am able to get the whole content by querying
string sqlstring = "SELECT * FROM temp.txt";<br />
string sConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\Shared\ExportAndDisplayData\;Extended Properties=Text;";<br />
OleDbConnection objConn = new OleDbConnection(sConnectionString); <br />
objConn.Open();<br />
OleDbCommand objCmdSelect = new OleDbCommand(sqlstring, objConn); <br />
objAdapter1.SelectCommand = objCmdSelect; <br />
DataSet objDataset1 = new DataSet();<br />
objAdapter1.Fill(objDataset1, "Test"); <br />
DataTable dt1 = objDataset1.Tables[0];
Thanks in advance

call this function when delete record
function pagecount()
{
if(dgDocument.CurrentPageIndex >0)
{
dgDocument.CurrentPageIndex=dgDocument.CurrentPageIndex-1;
}

{
dgDocument.CurrentPageIndex=0;

What is your problem or question?

Is there any way to read the file that a .lnk (shortcut) refers to? Opening the file in Notepad shows that it is not plain text (such as Adobe Gamma Loader.lnk which loads Program Files\Common Files\Adobe\Calibration\Adobe Gamma Loader.exe). I am wondering if there is any way to read a .lnk file's location using some sort of library.
Thanks,
Josh

You can use the Windows Script Host Object Model COM library for this. If you're using Visual Studio, add a reference to it by selecting the COM tab from the Add Reference dialog and select "Windows Script Host Object Model". This will create an interop assembly called Interop.IWshRuntimeLibrary and will reference that. Then you can use the following code to extract the target file from a .lnk file...
<span style="color: blue;">using</span> IWshRuntimeLibrary;
...
WshShell shell = <span style="color: blue;">new</span> <span style="color: teal;">WshShell</span>();
<span style="color: teal;">IWshShortcut</span> link = (<span style="color: teal;">IWshShortcut</span>)shell.CreateShortcut( linkPath ); <span style="color: green;">
<span style="color: teal;">Process</span>.Start( link.TargetPath ); <span style="color: green;"> Hope that helps

Hi, do you use AxWebBrowser? If yes then webBrowser.Navigate("some.mht", ...) will do this work.

I have a custom control that has a StringCollection property:
private StringCollection _images = new StringCollection();
[Category("_Hotspot"),
TypeConverter(typeof(StringCollectionConverter)),
EditorAttribute("System.Windows.Forms.Design.StringCollectionEditor, System.Design", "System.Drawing.Design.UITypeEditor, System.Drawing")]
public StringCollection Images
{
get {return _images;}
set {_images = value;}
}
I want to be able to edit it at design time, so I wrote a type converter to translate it into a string and back in the attribute:
public class StringCollectionConverter : TypeConverter
{
public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType)
{
if (sourceType == typeof(string))
return true;
else
return base.CanConvertFrom(context, sourceType);
}
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
if (destinationType == typeof(StringCollection))
return true;
else if (destinationType == typeof(InstanceDescriptor))
return true;
else
return base.CanConvertTo(context, destinationType);
}
public override object ConvertFrom(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value)
{
if (value is string)
{
string[] v = ((string)value).Split(new char[] {','});
StringCollection stringList = new StringCollection();
for (int i=0; i<v.Length; i++)
{
stringList.Add(v[i]);
}
return stringList;
}
return base.ConvertFrom(context, culture, value);
}
public override object ConvertTo(ITypeDescriptorContext context, System.Globalization.CultureInfo culture, object value, Type destinationType)
{
StringCollection stringList;
if (destinationType == typeof(string))
{
stringList = (StringCollection)value;
string result = "";
for (int i=0; i<stringList.Count; i++)
{
result += stringList[i];
if (i < stringList.Count - 1)
result += ",";
}
return result;
}
else if (destinationType == typeof(InstanceDescriptor) && value is StringCollection)
{
stringList = (StringCollection)value;
ConstructorInfo ctor = typeof(StringCollection).GetConstructor(new Type[] {});
if (ctor != null)
return new InstanceDescriptor(ctor, new object[] {});
}
return base.ConvertTo(context, culture, value, destinationType);
}
}
I'm able to click the elipse in the editor, bring up the string collection editor, and enter strings. The strings are written out properly as a comma delimited list in the attribute of the control, but when I run the app, those values are never initialized into the string collection at runtime.
This seems like a lot of work to have a simple collection of strings as a property. Does anyone know how to make this work? I've been searching the web trying to figure this out for days. Lots of people ask about it, but no-one really seems to have the answer. Thanks.

Hi,
you would have much less work to change your property to type string[] . This one is fully supported by the IDE. If you still need the collection you could just make a second one which just acts as a wrapper for the designer and internally modifies the collection.
|
|
|
|
|
If I try to use string[] for the property, after I populate it in the editor at design time and switch to look at the source, it writes the attribute as "String[] Array". What do you mean, it's fully supported by the IDE?
|
|
|
|
|
Yes it is. The TextBox has a Lines property which behaves exactly the same way. Notice the little '+' left of the text 'String[]-Array'? Click it you'll see all single elements of the array.
|
|
|
|
|
There's no + sign next to the property in the property grid. There is an elipse to the right of it that brings up a "String collection editor," which I did not specify.
Like I said before, it writes 'String[]-Array' as the attribute for the property in the SOURCE CODE of the page. The strings themselves do not get recorded properly in the source of the page.
I'm using VS 2005, if that makes a difference.
I'll try adding a typeconverter, but I feel like I'm just going back down the same road I took with the StringCollection type.
Edit: After I populate the array in the string collection editor, I do see a + next to the array in the editor, as you said. But it still doesn't populate it in the source properly.
Edit: I got it working! It turns out there's a prebuilt type conerter for string arrays, and I just had to specify it above the property:
TypeConverter(typeof(StringArrayConverter))
Now everything propagates properly. Thanks for the advice!

The only thing I can think of is that this somehow behaves different in web application (I don't know why it should though). I've just tested it for a winapp and it works...

You can put any window inside another.
use SetParent.
You could show Notepad's window inside you button if you wanted.

I am doing some development work with a login page passing a
Session["name"]= this.txtLogin.Text;
Session["Program"] = "PromoLeads";
Response.Redirect(url.ToString());
The database returns 1 or 0 based if the password and user matched. However this will not work with IE 6.0 on a Windows 2003 Server IIS. But it will work on a Windows 2000 IIS. If I use firefox it works fine regardless of what server its going to.
My question is, is there a setting on the IIS server (W2003) that I am over looking?
Thanks

Through reading forums and pages. My server name has an _ (Underscore) in the name, there seems to be some sort of bug with that based on a security property.
The options to fix this is use the IP address for the server instead of the name or rename the server if thats an option. There are other options as well, however, this was the easiest.
