Hello,
I am using SQL Server Everywhere and today I have found SQLite by google search and got confused thinking that, "SQLite could be better...". Do any one has any opinion about comparing these two embedded database solutions ?

Firebird is the best embedded database I've found if you want SQL language compatibility.

Hello,
I was wondering if anyone know how to put dropshadow on a usercontrol. I had a windows form, and used CreateParams (like this: http://davidkean.net/archive/2004/09/13/151.aspx), which works perfectly. Unfortunately this doesn't work when I changed the form to a usercontrol.
I know I can draw the shadow myself, but my question is if there is some "simple" way to get dropshadow on a usercontrol.
Best regards,
Jan-Erik Romøren

How do i de install .NET framework 1.1 and re install it. i have .NET framework 2.0 on the same machine and its a windows 2003 server.
How do i do it
|
|

|

I suspect some thing is messed up with the .NET 1.1 and so i want to reinstall that
The reason i came to that conclusion is that a .NET application i wrote previously which was working previously well is now generating an error
"Application has generated an exception that could not be handled process id = .... Thread id = .... "
The same application works perfectly on my computer and i know that it worked perfectly two days before too on one of our customer computer and some thing was done on that server afterwards.
Well i want to know if there is an easy way to remove it and reinstall it its on windows 2003 server. It does not show up in Add Remove Programs. When i just run dotnetfx.exe(redistributable package) it says its already there.

lo,
im sending data form com1 to com2, these are all strings;
now i want to send for example name and adress together, so i send them with a marker:
port.WriteLine("1" + txt_name.Text);
port.WriteLine("2" +txt_adres.Text);
on the reciever site i need to put the received string in an array so i can check the first letter, if this is an 1 i can show it in textboxname, is it 2 in textboxadres
how do i put the string recieve, in an array ?
thx

hi,
you can send your string in comma separated way
for ex.
port.WriteLine("1" + "," + txt_name.Text);
and while receiving it you can split string on comma delimeter and store it in array.
for ex.
string []strarr=strGetString.Split(',');
where strGetString is a string variable in which you receive string data.
hope this works.

thxx
but how do i check on 1 and 2
i think strarr[0] contains "1" and strarr[1] the rest of the text right?
so do just do this:
string strGetString = ReadLine();
string[] starr=strGetString.Split(',');
if (strarr[0]=="1")
{
textboxname.text = starr[1];
}

hi all,
I have a xml file like this
<code>
<?xml version="1.0" encoding="utf-8" ?>
<app-settings>
<sqlconnection string="sql" />
<generate-interval value="" />
<monitors>
<file filename="test.file" />
</monitors>
<templates>
<template xsl="hello1.xsl" outputhtml="hello1.html" xmldata="hello1.xml"
sqlquery="select top 10 * from table1"
linkurl="http://www.test.com/query.aspx?linkid=%aa%"/>
<template xsl="hello2.xsl" outputhtml="hello2.html" xmldata="hello2.xml"
sqlquery="select top 10 * from table1"
linkurl="http://www.test.com/query.aspx?linkid=%aa%"/>
</templates>
</app-settings>
</code>
then I want get and modify the app-settings/monitors/file attribute like 'filename'.
how to do it?
I tried this code, but it doesn't work.
<code>
XmlDocument doc = new XmlDocument();
XmlNode node = doc.SelectSingleNode("/app-settings/templates/template");
if (node != null)
{
Console.WriteLine("ok");
}
else
{
Console.WriteLine("error");
}
</code>
Thanks for your help.

I forgot this
<br />
doc.Load("123.xml");<br />

First of all "it doesn't work." isn't very descriptive. So the next time explain in more detail what's wrong.
To modify the app-settings/monitors/file node you should select it:
XmlNode node = doc.SelectSingleNode("/app-settings/monitors/file");

There is no any exception in my code.
It's just get a null object. and I didn't know why.
Then I found that I didn't 'doc.Load()' before use 'SelectSingleNode' method.

I am using Visual Studio 2005 and need some methods that are new in .NET2.0, but they don't show up in the code completion list. The one i am looking for is ListBoxt.RefreshItems(). How do I use this?
I have filled a lixtbox with objects that have a ToString() method. I am updating the output for the ToString() from a textbox, but the new text is not shown in the listbox. Does anyone know how to update the listbox without removing and re-adding all the elements?

Did you click on the All tab at the bottom of the Intellisense window? You can still use the method. The list is just being filtered, by default, showing just the most commonly used properties/methods/events of the object.
What do you mean it doesn't update? What does youe code look like that is doing the update?

Hi there !
I have nested XML data and exact schema definition
Example:
<LEVEL1>
<ELEMENT1>Text....</ELEMENT1>
<ELEMENT2>More....</ELEMENT2>
<LEVEL2>
<ELEMENT3>Text....</ELEMENT1>
<ELEMENT3>More....</ELEMENT2>
<LEVEL3>
<ELEMENT3>Text....</ELEMENT1>
<ELEMENT3>More....</ELEMENT2>
</LEVEL3>
</LEVEL2>
</LEVEL1>
The XML file can be read into a DataSet object. During xml parsing by the DataSet.ReadXml () function, relations are automatically added. ID Columns are also added for the nested data levels, so that they can be tracked back to the top element.
I would like to bind each level to a different DataGrid, using the relation, so that when an element of level one is selected in the first datagrid, only the contained elements are displayed in the second datagrid, and so on. This requires at least two levels of relations that seem not to work with normal databinding., because the relations are only between two tables and as far as I found out I can not create a relation between two relations.
Please help, maybe there is a better way to display data like that with standard GUI components.
thanks
Christian

Hi,
I am having a ListView component in my WinForm, when i add some images into it, it gives me a vertical scroll bar.
What i want is, the horizontal scrollbar instead of vertical.
Is there any way to hide the vertical scrollbars and display horizontal scrollbars?

I have a function GetVersion() that returns the version (e.g. 1.0) and I want to achieve this:
When I do MessageBox.Show(GetVersion()) to display 1.0 as a version.
When I do MessageBox.Show(GetVersion().Major()) to display 1
and when MessageBox.Show(GetVersion().Minor()) to display 0.
Parsing isn't issues here, but how to implement this GetVersion().SomeMethod().
I have tried this with the class with its methods:
public SomeClass GetVersion()
{
}
But this function required to return a value od type SomeClass and I need a string to return.
I don't know how to return a string with GetVersion() becouse GetVersion is type of SomeClass.
Or I can try by inheriting the Strings class and implement those two functions in that inherited class?

Your GetVersion() will need to return a type that implements GetMajor and GetMinor itself. Here is an example:
class VersionInfo
{
public int Major
{
get { return major; }
set { major = value; }
}
public int Minor
{
get { return minor; }
set { minor = value; }
}
private int major;
private int minor;
public override string ToSting()
{
return major + "." + minor;
}
}
class SomeClass
{
public static VersionInfo GetVersion()
{
VersionInfo temp = new VersionInfo();
temp.Major = 1;
temp.Minor = 0;
}
}
You can then use SomeClass.GetVersion() to get a VersionInfo , or SomeClass.GetVersion().Major or SomeClass.GetVersion().Minor
I modified your GetMajor() and GetMinor() functions to use properties. It's the preferred way in C# to access attributes of a class.
