Updates to callconvutil.cs for .NET 2.0

Anyone else out there started to mess with Python.NET on the 2.0 platform? One of the first hurtles was the output from ildasm does not always place the method name on the next line, causing callconvutil to place the modopt in the wrong place. I've added a regex in to check for and split the method line if the function name is found.

PythonNet and .NET Framework 2.0
by Aaron Stubbs 20 সেপ্টেম্বর, 2005

Is there any way to use PythonNet with the 2.0 version of the .Net framework? The assemblies we're working with will for the test harness we're creating will all be .Net 2.0 assemblies, so if there's anything we can do to get PythonNet working with them I'd be all ears. I did note that this will be a specific feature (as outlined by Brian) for the PythonNet 2.x releases, but that appears to be a little way off... Thanks in advance for you time. Aaron

I've added a regex in to check for and split the method line if the function name is found. Currently getting lots of access violation exceptions. mike Replace ReadMethod with the following: public void ReadMethod(string line) { Regex findMethod = new Regex(@"^(\s*.method\s.*\s)([^\s()]+$[^()]*(?:,|$\s.*))$"); ArrayList lines = new ArrayList(); string mline = line; string data; string buff; while ((data = reader.ReadLine()) != null) { buff = data.Trim(); if (buff.StartsWith(ccAttr)) { // BUG: mline may have method name in it already which breaks // things. This is mostly seen in .NET 2.0. // Example: .method public hidebysig static int32 tp_descr_set(native int ds, if (findMethod.IsMatch(mline)) { // method name is on same line as .method. Need to insert // modOpt prior to method name. Match match = findMethod.Match(mline); writer.WriteLine(match.Groups[1].Value + " "); writer.WriteLine(modOpt + " "); writer.WriteLine(match.Groups[2].Value); } else { writer.WriteLine(mline); writer.WriteLine(modOpt); } WriteBuffer(lines); writer.WriteLine(data); return; } else if (buff.StartsWith("} // end of method")) { writer.WriteLine(mline); WriteBuffer(lines); writer.WriteLine(data); return; } lines.Add(data); } }

winForms, threading and dragdrop ?
by Guy Robinson 12 সেপ্টেম্বর, 2005

12 সেপ্টেম্বর, 2005

From the attached code.With AllowDrop = True I get a .NET error as follows: System.InvalidOperationException: DragDrop registration failed. ---> System.Threading.ThreadStateException: The current thread must set to Single Thread Apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. From googling I need to set ApartmentState.STA. But this is readonly. How do I set STA correctly in Python for .NET?

binding python objects to treenodes
by Guy Robinson 11 সেপ্টেম্বর, 2005

11 সেপ্টেম্বর, 2005

Hello, Is there a way to bind a python object to a treeView node? I have the following treenode based class: class dataNode(WinForms.TreeNode): def __init__(self,name,total): self.Text = name self.Total = total And I add the node as such: self.treeView1.Nodes.Add(dataNode("testnode",3)) But when I try and access the attributes it doesn't work? for node in self.treeView1.Nodes: print node.Total Or should I keep the nodes in a list and access by index? Any help appeciated. Guy
