I have a login form. when i login with my user name it should be redirected to another form. in that form i have a table column with days monday to sunday in which i have 6 text boxes under each day namely intime, outtime, extratime,nonworktime,leavehrs and total. In that if i enter the values for each textboxes ie.., in hours(user enters it daily-day by day) , all the values should be submitted in the database for the corresponding days and should not be able to modify the values which are entered once.

I am trying to add controls to the toolbox for an Ajax site I am building (VS2005 & C#).
I have a sample web.config and it suggests that I need a section called:
sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
However, I already have a similar section called:
sectionGroup name="microsoft.web" type="Microsoft.Web.Configuration.MicrosoftWebSectionGroup, Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Which one should I be using ?
Thanks.

You should use the first one as the name Microsoft.Web.Extensions is changed in the RTM, more details can be found here[^]

I need to create an web page interface for a database
in ASP.NET with C# and I have some problems :
1. First of all how can I connect to the database and how
can I make queries. Sould I use the "DataSource" control or
is it better to connect with code only ?
(The database is on my PC)
2. As I can see there are two types of buttons. The first
is the standard that leads to write code in the *.aspx.cs
file. The second is the HTML button that leads to write code
in the *.aspx file. The first button however is invisible in
my browser. Why is that ?
If you could tell me how to connect to my database in an MFC
project instead of ASP and how to make queries it would be nice too.
I was really disapointed that noone in this site hasn't posted an article
on this matter (Am I wrong?). Anyway, this is the best programming site
there is.
Any kind of help would be much appreciated.

Hi,
It is not possible to write about details of Database connectivity in .NET in this reply. I am giving you a few hints. Using a good book and googling will show you the way.
Important namespaces for connectivity and data related activity.
System.Data.SqlClient - for Sql Server
System.Data.OracleClient - for Oracle
System.Data.Odbc - for other database.
System.Data
Please read about these namespaces.
Read about SqlConnection, SqlCommand and SqlDataAdapter in System.Data.SqlClient.
Similar classes also exist for other namespaces.
Apart from it you need to know about DataSet, SqlDataReader etc.

Small question, big answer - people have written entire books answering that question. Get a book on ADO.NET. Personally, I use SqlConnection and SqlCommand and the Enterprise Libraries.

I don't know. You need to post some code. The "standard" buttons work for me. Have you set any properties that would make it invisible?

Off topic - ask this in the C++ forum.

Umm.. Did you try searching for any? I typed in "connect database MFC" into the search facility here and I got back 36 possible articles that you might find useful.

I need to display images that are contained within our corporate firewall on a clients' web site (which is hosted on a server outside of our company.
Currently, the only way I've been able to grant them access to these images is to impersonate a specific user in the web.config file:
<identity impersonate="true" username="DOMAIN\username" password="password">
This provides a security problem however because if anyone were to ever somehow get a hold of this web.config file, they could use this info to hack into the server. So I'm looking for an alternative method.
Anyone know any other approaches I could take to display these internal images?
Thanks.

i have an ASP.net textbox on my form and a dropdownlist too on my form. How can i set the text to "hiii" using JavaScript? IS this correct
document.Form1.txtTextBox.value="hiii";
I would also like to set the dropdownlist selected index to 0.
How do I do this? As simple as it may sound just bear withe me guys. i really dont know a !@#$ about JavaScript and this is really urgent. I've learnt my lesson though. Tomorrow i'm going to go my self a really good book to teach me this stuff. In the meantime, it'd be great if you could just help me.

You'd need to use document.getElementById(myControlId).value='some text'
The thing to watch out for though is that the control name you defined will probably be prefixed with _ctl0_ or something similar. You can use the object.ClientId attribute on the server side to find out what it should be.

Hi all
I have a datagrid, which holds item name, item price, and its image(all from SQL Server database), what I need is when the user clicks on the image, I need the (id) for the item to be carried to the new page where I want to show more details about the item (expiry date, ...)

Hi all,
I am using a datagrid to display some data.The problem is i want to display my own column name rather than those in database.I am using data adapter and dataset to fill data.
Also how can i show only date in the data grid when the contents in the database is date time.It shows date as well as 12AM in addition which i haven`t inserted.
|

use this
<br />
<asp:TemplateColumn HeaderText="Date"><br />
<ItemTemplate"><br />
<# FormatDate(DataBinder.Eval(Container.DataItem, "DBDate")) %"><br />
<ItemTemplate"><br />
</asp:TemplateColumn"><br />
Use a TemplateColumn as shown above where DBDate is your database data field. FormatDate is your own function to format date. The function can be like this shown below.
<br />
public static string FormatDate(object oInput)<br />
{<br />
if(oInput != null)<br />
{<br />
if(oInput != DBNull.Value)<br />
return ((DateTime)oInput).ToString("MM-dd-yy");<br />
else<br />
return string.Empty;<br />
}<br />
else<br />
return string.Empty;<br />
}
Hope this will help

Define a <columns> collection in the grid, then add column definitions, including the HeaderText attribute

I'm using CompareValidator to validate a TextBox control in FormView. I want to compare with a Label. I find however that when I select ControlToCompare, the Label isn't listed. The only controls to choose from are TextBoxes. And yes the Label does exist and is visible! Any ideas?
Many Thanks
Maj

That's because the Label control is not marked with the ValidationProperty[^]. So you either a) customize the label control or b) use a invisible textbox to contain the value beside the Label so that you can validate the textbox.

hello,
I've build myself a usercontrol with a couple of buttons to which I added event handlers. The control is loaded dynamically using LoadControl() of the Page object. Loading works fine, but the buttons click event in the usercontrol won't fire eventhough the page is posted back. Does anyone know this problem?
thanks a ton, matthias

is it possible you don't register your event after postback?

Follow these steps to add events to your user control.
a) Declare the event within the user control’s code module
public event EventHandler Click;
b) Create a method to raise the event
protected virtual void OnClick(EventArgs e)
{
if (Click != null)
{
Click(this, e);
}
}
c) Raise the event from within the user control’s code.
private void Button1_Click(object sender, System.EventArgs e)
{
// You can add your code here
// Then call the OnClick method.
OnClick(e);
}
As obvious now, you have to handle this Click event (declared above) on the Host or Parent web form.
Happy Coding

Someone to help me please.
I want a checkbox as part of my gridview and also use the checkbox to select the rows that are checked.
How do know the rowindex of the checked row and iterate thru the checked rows?
t.aransiola

Depending on the size of the GridView you could try:
foreach(row in gridview)
checkbox = row.findcontrol(check box id);
if(checkbox.checked)
this row is checked
endforeach
Obviously the above will need some interpretation (and off the top of my head I'm not sure whether its the row or the cell that is the INamingContainer?)

I have an application which communicates with WebServcie.I installed the application and the WS on a srever of test,i've got all the results i'm waiting for.But when I installed the Web site and the WS on the WEBFARM, the Web site did no longer communicate with the WS. The site can communicate with the WS installed on the server of test.And another site installed on a site different from the WEBFARM can communicate with the WS installed on the WEBFARM.
The problem is that the Web site installed in WEBFARM cannot communicates with the WS installed on the same WEBFARM. What to do!
