What do you mean by that? You want to change session variable on button click ?
You just need to update the session variable. Better you post the code and ask your query.

I don't think "null" is good name. I would do

Session("ShowImage") = True
Session("ShowImage") = False

Custom Coplex Object get from WebService method

Hi,
I have a serious problem as use web service in .net,

the problem is described in the following link to microsoft http://support.microsoft.com/kb/815131

I have to work with three Web services, each of which I shall return complex objects such

is array containing an array of complex objects

eg

Elem ele = new Elem();

class Elem{

Arrayd[] arr = new Arrayd[x];

...
}

class Arrayd{

dettagliopre[] dett = new dettagliopre[x];

}

class dettagliopre{

string uno;
string due;
string tre;
string quattro;
....
}
...Classes are too long, but if necessary to send the following....

when using web service I get the data the utility of visual studio does not recognize the objects serialized in the proxy class and associates the type of return to type System.Data.DataSet or System.Data.DataSet []

...Furthermore, the data returned from the three web service must be compatible with each other...

I apologize if I was not clear whether or not I have respected the rules of the forum ...

Regards Aldo

what do you think %20 means? why do your want to remove it? What do you think will happen if you remove it? Just think about it.

%20 reperensts the space in "About Us.htm". Now what happens when you remove it, you get "AboutUs.htm". Is that what you want to get. I don't think so. Suspicious | :suss:

you see, sending an email is unpredictable. It takes its own time. Don't rush it with urgent or the system will throw all sorts of exception as a protest. Pretend it is not urgent and it will go zoom. Another thing I find it very useful is bribing the loclhost, chocolate chip cookies are the best bribes.

Try to debug your code. It is telling you, your message is not properly formatted. what else can I say?

Hi all,
I have this client who knows nothing about web in general and now wants to open and edit images in web.
Is it possible that i display an image in a aspx page (some images are really huge > 100 Mb) and let the client edit it (add some text areas like in mspaint) and then save these changes to that image replacing the old one. thinking out loud is it possible to open the image with mspaint in the aspx page then the user submit changes and save over the old path maybe
Any ideas and thanks in advance

You can use third party asp.net image editing [^] controls or look at this one[^]

I don't think so. Imagine if someone can open your local applications from an aspx page.

now i use this master page in login.aspx
is there a way to put html tags in asp:content???
if not then how to put title of the current page??

Confused | :confused:

You can use more then one Content Place Holder. So just place 2nd Place Holder at the top in Login.Master , and in the Login.aspx type the title of the Login Page.

Or in the Master Page at the Page_Load()

you can get the name of the current page

some_variable = System.Web.HttpContext. Current.Request.Url.AbsolutePath

and then type a switch statement to set a Label at the Top.

Like

If (some_variable.Contains("Login.aspx"))
         lblTitle = "Login Page";

How to convert any file to .pdf using Adobe PDF Printer ?

Krushna Sahu25-Mar-09 3:28

Hi,
I've an application developed in ASP.Net to convert any file to pdf file using PDF Printer.
In the .aspx page I've kept one button control and in the click event I've written :

protected void Button1_Click(object sender, EventArgs e)
{
try
{
System.Diagnostics.Process printProcess = new System.Diagnostics.Process();

printProcess.StartInfo.FileName = "E:\\Krushna.doc";

printProcess.StartInfo.Verb = "printto";
printProcess.StartInfo.Arguments = "\"Adobe PDF\"";

printProcess.StartInfo.WindowStyle = ProcessWindowStyle.Minimized;
printProcess.StartInfo.CreateNoWindow = true;
printProcess.Start();

printProcess.Dispose();
}
catch (Exception ex)
{
throw ex;
}
}

I've set the PDF Printer to my default printer.
In the properties of the PDF Printer, in the Port tab, I've set the port to "My Document\*.pdf " . It will save the .pdf file to My Document.

I'm using ASP.Net 2.0 with IIS 5.1 installed.

The issue is :
This is working fine while running the application directly(i.e. the Krushna.doc file is converting to Krushna.pdf and save to My Document Folder) .

But when the application running from IIS, it is asking to save the pdf file i.e. one save dialog window is opened. But I need to directly save the pdf file to the My Document Folder.

Please reply...It is urgent requirment.

Thank you.
