Hi guys,
we developed a object persistent framework for .net and posted it at sourceforge as GPL (Url: http://www.sourceforge.net/projects/opfnet/). I don't know if somebody out there wants to check out our library in his own applications. You are welcome to use it in your open source projects and to give us a feedback - if you want!
We posted also a tutorial on the page. As it is not so easy to understand a thing never used before without tutorial.
Perhaps somebody likes it. It would be cool to get feedbacks.
Thanks and bye bye.
Christian

I have a weird problem to solve -- is there a way to turn an already compiled MDI application into SDI. It doesn't have to be a perfect solution -- it can be a manual process. For example, if I can get a list of MDI child winodws in the MDI, then have a button for me to manually make a MDI child window into a SDI window, that will be enough for me.
Any help will be greatly appreciated.

I think you can simply set the MDIParent property of each child window to null at runtime:
foreach(Form f in this.MdiChildren)
{
f.MdiParent = null;
}

Hi. I am transferring an XML file to another PC's shared folder. I tried to use a File.Copy method but the XML file that has been transferred to the other pc becomes garbage. Is there another way of transferring the file that it won't become garbage?
I used the ff code:
File.Copy("\\\Data\\" + FileName, true);
Where Data is a shared folder. The file got there alright but the content is just garbage. Please help.

I would suspect that something else is going on since that code should work. It's not as if the operating system treats XML files differently than other files when copying them. I'd play around a little to try and discover what's occurring.

good day,
hi i have the application consists of Webservices, COM+, and a client all written in c# .net, and all in different machine. In webservices computer i have the application proxy of com+ deployed(exported from com+ server computer) and reference it on the my web service, and on the client machine i have the web reference to my web service.
My problem is i cant access the com+ server from the webservice, it return an error "ACCESS IS DENIED", but when the com+ server and webservice(iis) is on the same machine, and i have the client accessing the webservice and of course the webservice accessing also the com+, it works fine.
If it is on the same host, no further work needed. If remote: export an app
proxy and install it on the webserver and the my webservice use that application proxy, it doesnt work.
How do I activate the COM+ components from other machines using webservice?
(using the COM+ export utility, remoting and etc.).
PLS HELP ME, thank and GOD BLESS

Hi,
I have build a C# application. It runs fine on my computer
Now I want to distribute this app to others. But some of the "others" do not have .NEt installed on their machine. How can I distribute "all" that is need for the app to run.
I am sure the good folks on this board would have come across this problem before and would have some solution/suggestions for me.
Thanks,
Suhas

Hi,
Yes there is a solution , I had the same problem as you, you can use the same tool that Visual Studio ships to Install your app, to include the .net framework, there is a trick, you have to take a look to:
Microsoft .NET Framework Setup.exe Bootstrapper Sample
That solution works, to make it more elegant you should pay $$$ and buy some professional tool, Wise or whatever, but this will work for you for 0 $

Hi,
I want ComboBoxes displayed in all columns of datgrid, always visible. And there are a lot of things in DataGrid that are difficult to resolve.
For ex, I always see one extra row at the bottom even when I have added the rows through DataTable and the DataTable.Row.Count is correct but Grid.VisibleRowCount is 1 greater.
Also, I don't want the column with readonly=true to be selected, whereas when I click on that column the background of that row becomes gray !
Any help would be highly appreciated  !
Thanks.

To disallow users from clicking or selected a particular column, you will have to use custom table style for your data grid. In this custom table style you will have to add custom data column styles - DataGridTextBoxColumn.
Derive a class from DataGridTextBoxColumn and in that override the Edit method and in that method do nothing.
public class MyTextBoxColumn : DataGridTextBoxColumn
{
public MyTextBoxColumn()
{
//
// TODO: Add constructor logic here
//
}
protected override void Edit(...)
{
if (!ReadOnly)
{
base.Edit(..); // call base class
}
//don't call baseclass, so no editing....
}
}
This should take care of it!
Hope this helps.

Hi Suhas,
I tried what you said but it's not working the way I implemented it. I'll explain what I did.
//Create a custom Column Style for the 1st Col: Questions
CurrencyManager cm = (CurrencyManager)this.BindingContext[dtTable];
PropertyDescriptor pd = cm.GetItemProperties()[0];//Get Prop for the 1st col
MyControls.MyDataGridTextBoxColumn myColStyle = new MyControls.MyDataGridTextBoxColumn(pd);
newGrid[indexPage].TableStyles.Add(dgdtblStyle);
newGrid[indexPage].TableStyles[0].GridColumnStyles.Add(myColStyle);
And to create the MyControl Class:
public class MyDataGridTextBoxColumn: DataGridTextBoxColumn
{
public MyDataGridTextBoxColumn(PropertyDescriptor pd) : base(pd)
{ }
protected override void Edit(CurrencyManager cm, int rowNum, Rectangle bounds, bool readOnly)
{
MessageBox.Show("in Edit");
if (!readOnly)
base.Edit(cm, rowNum, bounds, readOnly);
}
}
But that MessageBox is bever clicked & nothing diff happens when I try to edit the 0th Col !
What do you think I am doing wrong ?
Thanks.

Hi,
I put a label on top of that column in the data grid & now u cannot edit the text in that column. But if u click on any editable control like combo box in the datagrid, or even at any place in the grid where there are no rows, the first row gets selected ... What's happening !?!
I was able to remove that extra row with AllowNew property set to false.
Thanks for all ur help. But I think we need a much stronger DatagRid than what we have right now !

Add custom column styles to the custom table style AND then add the custom table style to the datagrid's table style collection. If you do the reverse, the way you have done, the data grid will not use your column styles

To see ComboBox in DataGrid always - try to override Paint method in suhass'es example. To avoid extra row set DataGrid ListManager protected property:
(DataView)(myDataGrid.ListManager.List).AllowNew=false;

I was able to avoid that extra row the way you said.
Is there a way to have Vertical Scrolling on in a DataGrid ?
Thanks

I am wanting to create my own "Item" for use in the "File|Add New Item" dialog window. Does anyone know of any resources which would point me in the right direction?
FYI: The item I want to create is an option to add a StronglyTypedCollection class.
Thanks.

Hi all,
In my project, i'm using a third party ActiveX component.
Right clicking the component during runtime will display a popup menu.
My problem is that i want to disable it ( or disable some of the options in the menu). Is it possible ?
