Hello,

Assembly probing - how to instruct runtime to look under bin folder instead of GAC?

According to this article[^], runtime default behavior is to check GAC BEFORE other location.

So the fact that I added probing hint didn't change this (i.e. runtime is still binding to dll in GAC):

<br />
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"><br />
			<probing privatePath="bin;bin\Debug;bin\Release;"/><br />
		</assemblyBinding><br />

But this is NOT what I need, I actually need it to go bin folder for it?

This may be relevant.[^]

Also how can I check which version is being binded to? I launched "fuslogvw" but it is just sitting there. Nothing shows for some reason... it's giving me headache because (a) dll in GAC no debug information (even under DEBUG build)
(b) nHibernate mapping files loading - my mapping files are in bin folder, not in GAC

Thanks

AppDomain.CurrentDomain.AssemblyLoad

and

AppDomain.CurrentDomain.AssemblyResolve

You may be able to write some code with those events to accomplish your goals.

sorry not exactly sure

you're saying i should implement event handlers to assembly loading/probing, set a breakpoint and see where it takes us?

I am suspecting perhaps it has to do with signing or that I've accidentally put one of System.Remoting.xxx dll into GAC (I ran a util which installed my dll's into GAC - which may have incorrectly installed System.Remoting.xxx into GAC ...)

so dead

When the run time detects it is time to load an assembly it will call that method first allowing you to provide the assembly. You can then load whatever version you wish.

ah... ok...

i'm starting another test now though. Restore my monday backup and run the test cases again. If that works, it means I didn't screw up my GAC by installing any System.Remoting.XXXX there.

If no, then ...

awe... i cant think straight now all i can do is to watch test cases run after i restore backup my mind is just too fried.

good stuff - just ran test cases against MON backup it's okay --- meaning:
(1) I lost up to MONDAY but not more
(2) My machine's GAC is *NOT* the problem

I will give my mind some rest before coming back next WED, then add back what i did last two days, bit by bit Frown | :(

Thanks for your advice though

hey...

is this what you meant?

<br />
static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)<br />
<br />
  43: {<br />
<br />
  44:     Debug.WriteLine(string.Format("CurrentDomain_AssemblyResolve reports that '{0}' was unresolved.", args.Name));<br />
<br />
  45:  <br />
<br />
  46:     // args.Name == "ChildAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"<br />
<br />
  47:     string[] parts = args.Name.Split(',');<br />
<br />
  48:     if (parts.Length > 0)<br />
<br />
  49:     {<br />
<br />
  50:         Assembly assembly = Assembly.LoadFrom(string.Format(@"{0}\{1}.dll", assemblyPath, parts[0].Trim()));<br />
<br />
  51:         return assembly;<br />
<br />
  52:     }<br />
<br />
  53:  <br />
<br />
  54:     return null;<br />
<br />
  55: }<br />
<br />
  56:  <br />

Thanks!

oh this looks like it...

<br />
  Assembly currentDomain_AssemblyResolve(object sender, ResolveEventArgs args)<br />
        {<br />
            //This handler is called only when the common language runtime tries to bind to the assembly and fails.<br />
	<br />
            //Retrieve the list of referenced assemblies in an array of AssemblyName.<br />
            Assembly MyAssembly, objExecutingAssemblies;<br />
            string strTempAssmbPath = "";<br />
	<br />
            objExecutingAssemblies = Assembly.GetExecutingAssembly();<br />
            AssemblyName[] arrReferencedAssmbNames = objExecutingAssemblies.GetReferencedAssemblies();<br />
	<br />
            //Loop through the array of referenced assembly names.<br />
            foreach (AssemblyName strAssmbName in arrReferencedAssmbNames)<br />
            {<br />
                //Check for the assembly names that have raised the "AssemblyResolve" event.<br />
                if (strAssmbName.FullName.Substring(0, strAssmbName.FullName.IndexOf(",")) == args.Name.Substring(0, args.Name.IndexOf(",")))<br />
                {<br />
                    //Build the path of the assembly from where it has to be loaded.<br />
                    //The following line is probably the only line of code in this method you may need to modify:<br />
                    <strong>strTempAssmbPath = txtAssemblyDir.Text;</strong><br />
                    if (strTempAssmbPath.EndsWith("\\")) strTempAssmbPath += "\\";<br />
                    strTempAssmbPath += args.Name.Substring(0, args.Name.IndexOf(",")) + ".dll";<br />
                    break;<br />
                }<br />
	<br />
            }<br />
            //Load the assembly from the specified path.<br />
            MyAssembly = Assembly.LoadFrom(strTempAssmbPath);<br />

Hi,

I am developing a application in which i need to get the list of installted programs on windows server 2003, from add or remove programs. I am using C#. any idea how to do it.

Currently I am having this code:

const string INSTALLED_SOFTWARE = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";

string[] softwareInstalled;

try
{
regKey = Registry.LocalMachine.OpenSubKey(INSTALLED_SOFTWARE);
softwareInstalled = regKey.GetSubKeyNames();
regKey.Close();
}

From this I am getting complete program list. But I am looking for specifically add/ remove program list.
Thanks in advance,

Priyanka

Hey guys n gals Smile | :)

I am creating an app where there will be several 'steps' of which need to be completed before the final form is shown. Is there a way where we (I) could use one panel for each step and simply show and hide appropriate panels on the completion of a particular 'step', instead of creating a whole new form for each step?

I know how to do this but everytime I create more than one panel, the controls from one panel end up going onto the panel behind the top panel. I know a groupbox would work for this but they are ugly (atleast in this situation). I can't seem to find any info anywhere else that may suggest that there would be another way of doing this.

thank you,
jay

Create a UserControl for each step in the process and add/remove those from your main form.

This is the basic approach for a wizard form.
- each step is on a panel
- sitting forward/back incriments or decriment the panel to be shown.

If you place all the panels on a group control, you can have a nice and pretty method to show the correct one:

private void ShowPanel(Panel panel)
{
    foreach (Control ctrl in groupBox1.Controls)
    {
        ctrl.Visible = (ctrl == panel);
    }
}

Do not start adding and removing controls on the fly; the problems outweigh any possible benefit.
