Detect Whether A User Has A Specific Redistributable Installed In .NET?
Jun 16, 2009
I have created a class which builds a Crystal report and displays it in a report viewer. However, without the Crystal Redistributable, the code crashes. How can I programatically detect whether the end-user has the Crystal DLL installed? The code I am required to include is:
I installed VB Express 2008 on my machine and it went without a redistributable file. It got download during the install. Anyone knows where I can download the redsitributable file from, so I can give it to my students?
I installed the API redist [URL] for Office 2010 (Office 2010 was already installed). Then I tried to use code from MSDN [URL] just to see how it worked. I included the code here, since it's short. At the top of the file:
Code: Imports Outlook = Microsoft.Office.Interop.Outlook
... and in the class:
Code: Private Sub SendSalesReport() Dim mail As Outlook.MailItem = CType(Application.CreateItem( _ Outlook.OlItemType.olMailItem), Outlook.MailItem)
[code]....
Unfortunately, VS2010 balks at the very first line, not recognizing the namespace. What do I need to do?Oh, and I can't find Microsoft.Office.Interop.Outlook.dll anywhere, either. Shouldn't that have been installed?
but i can't complete it if i dont know how to make it auto detecting the pathsexample: i have a combobox and only the text COD 4 MWand i have a textbox so when they select COD 4 MW in the combobox the install path shows in the textbox.
I have been trying for days now how to create a process to the user to easily create a connection to any installed data types they have installed. I have found an example right inside vb2008. I never use this because I code my own connections, but this would be real nice if I could include it or duplicate it.
I know the default install path of the app and the name of the .exe file, but is there a way to see if it is actually installed? I've seen suggestions for checking registry entries, but I don't know if this app uses any or if if varies for different users on different pc's.
I have built a web setup project using VS 2008, wherein I need to check whether IIS 6.0 Metabase compatibility is installed. I tried it by accessing registry keys specifed in here in custom actions. But when I run the installer, I the key comes out to be blank irrespective of whether metabase compatibility is installed.
To further check the problem, I created a Console app to access the same keys. When I run it on win7, the app fails. Then, I ran it in WinXP SP3 compatibility mode and it ran perfectly.
I am open to other bullet-proof means of detecting whether IIS 6.0 Metabase compatibility is installed
I am writing a application where i need to know which games are installed on a system.I have 3 ways by which i think i can detect the games
1: Scan specific parts of registry and look for key names that match with a List of Publishers. The list is manually maintained.
2: Scan the hard disk for and do same as in step 1
3: run the program in background and check for programs in memory that use a large portion of memory(which games always do) and if they use Direct X ( Which all games do except for some) then its a game.
Now i have been thinking about it and first and second method seems to be in need of a updated database ie list of publishers to make out if a particular program is game.
I currently connect to a MySQL database using the ODBC MySQL 5.1 Connector, how would I be able to detect if the driver is installed before a connection attempt?
I'm looking on the Internet but not found anything about how to detect what the frameworks are installed. Someone I can provide that code to VB. Net? TcoUpLoad (work with Vb6 and VbNet)
I want to start a new project, an application to detect drivers installed and not installed. can someone give me some details about how can be checked, what codes i need to retrieve.
I wanna detect the version of installed Visual Basic Power Packs in target system.How can I do it with Registry values (Windows from Win XP)?Or, How can I check the version of Visual Basic Power Packs assembly , e.g : how I can check the version of Microsoft.VisualBasic.PowerPacks assembly ?
how to detect if MSXML parser is installed on a machine or not. I looked for a registry entry,but unable to get one. I am writing a VB.NET application.
I have a WinForm program developed in VB.Net with Visual Studio 2005. The program needs Microsoft Office Runtime installed atleast on the computer to allow the application to run without any errors.
Is their a way to check the computer to see if the minimum of the Runtime or Microsoft Office is installed on the computer? If either isn't I would like to display a message to the user on the startup of the application that states to atleast go to Microsot's site (I have full link to Runtime Download) and download the runtime for free.
Or is their a way to include the runtime as a component with my install for the application so if it isn't installed on the computer already it will install when the application is installed?
I'm trying to figure out if specific Windows updates are installed so I can install the correct ones.I'm currently checking the WindowsUpdates.log file that is located within the windows directory, but it's terribly unreliable.In my search to find an alternative method, I cam across this blog post. It seems like a perfect fit. Unless you take into account that this is VBScript and their querying Microsoft.Update.Session.what class in WMI that would relate to VB so I can pull the info.
I have a few programs published via ClickOnce. These are highly specialized programs, and are only used by a relative handful of people, but the set of users is likely to change, and is spread over a fairly wide geographical area. The major advantage of ClickOnce....ok, for me, the ONLY advantage of ClickOnce, is that I can create updates and have them (mostly) installed when the end user runs the program. Over the brief time that I have used it, I have encountered these aggravations regarding ClickOnce:
1) The application can only be installed on a user by user basis (it can't be installed for all users at once). I understand why this is done for a general solution like ClickOnce, but it is certainly an aggravation.
2) Updates don't always appear to happen. Usually, the updates do happen when a person starts the program, but a fair number of times, the update isn't noticed, or recognized, or something. This causes the user to continue with the old version, which makes them think that I didn't fix the bug they had, which causes them to give me a raft of excrement, which results in me flipping them the bird. Much hilarity ensues (fortunately, I'm friendly with my entire user group, so this is a fairly accurate acconting of the sequence of events, except that I just laugh at them rather than replying in sign language).
3) Certificates expire in a year. Certificates are a great thing...for some situations. In my case, an alternative seems like it might be better.
4) Some settings in the manifest are so doggone hard to fix that I've nearly given up. I changed the URL that ClickOnce was supposed to go to for updates, and found it impossible to change the program to find the new location. It had to be there somewhere, and I found several candidates, but never could find the critical one.
Because of these issues, I have been tempted to write my own replacement. There are a few issues that I'd like some commentary on. For one thing, security is an issue that is hard to pin down. None of the data I am dealing with is worth a second thought. No cracking of that data would harm anybody or any thing. However, my first thought would be to have people install an app that would go to a web service to check for the existence of an updated version. If one was available, then the existing program files would be overwritten by the new files. If one was not available, then no overwrites would take place. Lastly, if the service couldn't connect, then no overwrites would take place (of course). If the files were compressed for transport, it would be kind of difficult to intercept and inject a different program into the transport stream, so the only weakness that I can see would be if somebody hacked the server that held the new version, and replaced it with something else. What am I missing here?Also, has anybody done anything like this, and if so, what else am I overlooking?
I know that using Dim currUser As String = Request.ServerVariables("LOGON_USER") retunrs the DomainUsername, but I want to know what Group that user is in say in Active Directory.
so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
I have a function read the text file line by line, i have to detect a specific word in the text file befere proceed to another action. But I can't use substring because i not sure exact location of the word.
I am very new to vb.net. I need to be able to see when a certain popup window appears in another application. The time time it takes to appear varies so I need to know when it appears and in some cases when it has closed.
I have a picturebox that the user can draw on and I need the program to detect if a specific point has been drawn on. For example, I need the program to detect whether the user drew at location (8,8) and give a basic True/False answer.
Someome knows some utilities that can detect all the API calls of a specific external application? The application I would like to detect is a console application and, being without form, Spy++ don't find it.
I think this has to do with a third party OCX control. Below is the output when the application starts. When I install my application on a stand-alone PC or most PCs in a networked environment it runs fine. When I go to some offices that have very tightly controlled networks I have problems.
The set up won't run under the user name so someone from IT must log in as administrator. They run the set up and the application installs and runs fine. The IT person logs off and the user tries to run it and the application won't even start. An error box appears and below is the report. SCANNERLib.DLL is the third party control. Maybe there is something I'm missing when I compile. Maybe the DLL registering funny under the Admin rights. [Code]
[URL] In my Windows Form, I wanted the user to give an option to draw all over the form. But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.
I am creating a project with VB2008 Express Edition. The end result will be a CD containing tech manuals in pdf format which will be accessed via various buttons on a form. I am going to include Acrobat Reader Redisributable on the CD which the user can install by pressing a button on the form if required. What I want to do is this:- When the user inserts the CD into the PC, the form will load.When the form loads, I want to search the users PC to determine if Acrobat Reader is installed.If the Acrobat Reader program is not found on the system, then display a MessageBox to inform the user to install the reader from the CD.Would this involve searching the users registry? I would need to insert in my Form1_Load sectionTarget systems would be Windows XP/ Vista with programs on the C: drive as default.
I want to make it as an Installer.how can i make it a setup file so that user double click it and the software get installed silently? I used in my program ms-access 2007 database and some other sound files which i linked to my project and some vedio files.Suggest me how can i make all the files as in a single installer or setup.
