I have 2 images in my sql server dataset. I need to merge and show as a single image in my aspx file.
Any idea how to do that
Thanks in advance

Create a Bitmap object with the size of the combined images, and draw the images onto that. Save the bitmap to Response.OutputStream.
You need to do this in a separate page, so that the browser can request the image after loading the regular page.

Add an image control to your aspx file that points to another aspx file with whatever parameters you need to find the images. In this other file, pull the data out the database, use something in System.Drawing (I can't be more specific than that, sorry!) to merge the images together and then push them down the response stream after setting the content type to whatever image type your serving.
Or an easier way might be to simply put two images on the page styled in such a way as they appear as one (therefor skipping the image mergin bit)

The method I have coded does not work well when the element is wrapped within multiple DIV elements?
function calcXY (obj) {
var x = y = 0;
while (obj != null && obj.nodeType == 1) {
// alert (obj.nodeName + ' ' + obj.offsetTop);
x+= obj.offsetLeft;
y+= obj.offsetTop;
obj = obj.parentNode;
}
alert ('Location of obj is ' + x + ',' + y);
}
Can anybody help me with a suggestion or a better method?

:(I'm having problems with my resource manager in ASP.NET 2.0 after conversion
from ASP.NET 1.1.
Here is a background:
In ASP.NET 1.1
All my user controls and aspx pages inherit from base classes. A base class
includes this property (among others...):
Private m_rscResources As System.Resources.ResourceManager
Public ReadOnly Property rscResource() As System.Resources.ResourceManager
Get
If m_rscResources Is Nothing Then
m_rscResources = New
System.Resources.ResourceManager("MyPortalNamespac e.Strings",
System.Reflection.Assembly.GetExecutingAssembly)
Return m_rscResources
Else
Return m_rscResources
End If
End Get
End Property
In my application root folder I have two files. One strings.resx and one
strings.sv.resx. When I call the rscResource.GetString method I simply use
the tag name to get the translation.
Label1.Text = rscResource.GetString("First name")
In 1.1 this works absolutely fine. However, In 2.0 (after conversion), it's
not working. The error message I get from .NET is:
System.Resources.MissingManifestResourceException was unhandled by user code
Message="Could not find any resources appropriate for the specified
culture or the neutral culture. Make sure
"MyPortalNamespace.Strings.resources" was correctly embedded or linked into
assembly "App_Code.lkep0udn" at compile time, or that all the satellite
assemblies required are loadable and fully signed."
I've tried to dynamically get the current executing assembly name like this:
m_rscResources = New
System.Resources.ResourceManager(System.Reflection .Assembly.GetExecutingAssembly.GetName.Name
& ".Strings", System.Reflection.Assembly.GetExecutingAssembly)
Same error message (but 'MyPortalNamespace' is replaced).
I've tried a number of things to work around this, but I still get this
error message. I've tried placing the resource files into different
directories including App_Code, App_GlobalResources, application root etc.
None is making it better.
So, here I stand...
I want to clarify that I know how you can use resources in 2.0, but that's
from scratch. I have hundreds and hundreds of places where I use
rscResource.GetString("MyKey") and I really don't feel I want to change all
that now. p
please suggest me how to make it possible

Is there a way in javascript to call a function that is in an external DLL? Without ASP.NET? I would like to pass back events to a C# DLL program that I’m running.

That may be out of the question. You may be able to achieve it with Flash.
Nonetheless, try this page. It may help...

Thanks for the quick response. I think since I’m using WebBrowser control in my C# dll I can use the ObjectForScripting method to pass what I need from the javascript.
Thanks again

New to devlopment with VS.net, I created a very basic page that should query a database and return some data. It works fine on the development station but when I run it on the server it does not appear to work. The screen appears to refresh but nothing else happens. In my feeble attempt to degug I added a simple button and added the following code:
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
lblNotes.Text = "Test"<br />
End Sub
This also appears to work on the workstation, but not on the server.
How can I chase this down? I know this may be a simple question but I am self teaching myself and little things like this appear to be my biggest challenge....

Did you compile in debug mode? Only then PDB files are created.
|
|
|
|
|
How did you deploy the solution to the server?
|
|
|
|
|
Thanks for the response, the solution is set to build in debug mode, deploying to the server is esssentially a copy of the project on the server, not sure if that is teh right way or not.

Dim ds as DataSet = SqlHelper.ExecuteDataSet(..........)
Dim str as String = CType(ds.Table(0).Rows(0)(1),String)
Note: ds.Table(0).Rows(0)(1) is the column (bit) of your table.

The answer that I posted previously is for converting the bit field of datacolumn to string..
I have no idea about "How to get the ceckbox value in to an Excel File"

Hi there,
I want to pass an array as an hidden field of html that is created in php. i.e.
$moduleList[0] = "abc";
$moduleList[1] = "xyz";
$htmlString = "<input type='hidden' id = 'moduleListForComboProjectList' name='moduleListForHiddenComboProjectList' value=$moduleList>";
Now, I am sending this to HTML and in html I got following:
<input type='hidden' id = 'moduleListForComboProjectList' name='moduleListForHiddenComboProjectList' value=Array>
And now I am fetching value of that hidden field from javascript
moduleArray = document.getElementById("moduleListForComboProjectList").value;
alert ("array = " + moduleArray);
then I got "array = Array" but as I want fetch data by loop then it is not giving me proper result. It is taking Array as a string.
can you please tell me how can I get the passed values from php????

You cannot print an array to HTML. You could just turn it into a CSV format (by using the "foreach" function but that is it.
