I could able to install msi file using below code and it installed sucessfully

string path = @"C:\Projects\Debug\ELSWinServInstaller.msi"; 
Process process = Process.Start(path);
process.WaitForInputIdle();
process.WaitForExit();

I tried to uninstall the same using below code, but its not working.

Process p = new Process();
p.StartInfo.FileName = "msiexec.exe";
p.StartInfo.Arguments = "/x \"C:\\Projects\\Debug\\ELSWinServInstaller.msi\"/qn";
p.Start();

Please let me know where I went wrong.

You forgot to explain what "is not working" means. Did it start the process? Did it throw an exception?

Unistallation code is not working. It didn't throw any exception. it executed each line. but uninstallation didn't happen.

That's a better description; now we can rule out any exceptions and focus on the rest. From where are you starting this? From a Windows-service?

You could check the eventlog for any errors. As a quick workaround, try putting the complete command in a batch-file and execute that from code.

Could be a permission issue.
For Vista and Windows 7, you might need to run this program as an administrator to uninstall the program.

I have administrator rights.
If it is permission issue, my installation code also should not work. But installation done sucessfully.

can you uninstall this application from a command prompt? by running the same command?

i.e.

Do you need a space between the closing quote around the MSI path and the /qn argument?

p.StartInfo.Arguments = "/x \"C:\\Projects\\Debug\\ELSWinServInstaller.msi\" /qn";

Here is an article on paging a datalist from CodeProject. Implementing Efficient Data Paging with the Datalist Control in ASP.NET 2.0[^], but after scanning that article and a few others from this google.

There are many different ways to achieve this so I have also included the Google Search Google: asp.net datalist paging example[^].

hi guys , i have made a project that has 5 forms , it's automation project and is doing the regular job of the automation , like adding,deleting,updating and refreshing , im using devcomponent dll in all the forms , but the problem here when i insert 60 record into the database (access database) after i insert the 60th record the program will fall in slumation view , when i want to add a record i should wait 5 sec after i insert a record and if other form is open and wanted to close it the hole program will stop responding for 5 or 7 sec .

i think the big reason for that its using the devcomponent . i dont know maybe the reason is sth else .

so any solution for making the program work faster ?
and one more thing , i cannot change the devcomponents form to normal form.
i dont know if you get what i mean or not ?

I have never used devcomponents but I assume they are the same as anything else - if you need to run a procedure that is going to take more than a few milliseconds you should launch a thread (look at the BackgroundWorker possibly) to do it on so the UI's thread doesn't lock.

nice solution , but is this problem is regular in automation programs ?
i mean get really slow/slow when the size of the data get increased ?

Not necessarily but it depends on how you code the data access stuff. Poor code, poor data validation etc or caching/displaying a lot of data is always going to be slow. Good code and only caching/displaying a sensible amount of data at once will be fast - all other things being equal.

Hello guys. I am copying one ArrayList into another ArrayList. However, I am calling ToArray() on my source ArrayList. Later when I try to retrieve values from my target ArrayList, it only gives my System.String[], instead of string values. Here is what I am trying

public void CopySetting(ArrayList mySrcArrayList)
{
    myTargetArrayList.Clear();
    myTargetArrayList.Add(mySrcArrayList.ToArray(typeof(string))); //copying the ArrayList
}

public GetValues()
{
   foreach (Object obj in myTargetArrayList)
   {
       string str = (string)obj.ToString(); // here I get System.String[], in str
   }
}

So what could be wrong here? Thanks for any help.

that's the main problem when you work with ArrayList, Add method simply accepts any object you pass. here you are adding the string[] returned by the source.ToArray operation. to Add the array range you should use array.AddRange.

My personal recommendation is to avoid using ArrayList in your application and use Generic lists.

public void CopySetting(ArrayList mySrcArrayList)
{
    myTargetArrayList.Clear();
    myTargetArrayList.AddRange(mySrcArrayList.ToArray(typeof(string))); //copying the ArrayList
}
