I've been playing with Reflector recently (just out of interest of course  ).
It seems to disassemble my VS projects fine. But when I try it on commercial assemblies (such as ITunes or something similar) I get an error saying that it could not find a command line interface.
Could anyone explain why this is so? Is it do with the language it was written in?
Mark.

I suspect ITunes is not a .NET application.

It is to do with what it is compiled to rather than what it is written in. If it is compiled to CIL (sometimes known as MSIL) Reflector will work - because that's what it is reflecting on. If it is a native DLL then it won't.

Hi,
I am getting to where I need to be, but slow going, and thanks for all of the previous help.
What I have so far...
Form loads and checks to see if xml file exists, if it does, it loads into runtime dataset and binds to datagrid:
CODE
private void Form1_Load(object sender, EventArgs e)
{
try
{
//File.OpenRead("C:\\DriveData.xml");
DataSet ds1 = new DataSet();
ds1.ReadXml("C:\\DriveData.xml");
dataGridView1.DataSource = ds1;
dataGridView1.DataMember = "DriveInfo";
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
finally
{
Console.WriteLine("Use the Open File button.");
}
}
On the form, if the datagrid is not populated, the user can load an excel file:
CODE
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "Excel (*.xls)|*.xls";
openFileDialog1.InitialDirectory = @"C:\";
openFileDialog1.FilterIndex = 2;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog(this) == DialogResult.OK)
{
using (System.Data.OleDb.OleDbConnection objCon = new System.Data.OleDb.OleDbConnection(string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\";",
openFileDialog1.FileName)))
using (System.Data.OleDb.OleDbCommand cm = new System.Data.OleDb.OleDbCommand("Select * From [sheet1$]", objCon))
using (System.Data.OleDb.OleDbDataAdapter da = new System.Data.OleDb.OleDbDataAdapter(cm))
{
DataSet ds1 = new DataSet();
objCon.Open();
da.Fill(ds1,"DriveInfo");
objCon.Close();
ds1.WriteXml("C:\\DriveData.xml",XmlWriteMode.WriteSchema);
ds1.ReadXml("C:\\DriveData.xml");
dataGridView1.DataSource = ds1;
dataGridView1.DataMember = "DriveInfo";
}
}
}
This works great, but the part that I thought would be easier is harder for me at least.
I have a strong typed dataset created in my vs project with one datatable.
This dataset is part of the same initial form that loads and is binded to textbox, and other type controls.
I also have the binding source and binding navigator components at the bottom of the design screen for this dataset.
Here is what I want to do...
I want to write the strong typed dataset to an xml file, just like the weak typed one before, and then reload the xml file back to the dataset, maybe this step is not neccessary until I have changed data.
Anyway, I want this dataset editable/updated as if it were connecected to a dataadapter that was connected to a database.
My Save Button is greyed out on the binding navigator.
When I save changes, I want to have them save to the xml file, so that even if the application closes, the changes will be there.
Thanks, sorry for long winded.

Hi all,
I have a Share Point server when i installed a windows service that use "remoting" technology - using IpcChannel. From the local machine everything work fine: i opened a website from the ie browser and when the SharePoint's server executed the code from OnInit method everything works fine (SharePoint server gets the proxy from Windows Service and wrote some results in a text file). The problem appears when i tried to access a website from another machine (other than the machine where i installed the windows service): so in OnInit method i initialized the remoting (create the IpcChannel, register the channel and i got the proxy object but when i tried to call a method from proxy object i received the following error message: Failed to create an IPC Port: Access is denied. I think that the problem is about the user security but i can't find the problem 
Thanks a lot

I am really turning nuts!
I have the following problem: I have a library that is MTA by design - and I cannot modify it, I have only the assambly. So far so good, but my application is a WPF application. And that in turn is STA by design.
So my simple question: How can both talk to each other? More precisely, there are no problems unless callbacks from the MTA-library are executed. I would like to give some feedback through the GUI, but nothing happens (ok, at least there is a caught exception that the GUI an only be modified from a STA thread... fine, so my delegate is still executed out of some library's thread)
The simple delegate does not work, implementing a wrapper with some event does not either. Posting a "real" Windows Message and grabbing data out of the wrapper would work, but that cannot be the best answer for my problem... can it??
Any help appreciated to make my code some kind of more professional.

When you get a callback from the MTA library, just post to the Dispatcher of your WPF app to do the UI-related work. See MSDN's WPF Threading Model[^] for more info.

You are my man! Thanks a lot, that was it! The Dispatcher... argh, of course.

Thank a lot, but Judah's post gave me already the answer I searched for. (And it was about the same as the German page was about)

I am wondering is there a way not to repaint/redrawn an item while scrolling up and down in listbox. I want to eliminate heavy repaint. I couldn't find any resource that to cache these items.
Thanks

hey can anyone can please help im new to c#, im trying to add a button to my program that will make a copy/backup of a file, the location of the orignal file is static so no need for dir listboxes. the problem i have is when it come to creating the copy.
private void button1_Click(object sender, EventArgs e)<br />
{<br />
folderBrowserDialog1.Description = "Select a Directory to Back up the Database";<br />
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)<br />
{<br />
System.IO.File.Copy("c:/test.txt", folderBrowserDialog1.SelectedPath + "UNKNOWN.txt", true);<br />
MessageBox.Show("File saved to " + folderBrowserDialog1.SelectedPath, "Backup Made", MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
}
any help would be great 
|
|
|
|
|
I'm not getting any syntax error, however the file isn't copying if SelectedPath doesn't have a slash at the end.
+ "/UNKNOWN.txt" is a quick fix but you'll be better off testing the last character of the SelectedPath and appending the slash so you don't end up with two slashes if a root folder is selected.

Hi,
I'm coding a Windows Service (using the Service Project in VS 2005) and in some occasions I would need to terminate in a clean way the service from inside of the code. In OnStart I create a worker thread, and I need this thread to, somehow, terminate the service. What is the best way to do it?
Thanks,
Federico
