You can add a few keys to the registry:
Under HKCR add a key with the name of your extension, for example ".mef" (my encrypted file).
Add a subkey "Shell", a sub-subkey "Open" and a sub-sub-subkey "Command".
Set the standard value of the new "Command" key to the program you want to execute, for example "notepad %1".
So now you should have:
HKCR
+--.mef
+--Shell
+--Open
+--Command (Standard) "notepad %1"
Explorer will show the icon of the application (notepad in our example) and open notepad when you doubleclick a .mef file.

I have a program I am writing for my own personl use that takes an XML file and interprets it into a treeview, then if a secion is clicked it shows the information between the tags in a textbox. The problem im having is with this peice of code.
XmlTextReader document = initializeXmlReader();
while((document.Name != e.Node.Tag.ToString()) && (document.GetAttribute("Name")!= e.Node.Text))
{
document.Read();
}
All the tree nodes are made up of the elemets attributes, this code works partially to go through the document and find if the right attribute, but sometimes it returns null, and does not display the next catagory's text.
Here is some sample XML.
<?xml version="1.0" encoding="utf-8" ?>

I've been testing it by just clicking the first few treenodes that have a different attribute. But most of the time only one or two will work before it is just stays on the same thing for anything else I click. This is really bothering me. I edited out the text that was inbetween the tags, for length problems in this posting.
Sample of what its doing.
Tree
Desktop Sidebar
--OverView
---Context
---Options
--BasicPanels
---Communication
----Mail Checker Panel
----Messanger Panel
----Miranda IM
and so on
When I click mail checker panel for instance, it will show up right. But then if I click messanger Panel, it will show up with Main Check Panels text instead of Messanger Panels Text, upon debugging I noticed that getattribute is returnning null sometimes, I beleive this is the problem. The text between the tags will, contain HTML which is parsed by the textbox/web browser i've incorpertaited.
Any help would be much apperiated. Also if more code is needed I can post it.

Hello everyone,
I have a problem with Encrypting and Decrypting files. I read an article about it at the Microsoft-Homepage but this example works only with text files and I want to encrypt and decrypt every file type.
http://support.microsoft.com/default.aspx?scid=kb;EN-US;307010[^].
Maybe the problem is Encoding.
Please help me!

Actually, the encrypt function will work with any file type, but the decrypt function might not. StreamReader and StreamWriter are to help with reading/writing text from/to streams, so you don't want to use them in this case.
The example code there isn't very efficient for large files either, since it reads in the whole file at once, and your memory will be stuffed.
Here's a more practical version of the last section of the EncryptFile function:
<br />
byte[] buffer = new byte[1024];<br />
int len;<br />
<br />
while((len = fsInput.Read(buffer, 0, buffer.Length)) != 0)<br />
{<br />
cryptostream.Write(buffer, 0, len);<br />
}<br />
cryptostream.Close();<br />
fsInput.Close();<br />
fsEncrypted.Close();<br />
And here's the last 5 lines of the DecryptFile function, works for any file type and file size:
<br />
byte[] buffer = new byte[1024];<br />
int len;<br />
FileStream fsDecrypted = new FileStream(sOutputFilename, FileMode.Create);<br />
while((len = cryptostreamDecr.Read(buffer, 0, buffer.Length)) != 0)<br />
{<br />
fsDecrypted.Write(buffer, 0, len);<br />
}<br />

I get this error message when I use the Update oleDbCommand in my program. I cannot find the word 'DEFAULT' in any of my code. What does it mean?
Thanks

Did you toggle all outlining before you search for the text "DEFAULT"?
If so, please submit some code here (especially the line(s) the exception is thrown so we can help you.

Yes I did toggle outlining. Here is thae code for update...
public void UpdateDataSource(FinalSiteSafetyPlanBuilder.dsBuildPlan ChangedRows)
{
try
{
// The data source only needs to be updated if there are changes pending.
if ((ChangedRows != null))
{
// Open the connection.
this.oleDbConnection2.Open();
// Attempt to update the data source.
oleDbDataAdapter6.Update(ChangedRows);
}
}
catch (System.Exception updateException)
{
// Add your error handling code here.
throw updateException;
}
finally
{
// Close the connection whether or not the exception was thrown.
this.oleDbConnection2.Close();
}
}
public void UpdateDataSet()
{
// Create a new dataset to hold the changes that have been made to the main dataset.
FinalSiteSafetyPlanBuilder.dsBuildPlan objDataSetChanges = new FinalSiteSafetyPlanBuilder.dsBuildPlan();
// Stop any current edits.
this.BindingContext[dsBuildPlan,"BPlan"].EndCurrentEdit();
// Get the changes that have been made to the main dataset.
objDataSetChanges = ((FinalSiteSafetyPlanBuilder.dsBuildPlan)(dsBuildPlan.GetChanges()));
// Check to see if any changes have been made.
if ((objDataSetChanges != null))
{
try
{
// There are changes that need to be made, so attempt to update the datasource by
// calling the update method and passing the dataset and any parameters.
this.UpdateDataSource(objDataSetChanges);
dsBuildPlan.Merge(objDataSetChanges);
dsBuildPlan.AcceptChanges();
}
catch (System.Exception eUpdate)
{
// Add your error handling code here.
throw eUpdate;
}
// Add your code to check the returned dataset for any errors that may have been
// pushed into the row object's error.
}
}
Here is the click event code.....
private void btnUpdate_Click(object sender, System.EventArgs e)
{
try
{
// Attempt to update the datasource.
this.UpdateDataSet();
}
catch (System.Exception eUpdate)
{
// Add your error handling code here.
// Display error message, if any.
System.Windows.Forms.MessageBox.Show(eUpdate.Message);
}
this.dsBuildPlan_PositionChanged();
}
Thanks,
Mark

Don't you get the line where the exception is thrown?
I'm not sure but you might want to check the method UpdateDataSet and the line "this.BindingContext[dsBuildPlan,"BPlan"].EndCurrentEdit();"

Thanks, I checked that line and it looks good. I think Dave may be on to something regarding the SQL Update Command Text.
Mark Garcia
|
|
|
|

The problem is not in your C# code, at least not directly. The syntax that it's talking about is the SQL command that the Update method is trying to execute.

Well, I have no idea. But I would suspect and start researching the possibility that you've either hit a statement length limit or a limit on the number of parameters, or a limit on the complexity of the statement. You could get away with something like this in SQL Server. I'm not so sure about the Jet database engine.

I have a windows form and the first thing I want to happen is for a MessageBox to ask a Yes/No question after the form loads. However, I want the form to fully render itself before the MessageBox pops up. If I put the MessageBox.Show in the form constructor or in the form's Load method, the MessageBox appears first thing and the form does not appear until the user answers the MessageBox.
What do I need to do?
Thanks,
Mark Mokris

Hello,
Maybe you could call the Form's Invalidate method before showing the messasge box.
Peter
|
|
|
|
|
Is the form supposed to wait on the message box to do something? If not, you can create a thread to show the message box. This will assure that your app will paint itself in the background. Make sure the messagebox is on top though.

I am trying to write then read my first XML file. It is meant to store settings for a device. The user will store stuff to the file, then maybe load it back and transmit it to the target board. Sounds pretty simple.
My question is how to parse this guy. How do I get the data back out so I can plop it on the forms I've created? I see how to rifle through the file, but now how the heck to see where I am. I'm very new to this, so a real-world example would be great.
Here's how I'm setting up to do the read.
StreamReader stream = new StreamReader(fi.FullName);
XmlTextReader reader = new XmlTextReader(stream);
XmlSchemaCollection schemaColl = new XmlSchemaCollection();
schemaColl.Add(null,"XMLSchema_LCData.xsd");
XmlValidatingReader valReader = new XmlValidatingReader(reader);
valReader.ValidationType = ValidationType.Schema;
valReader.Schemas.Add(schemaColl);
valReader.ValidationEventHandler += new ValidationEventHandler(valHandler);
while (valReader.Read())
{
// Now what? How would I know that I have some certain piece of data?
// Pretend I want to know that is the FINV0 for CreepB from the XML file.

Use XmlDocument instead. Better performance for especially short XML files.
Here is an example:
<br />
private void Insert2XML(string strXmlFilePath, string PersonName, int ID, string Notes)<br />
{<br />
XmlDocument doc = new XmlDocument();<br />
doc.Load(strXmlFilePath);<br />
XmlNode root = doc.DocumentElement;<br />
<br />
XmlNode Person = doc.CreateElement("Person");<br />
Person.SetAttribute("Name", PersonName);<br />
Person.SetAttribute("ID", ID.ToString());<br />
Person.InnerText = Notes;<br />
root.AppendChild(Person);<br />
<br />
XmlTextWriter writer = new XmlTextWriter(strXmlFilePath, null);<br />
writer.Formatting = Formatting.Indented;<br />
writer.Indentation = 4;<br />
doc.Save(writer);<br />
writer.Close();<br />
}<br />
<br />
private string GetPersonID(string strXmlFilePath, string PersonName)<br />
{<br />
XmlDocument doc = new XmlDocument();<br />
doc.Load(strXmlFilePath);<br />
XmlNode root = doc.DocumentElement;<br />
<br />
XmlNode SearchNode = root.SelectSingleNode("//*[@Name='" + PersonName + "']");<br />
if (SearchNode != null)<br />
{<br />
return SearchNode.Attributes["ID"].Value;<br />
}<br />
else<br />
{return "Not Found!"}<br />
}<br />

The .NET TextBox control automatically provides a nice context menu that pops up when the user right-clicks in it with all the stuff expected, like Cut, Copy and Paste (and some surprising ones, like right-to-left selection, etc.). However, if you add a context menu component of your own you lose the one provided. Does anybody know a way to find and merge with the default menu? I've been trying to add an item to call a spell checker I've added to my project and don't want to have to duplicate all of the nice things the TextBox already provides on its default context menu... Any thoughts?
Thanks in advance for any help!
P.S. I posted this question in the .NET forum, too - I don't want to clutter up these boards with duplicates, but this area looked a bit more active so I thought I'd try here as well...
