Hello rakesh,

Plz Build solution every time whenever you want to debug it. Becoz it is possible that debugger will take old build solution & may give message that original source may change.

Best of luck.

Simple XML Parsing?

Hi, i'm developing a smartdevice application and i'm trying to read in elements from an XML document that i created? I've looked around and found i'm slightly lost

<client>
<currentclient ID="01">
<clientTeam>Arsenal</clientTeam>
<clientName>Dave Dunn</clientName>
<clientPos>1st</clientPos>
<clientWon>0</clientWon>
<clientLost>0</clientLost>
<clientDrawn>0</clientDrawn>
</currentclient>
</client>

Is the XML document and currently i want to be to say take the value of clientTeam "Arsenal" and set the text on a label elswhere to the value.

<code>public void UserReader()
{
string Path1 = "/Program%20Files/SmartDeviceApplication4/User.xml";
XmlTextReader Reader = new XmlTextReader (Path1);

while (Reader.Read())
{
if (Reader.NodeType == XmlNodeType.Element)
{

if (Reader.LocalName.Equals("clientTeam"))
{
this.TeamTitle.Text = Reader.Value;
}

if (Reader.LocalName.Equals("clientName"))
{
this.ManagerName.Text = Reader.Value;

}
}</code>

Is what i had, but i really dont think its what i'm looking for - it compiles but the label values dont change. Cry | :((

Hi davedunn,

Try giving

this.TeamTitle.Text = Reader.ReadInnerXml();

insteadoff

this.TeamTitle.Text = Reader.Value;

Guess this will help you.

Thanks and Regards

Hi.

I'm having a little trouble getting this thing to work.

I have two tables Houses and People

Every "Person" belongs to a House, but only one per house is the "OwnerOfHouse".
So I made a colum named "HouseOwner" in the "House" table, which has the PersonID. And every person has a "HouseID_FK" which tells them to which house they belog.

SO here is the thing. I'm working with ADO.NET 2.0, and using BindingSource. So I have a BindingSource that has my Houses in a nice DataGridView, and when I click on any of them, I have another DataGridView which displays the people that live there.
That works Fine.

Now, when I chose one of the inhabitants, and press a button, His ID is updated on the Houses table, and I have a reference that tells me he is the Owner. So far so good.

What I want to do is that when I choose a House in my first DataGridView, The Owner is selected automaticlly in the People DataGridView. So far I've tried everything I could thinf of, but it allways selects the first element (the first person on the list).

Thanks in advance.

Once again, the only practical option you have is to rewrite the application from scratch. There are no steps to go through to convert the code! You have to write your own steps based on your own VB6 code!

Specifying range to the property in PropertyGrid

I'm currently developing some kind of editor by using the PropertyGrid. I saw in VS.Net that the property in PropertyGrid can be validated in range, I want to add that feature in my application also, but I don't know how.

Does anyone know anything about this ? Do it need to create new TypeConvertor ? Or just specify the attribute to that property ?

Hi

ProperyGrid control displays the properties collection for an object. For
each property in the propertygrid, its value can only be displayed in
string representation.

For a property that is build-in type, .Net has provided the
validation, while for custom type, we should implement the TypeConverter to
do the type convertion and validation.

Thanks and Regards

I would like to ask one more question.

What is displayed in the PropertyGrid Cells anyway, is it just take string from ToString() method, or using some mechanism to create the panel and display it there, etc ? And how can I customize the way it display property in the PropertyGrid.

Well, I means, what is espect to return from TypeConverter to use in PropertyGrid ?

I think it uses the output from TypeConverter.ConvertToString(). There are some other options in the TypeConverter class that can help you 'change' it a little.

I'll be very thankful,if someone lets me know the way by which I could convert a Visual Basic 6.0 project to C#.NET.
After migration, the code must produce the same results as seen in VB6.0.

That is not possible I think. You can convert from VB6 to VB.Net but even then you have to do some things manually.

The best solution is a complete rewrite, by hand, from scratch.

You COULD convert the app using the Conversion Wizard with VB6, then convert that code to C#. Chances are, you'll have to tweak a bunch of stuff by hand to get it to work in VB.NET, then you'll have to do a bunch of other things to get it to work in C#.

Use the upgrade wizard to convert to VB.NET. It's not perfect, but it can be done.

Once your code is in VB.NET you can easily convert to C# using either ours (Instant C#) or any other decent VB.NET to C# converter. There will be some manual adjustments, but nothing you can't handle (we offer support to help out with this also).

Built-in class for messagebox

Why would you want such a messagebox? WTF | :WTF:

It's not good UI design.

If you *really* think you want something like that, you can create a new form with no Ok or Cancel buttons and display your message there instead.

Cheers,
Vikram.

Hi I have almost finished an application in VS. I have tried releasing it a few times before to test it standalone somewhere else. I found that the files i have included into the solution will show up as xxx.deploy
Is there any way to make these files without the .deploy?

Also, i have created a mdb database file at design time. When i publish the application, it says it cannot find the mdb file at where it should be. A dialog box comes up and say

Error: 'C:\Documents and settings\Wallace\Local settings\Apps\2.0\A5mp6gt0.zcd\Database\database.mdb' is not a valid path. Make sure that .... blah blah blah

How can I fix it? should i not include the database as part of my application?

What should i do??? Confused | :confused:

Is the MDB file location the same on both your development machine and the target machine? I doubt it. You'd be better off without hardcoding the location of the database.

Vikram.
