I think ur making a lot of mistakes in this... I'd recommend that you go thru a few walkthoughs on MSDN and next time plz take the time to tell us about ur platform. like C# 1.1,2.0 ... SQL Server 2000 uknow!

by the way you're not ExecutenonQuery here and are the syntax of the insert command is all wrong aswell u give parametes in SQL starting with the @ sign. In summary your all messed up here. First study the basics thorougly then start coding ok, dont worry u'll get over it in quick time. Remember... Every body falls the first time!

Thank you...

I use Visual Studio 2005 with SQL Server Express.
I need to hard code everything and not make use of the data adapter configuration wizard.

I need to do this small project so I can learn how this all works, but was just told: go figure it out yourself...

Can you suggest a walkthrough on MSDN I can follow please. im desperate.

thank you

just copy paste this URL in your MSDN 2005 URL bar

There's whole list of walkthroughs

This one's from that list showing you how to save data

insertCommand.Parameters.Add("telephoneExtension", SqlDbType.NVarChar, 0, "TelephoneExtension");

Why would telephoneExtension have a length of 0? Confused | :confused:

And, you didn't execute the insertCommand you declared so the database will not get updated.

You can use word object library to create new word document and put some text in it so iterate through all the rows of datagridview and put the text in word document.

Locating Zip folders

Hi,
I have to unzip multiple folders present in a single folder using c#. I have the code for doing this and it is working fine. For using this code I have to select the file that is to be unzipped and then after unziping it I have to select the next zip file and unzip it and so on. This is a very long process. Can anyone tell me how to unzip all the zip folders present in the parent folder at one go.
thanx
Nitin.

You can use Directory.GetFiles method for locating all the zip files and then use your code
I think general scheme whould be like this

<br />
<br />
string[]zipFiles;<br />
<br />
foreach(string zf in zipFiles)<br />
.<br />
.<br />
.<br />
<br />
//your code here<br />
<br />

hope the post would help

thanx

Re: Locating Zip folders

you can filter the files with using the overloaded version of the GetFiles(string path,string searchPattern)

it would be somewhat like this for zip files

<code>
string[] files=System.IO.Directory.GetFiles(path, "*.zip");
</code>

good luck

how could i access the user control's objects from its parent control.

i've created a control which includes a listbox and a another usercontrol(CHILD1)..say control CHILD2.

now m dynamically adding CHILD2 control within a control say Parent1. now i wants to access the values entered within the CHILD2..which provides me the values of the listbox and the CHILD1's control.

but the debugger shows that the listbox is no more exist in the class of CHILD2 itself...

is there any way to get the values from all the control ... in the parent control..

thanks in advance

Deserialization question

16-Aug-07 22:39

Hi,
i have a little quiestion, about deserializing a custom type...I want to deserialized this custom type but actually i dont know it. What i mean is for example i have a type called TypeA - i serialized it. But when i want to deserialized i dont know what type i have at the xml file(for xml serialization). I want to find it out.
Is there way to find what type i have?

Re: Deserialization question

J4amieC16-Aug-07 22:56

One option would be to serialize as part of the object the Type's FullName.

this.GetType().FullName

This wont help you on "automatically" deserializing that object, but you could directly interrogate the Xml to determine what the type was of the serialized object.
