It doesn't matter if there's no records, the binding won't fail. You can always check post binding (i.e. count the items in the list) if you need to do something in that case. Calling dr.Read moves the reader onto the second record...

Do Like this
Member 3402886 wrote: ddlModelTypes.DataSource = objRdr;
ddlModelTypes.DataValueField = "TypeId";
ddlModelTypes.DataTextField = "ModelType";
ddlModelTypes.DataBind();
No need to Call
Member 3402886 wrote: if (objRdr.Read())
No need to Call , otherwise everything else looks ok , it should work

Hello friends,
I am using a FileUpload Control inside Customized CreateUserwizard Control. I am accessing textboxes inside the CreateUserWizard as ((TextBox)BusinessDetWizardStep.FindControl("txtfirmsname")).Text.Trim().
I also put a fileupload inside this wizard. But while catching the file in code using this code
if(((FileUpload)BusinessDetWizardStep.FindControl("fileupload1")).HasFile)
{
}
The Fileupload control does not get any file to upload...Why this is happening? What could be the cause and solution for this?
Thanks...
|

|
|

Are you using the fileupload within an updatepanel by any chance?
|
|
|
|
|
Thanks for the reply..
I am not using fileupload within UpdatePanel. The FileUpload is contained within WizardStep directly..

You don't have any quotation mark at the beginning of the string.

Isn't it always - but only to you, nobody else cares.
In the time it took you to post the question you could have tried it for yourself, so why don't you just go into debug and try it?

Is there any way to generate secure or cryptographic random numbers without using any third party code/tool(watever...English is not my first language). If not, then is CryptoAPI recommended?
I am using ASP/IIS 5.0.

Hi. I have a desktop application that I want to load on the internet or just its database. I really have a vague understanding on how web service works other than your application being loaded on the web. My goal is to retrieve data from the internet instead of a direct connection in a wifi connection. I was asked to load the data on the internet before being retrieve by the user. Can someone tell me how I can migrate my desktop application to the web? What I would need? What I have to do? Do I have to recreate my application again if I'm going to place it on the web (It would be a hassle)?
In simple terms, the client (PDA phone) retrieves data from the internet, then sends information to the server (desktop app) but must go through the internet. So basically. Instead of a direct wireless connection from wifi, we are required to add the internet as a bridge of communication between the two.
P.S.
- By the way, it doesn't necessarily have to be used by a certain webhost. Using localhost would be just fine with me, as long as it can connect via wifi. I really really need your help for this. Thanks!

The easiest way to do this would be to build an ASP.Net page for the client. I'm assuming the PDA Phone can view webpages, so you'll have to have a phone to test your pages in the phones the browser. Both the web client and Desktop client should get the data from web services. This is actually very easy to set up.
You can create one webservice method to do all the work for you. Simply create one service with SQLProcName and SQLParameter array for input and DataTable as result. Should be easy.
The trickiest part of web services is securing them. Personally, I don't bother with certificates, just pass a userName and passWord as parameters in your webservice method. If the wrong info is passed, simply don't execute any code.
Good luck.
I didn't get any requirements for the signature

I see. I'm sorry but I'm very new to ASP.NET, and I can't seem to understand what you meant by a service with SQLProcName and SQLParameter. I have scanned a few tutorials and few ebooks but nothing seems to lighten me up. And also, I tried to create a webservice, added a windows form, and I tried to test run it but I get an error message like this:
"Windows start service failure:
----------------------------
Cannot start service from the command line or debugger.A windows service must first be installed
(using installutil.exe) and then started with the server explorer, Windows services Administrative
tool or the NET START command. "
--------------------------------

i want to display my images in datalist.
i save my images path in access database(like this Product\hotel\product1.gif)
my images are in a speial folder which under the App_Data.
how can i connect datalist-images directory-image? i connected to database with accessdatasource1.

U need to use an Image Control in DataList(Edit Template)
and set the Image Control URL in ItemDataBound event of DataList
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
Image I1 = (Image)(e.Item.FindControl("Imagex"));
I1.ImageUrl = dth.Rows[e.Item.ItemIndex]["ImageURL"].ToString();
}
"dth" is the DataTable which I am using as DataSource for DataList
The URL should be "App_Data/product1.gif",to retrieve the image .
As in ur case if URL is stored as eg:Product\hotel\product1.gif
Then you need to convert it to "App_Data/product1.gif",
using string manipulation .

I can only see fractions of your code. Use the "Ignore HTML" option when you are posting markup code.

Is it the mail message that is not displayed, or the contents of the message that is not displayed? Where is it not displayed?

How are you embedding the image? What do you mean by "late to send"?

Above is the way i used to send a mail with embed image and this becomes slow to send mail i.e to send 5 mails for example it takes 3 minutes.
II
i tried to write an image inside td of Body message src=mypath instead of
src='cid:imageId' but result is i am getting mails deliverd but if i open a mail then mail not displayed any images

specify full path of your image like
http://yoursite.com/images/S.JPG....

Hello to everybody,
I'm currently developing a 2 level menu using jQuery... I load data from a Webservice and populate the toplevel item and sublevelitems... my webapplication is made of ascx and I've got a main page that load the ascx, I was wondering if there's a way using jQuery to notify the server that a menu item has been clicked ( I tried creating an ajax asp.net server control menu but got lost, so I moved to jQuery)...
Thanks in advance

Hello,
I am planning to embed an ASPX file in my web application as an embedded resource. Now, when I call the file as an web resource url, I get the file downloaded as a text file instead of being executed. So, I think, if there is a correct mime type I can set for this aspx file, I can let the IIS know to execute it. Can you give me any idea?
I tried Virtual File System instead of web resource, and it works fine but only problem is, Virtual file cant be run on medium trust level hosting. So, your help is highly appreciated.
Regards,
Emran
