You are really new dude Smile | :)

ok When u double click the file you see the source which is in XML. Look at the botton left corner of the page, there should be "DESIGN" mode, click that to view designer. If you want to see the code behind, you can right click and say View code.

Do some reading Smile | :)

Well its ok..youll learn!!!
Try to use the right click options as often as possible!!! ull easily find ur answers!!!

Smile | :)

first make sure u checked the checkbox place code in a separate file when u add new item in your web application..then press right click on the mouse, choose view code, that way will let u to go in *.cs file

This code generates following error:

Can anyone help me please?

You may need to add a reference to the NHIbernate namespace to your project. Is VS, use the project menu, add reference, and then, selecting the correct tab, select the NHibernate component and click OK.

Last time I looked, that's not a hbm.xml file.(hibernate mapping xml file).
You have to create a valid mapping file in xml for hibernate that tells hibernate which table this class is bound to, and to map up the different properties to columns.

Hi,

I have a problem how to bind our database data into a listview..is it the same way we bind the data into gridview?could someone give me an example?

Thank You

I'm sorry maybe my english is bad

for example:
I have a table name Contact in my database..and i want the data on that table to be show on a Listview..I already know how to bind it on a gridview, but i can't find a way to bind the data on a ListView..i use SQLServer 2005 Express Edition for the database

Thank You Smile | :)

Hi,

In ListView you will have to Enumerate the datasource and fill it. For example, if your datasource is a DataTable, you can write the following:

foreach(DataRow row in table.Rows)
{
ListViewItem item = new ListViewItem();
item.Text = row["Description"].ToString();
item.Tag = row["ID"].ToString();
//For other coulmns

items.SubItems.Add(row["OtherColumn"].ToString();
}

Hope this helps.

Hi Guys and Gals.

Well, I dont know if I am posting this at the right place. Hope I did so that I dont irritate anyone. My question is as follows. We have 2 databases. SQL (online) and Access (offline). I need to implement code in a windows application that will (on a click of a button) synchronize these two databases so that they are always xactly the same.

Does anyone out there know how to do this or at least where I can find code that will guide me please?

Help is greatly appreciated since this is rather urgent.

Regards,

Elizma

Off the top of my head, here is a rough idea of how to do it:

First thing to do is to make sure you have the same table schema in the databases, and secondly you'll want to load everything from the SQL (online) databases into a dataset, then lastly, dump the dataset into Access.

One thing I would do with the Access database, is to keep a timestamp field of the data records that get synch'ed in from SQL.

"I've seen more information on a frickin' sticky note!" - Dave Kreskowiak

My databases are already exactly the same with the same schemas the works. The problem is that users will work on the Access db when they are out of the office. When they return they need to upload the newly inserted information from Access to SQL. Then since there could be changes in the SQL DB, we need replicate the changes to Access.

Okay, like I mentioned at the end of my last post, have a timestamp and that can help you with the synch.

Hi,

I am trying to find a quick way to add 1 dimensional array into multidimensional array. For example:

<br />
object[] oneDArray1 = new object[10];<br />
object[] oneDArray2 = new object[10];<br />
object[] oneDArray3 = new object[10];<br />

Then, I need to add this array into 2D Multidimensional array.

<br />
object[,] twoDArray = new object[3, 10];<br />

The reason I need to do this is because I have a DataSet and I need to convert this DataSet to Excel Application.
Currently, I do the following:

<br />
oRng.Value2 = oDataTable.Rows[iRowIdx].ItemArray<br />

This code work if the Range is within single row. Now, if I have 1000 rows, this is process is very slow. It takes about 20 seconds to loop through the range and set the rows.

Alternatively, I could set the value of the range at one go. For example I want to set the value from Row #1 Column #1 to Row #1000 Column #1000, I must do

<br />
object[,] 2DMultiDimensionalArray = new object[1000, 1000];<br />
oRng = oSheet.get_Range("A1", "ALL1000");<br />
oRng.Value2 = 2DMultiDimensionalArray;<br />

In order to set the excel value at one go, I MUST convert each DataRow.ItemArray into MultiDimensional array. I need to add Single Dimensional Array into MultiDimensional array (NOT jagged array because I have try it and it throw an error).

An unhandled exception of type 'System.Runtime.InteropServices.SafeArrayTypeMismatchException' occurred in mscorlib.dll

Additional information: Specified array was not of the expected type.

Any help is greatly appreciated!

Thanks Smile | :)

Do you want to export a DataTable to Excel? I am asking, because I would then suggest to use instead of arrays two loops. An outer-loop to do your rows and a inner-loop to do your columns.

Much faster than arrays.

Regards,

Elizma

Hi Elizma,

Yes, I am indeed exporting DataTable to Excel.
Doing loop for each row and each column will be quick if the number of columns aren't big. Here, I am talking about about 1000+ rows by 1000+ columns.

Currently, if I do

for (int iRow = 0; iRow < dt.Rows.Count; iRow++)
{
   oRng = oSht.get_Range("A" + iRow.ToString(), strLastCol + iRow.ToString());
   oRng.Value2 = (System.Array)dt.Rows[iRow].ItemArray;
}

This code is about 30x faster than nested loop. In my PC this loop takes about 20 seconds where as nested loop (to set each cell) takes about 10 minutes.

However, if you set directly to MultiDimensional Array, it takes less than 1 second (and probably few seconds to add the 1D array into Multidimensional array).

I am starting to think that it is impossible to add 1D array to Multidimensional array without nested loop Frown | :(

Any other idea to speed up this process? Thanks for any input/help.

Cheers Smile | :)

Hope this[^] article will give an idea about the arrays.

Hi Satips,

Thanks for the link. But it doesn't answer my question Frown | :(

Hi,

I embedded windows media player 11 on a form, and I add a few files to the currentplaylist of it. like:
WMPLib.IWMPMedia m= wmp.mediaCollection.add(sFile);
wmp.currentPlaylist.appendItem(m);

I want this playlist "Repeat" forever. but the function "repeat/Ctlcontrols.repeat" is gone. How to do this????

I don't want to create my own timeline thread to check the duration by the way.
Also I could not use the StatusChange and PlayStateChange event, it is not recommended by MS.

thanks a lot in advance!!
