, when my friend opened it, he says he got an error that says:
Name: Microsoft .NET Error

I use a fontdialog box in my application allowing users to change the font details within my application. This works fine but unfortunatly I don't seem to be able to set the values in the dialogbox as they are read only.
Basically if the user has Bold Wingdings set and wishes to change it to something else then when they open up the fontdialog box I would like to be able to set the font to wingdings and bold so the user can see what they previously selected. Word seems to do this so why cant I?

I'm using the Application Updates option in Visual Studio with 'Before the Application Starts' checked.Users are complaining of canceling the update and then finding out they really want the update. When they decide they want to update there is no way for them to update the application until I publish a new version, because once they cancel the dialog box it never shows up again.
Is there a way to create a menu option to force a check for updates?
Kind of off-topic... Are there any open source Application Update programs for .NET?

I am writing an App that automates file uploads from users desktops to a specified file server. On the first run of the app, I need the user to select a file server and save it for all other users of that PC. I thought I could do this
with application settings but it appears it is not suitable for this purpose. I need suggestions on how I can make this work.
I thought about a registry setting but the user may not have permission to edit the registry based on group policy/security settings.
I also thought about creating an XML file with the file server name that I can read from the installed project directory, but I was hoping there was a more streamlined way.

I want to build an application that checks every second for certain windows and then react according to that.
My Goal:I'm building the application for a pc in a Students Home with about 10 users. To create 10 different user accounts for windows will be annoying and crowded, because new people come in every year(or couple of months) and then old accounts have to be deleted and new ones created.
I want to build an application that accepts folderPaths or window names.Lets say user1 creates a folder with the name "Susan" that she wants to protect (her personal files/picture/work will be stored there. She opens the application, selects the folder. The application saves the folder path and her password that she enters.
If the application detects that a user is trying to open/move/delete/copy/whatever that folder, the app must pop up a password box. Correct password gives her the freedom she wants, wrong password just ignores the open/move/delete/copy/whatever command.
