How to retrieve File Information that store in server [modified]

22-Aug-06 22:22

If you're using a 3rd party control, they are by definition the best people to ask for help on how to use it.

Dear,
-I want to check the version of file then allow to download a updated-file automatically
-I had writen a function that allows to retrieve File information using FileInfo and FileVersionInfo
-It runs well if the source file 's in my local, but it was not functionly if the source file 's in the server.
Ex: http://www.misplacedcomedygroup.com/rss.xml
-And it also throws this exception: "URI formats are not supported."
Here is my function:

//function get version
public static string GetFileVersion(string srcFile){
string fileVersion;
try {
FileVersionInfo info = FileVersionInfo.GetVersionInfo(srcFile);
fileVersion = info.FileVersion;
}
catch (FileNotFoundException e) {
throw (e);
}
}

//function get last modify time
public static string GetFileLastAccessTime(string srcFile) {
string lastAccessTime;
try {
FileInfo file = new FileInfo(srcFile);
lastAccessTime = file.LastAccessTime.ToString();
}
catch (FileNotFoundException e) {
throw (e);
}
}

Thanks regards,
Germanrose

Hey,

Just wondering if you still need this, basically you will have to create a webservice/php script to return the information. It should work then.

Putting Components in Toolbox

Nested Partial Classes and Designer's

22-Aug-06 18:25

I can't seem to get my components to "automagically" turn up in the Toolbox. Once I put them there manually they are usually updated. Sometimes I'm forced to do a complete rebuild of the several projects within a solution, ensuring that before I do that I delete all the bin and obj directories. But that's a general problem, that's not related to specifically to Components, except that I have to add them all back into the Toolbox.

I seem to recall reading of a programmatic way to get things into the Toolbox, rather than the declarative method. the code that follows is one of the classes in question.

namespace ContextAnalyser.Technical
{
public partial class catDesignServices
{
[ToolboxItem(true)]
[DesignTimeVisible(true)]
[ToolboxBitmap(typeof(SplitContainer))]
[Description("Design Time Service - Exclude Properties and Events")]
[DisplayName("Property/Event Exclusions")]
public partial class catExcluder : Component
{
private catMemberSelector removeProperties;
[Editor(typeof(catDesignServices.catListEditorInitiate), typeof(UITypeEditor))]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
[DesignOnly(true)]
[Description("Items to be excluded from Properties Grid")]
[DisplayName("Excluded Properties")]
[Category("Design")]
[Browsable(true)]
public catMemberSelector RemoveProperties { get { return this.removeProperties; } }

Load excel to a dataset then fill this dataset to DB.

a sample code snippet from net:

       Dim ConnectionString As String <br />
<br />
        ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ <br />
                 "Data Source=e:\My Documents\Book20.xls;Extended Properties=""Excel 8.0;HDR=NO""" <br />
<br />
<br />
        Dim ExcelConnection As New System.Data.OleDb.OleDbConnection(ConnectionString) <br />
        ExcelConnection.Open() <br />
<br />
<br />
        Dim da As New System.Data.OleDb.OleDbDataAdapter("Select * from [Sheet8$]", ExcelConnection) <br />
        Dim ds As New DataSet("Workbooks") <br />
<br />
<br />
        da.Fill(ds, "Sheet8")

If I create a nested class based on Form or UserControl (see code outline at end of note) then VSE 2005 C# does not present a design surface with which I can work.

Same issue with Component based classes, although that's less of a problem as they tend to be less susceptible to change. Haven't tried DataSets but I assume they are the same. And there seems to be no way to nest Resource and Settings classes either. The rule seems to be that classes developed with designers cannot be nested.

Q1 What am I doing wrong (apart from daring to use nested partial classes)?
Q2 Is there a workaround?
Q3 Is it a VSE constraint, that's not manifested by other versions of 2005 VS C#.
Q4 If this is a common constraint, does that imply I could not create nested classes using the Class Designer provided in the Standard and Professional editions of VS 2005 C#.

myUserControl.cs
namespace myNamespace {
partial myOuterClass{
partial public class myUserControl : UserControl {
public myUserControl{
InitializeComponents()
}
}
}
}
myUserControl.Designer.cs
namespace myNamespace {
partial myOuterClass {
partial class myUserControl {
public myUserControl {
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
.
.
.
private LastGadgetType lastGadget;
}
}
}
}

1 - your control needs to be the first class in the file in order to show in the design view

2 - See 1

3 - Not that I know of

4 - yes, there is a common constraint there in how you organise classes if the deigner is to work.

Thanks Christian, your answers are as I expected, but not what I wanted to hear.

What's the point of including nesting and partial classes if the tools don't support them. Are there any other C# IDE's that do support partial nested classes -don't bothering answering that I can google too.

Are you aware of any plans by MS to support partial nested classes etc in their designers in future versions of VS. I guess I could always write my own, I'm not planning on doing anything this evening OMG | :OMG:

It's got nothing to do with it. Two vanilla classes will kill the designer, if your control is not the first one.

*grin* I don't need to. I doubt any other IDE is going to be better than the MS one.

No, I have no idea, and I doubt it's a priority.

Re: windows control panel

24-Aug-06 14:49

got another hammer out and did some panel beating - I can live with the result.

FYI I d'ld the ICSharp Open Source C# IDE, same problem. It's got a "prettier" editor, no data designer as far as I could make out. I does have better "out of the box" integration with "help system" and some documentation features, than I haven't seen in VS. And you get the source. Would I use it for life critical stuff, no, but nor would I use VS.

Turn off HtmlEncode in GridView

Hi,

I need to turn OFF the HTMLEncode property of a GridView Column dynamically i.e. when I'm reading from a Chinese database, i need to show "GB2312 Charset" characters.

I'm binding the GridView dynamically in code behind by its DataSource property. The only place where i could find access to the HTMLEncode property is when you explicitly create a Bound field (which i don't want to do). How do I turn off the HTMLEncode property of a Column in a GridView programatically??

Any help would be appreciated.

(if anyone knows how to display GB2312 characters in a Gridview by some other way ,that would be great too Smile | :)

)

Thank you
Sanjot.

email "To:" textbox control?

philxan22-Aug-06 15:32

22-Aug-06 15:32

Hello,

I need a textbox control that operates like the "To" control in many email programs, (Outlook etc). I've had a good look around, but can't seem to spot one anywhere. I know I've posted this in General Discussions, but haven't received a response there. Sorry for the cross post.

If you understand how the To: or CC: etc controls in an Outlook New Mail operates, then you've basically got the requirements right there. It displays a list of objects, each represented by some underlined text. You can select, double click on the object's text, and it will display more information etc. You can drag and drop them between two similar controls (eg. from To to CC etc). Most importantly, you can't split up the text of an object - to the user, the text IS the object

I've got a good start on developing such a control, but I'm concerned about the full amount of support required for it. For example, undoing, intellitext etc. etc.

Thanks in advance for any help or pointers

Phil

Changing icons in treeview (they aren't supposed to change!)

22-Aug-06 17:30

This is definately something you need to write yourself. Undo is easy, just keep a history of what the user types in a list Smile | :)

Re: Changing icons in treeview (they aren't supposed to change!)

22-Aug-06 14:10

Well i've almost go this treeview finished, it looks good now, got icons for different types of nodes, but when i click on a node, its icon gets changed to that of imageindex 0, and when i click another it changes back.

I don't know why it's doing this, but is kind of annoying, its not a priority or anything so...

Re: Changing icons in treeview (they aren't supposed to change!)

22-Aug-06 14:38

Well i got this:

void TreeView1AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
this.treeView1.SelectedImageIndex = this.treeView1.SelectedNode.ImageIndex;

}

but it redraws the whole treeview (redraw, not rebuild) with a nasty flash, every time the SelectedImageIndex is changed, any way around this?

or do i just have to find another icon for the SelectedImageIndex?

Hello

You should set the images when initializing the treeview for the first time only, not every time you select/unselect a node. Do this in your form's constructor, or the Form_Load event handler.

Besides you set the TreeNode.SelectedImageIndex, not TreeView.SelectedImageIndex. The latter is the default image displayed for any selected node, if the node doesn't have an images -will work fine if you have only one image for all selected nodes-.
