What exactly do you want it to do ? You can't expect to read barcodes across ASP.NET, although you can generate and display them, the ASP.NET part is then irrelevant, you just add the images to your page.

You may probably add the custom control to Web Control Library. and generate the assembly. Then, reference this assembly from the application that you wanna use this control.

Hello All,
What is the best practice for storing images for web application?
Let's say I wanna develop the web photo gallery application like Flickr. Where should I store the images that uploaded by user? Database or File?
I think storing the images in the database would be good for security reason but there is more cost for rendering the image.
If we store the image directly to file system, we have to give the "write permission" to the user so it might cause the security problem..
So, I'm not very sure where those image should be saved. It would be great if you all can suggest me..
Thanks in advance..
Thanks and Regards,

Store paths in the DB, then you can just pass paths around to img tags to show the images in your app.
You don't have to give any sort of write permission, you get the images passed into your web app, and your app writes them to the location, the user has no such permission on the folder.

Thanks for your reply. Chrisian.

I think I need to repharse my sentense.
Let's say the application that I'm working on is Photo Gallery. So, there will be one feature that allows the users upload their images. My question is that where I should store those uploaded images. Should I store the image as binary in database or store the path in database and store the images in upload folder?
If I store the path ( "./upload/user1/album/image1.jpg") in database, the image ("image1.jpg") has to be uploaded under "/upload/user1/album/" folder. So, I will need to give "write permission" to "upload" folder or "/upload/user1/" folder.
Is it good way to do?

I’m encountering a new kind of problem using Crystal Report for .Net 2005.
If I export a report in a Word or Excel format it works fine but when I set the content type to PDF I get the Adobe PDF splash screen and nothing happens, the content of the web page doesn’t change.
This is a summary of the code I’m currently using (that used to work with CR 8.5):
Dim crExportOptions As ExportOptions
crExportOptions = ExportFileFormats.PDF
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/pdf"
crExportOptions.FormatOptions = New PdfRtfWordFormatOptions
crExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat
Dim req As ExportRequestContext = New ExportRequestContext
req.ExportInfo = crExportOptions
Dim st As System.IO.Stream
st = ReportDocument.FormatEngine.ExportToStream(req) -- (ReportDocument is a crystal reports filled with all the required parms and data. Works with Word and Excel)
Dim b(st.Length) As Byte
st.Read(b, 0, st.Length)
Response.BinaryWrite(b)
Response.End()

Hello friends and gud morning..
I am newer to asp.net and i want to implement ajax technology in my applications. So Please give me links to understand simple ajax implementations and there use in web applications

Depends what you mean by 'simple. You've been given a link to the Microsoft AJAX library, that will give you some AJAX functionality without writing any AJAX code. Writing your own simple AJAX code would not involve using this library at all.

Is the Repeater control able to handle input? This is the code I am using right now. I am not able to get the values from the TextBox fields.
I am trying to populate a series of TextBoxes that will contain user input for the related process field. I am using ASP.NET 2.0 and C#.
Thanks!
Client Side:
<asp:Repeater ID="rptrProccessInput" runat="server">
<ItemTemplate>
Process: <%# DataBinder.Eval(Container.DataItem, "process") %> Target:<asp:TextBox runat="server" ID="txtTarget"></asp:TextBox> Comment:<asp:TextBox runat="server" ID="txtComment"></asp:TextBox><br>
</ItemTemplate>
</asp:Repeater>
Server Side:
protected void Button2_Click(object sender, EventArgs e)
{
TextBox txtTarget = null;
TextBox txtComment = null;
foreach (RepeaterItem ctrl in rptrProccessInput.Items)
{
txtTarget = (TextBox)ctrl.FindControl("txtTarget");
txtComment = (TextBox)ctrl.FindControl("txtComment");
Debug.WriteLine(txtTarget.Text +":"+ txtComment.Text);
}
}
|
|
|
|

You are not passing values to Textbox
try this
<asp:TextBox runat="server" ID="txtTarget" Text='<%# DataBinder.Eval(Container.DataItem, "process") %>'></asp:TextBox>

In this code if a lot is occupied the label turns red and if not its green.
But instead of using color i would like to use images to represent this change.
Can any one Help??
<br />
Dim sqlDataReader As Data.SqlClient.SqlDataReader= sqlLotStatus.EndExecuteReader() <br />
<br />
Dim lotStatus As String<br />
Dim textLabelName As String<br />
Dim colourLabelName As String<br />
Dim textLabelCtrl As Label<br />
Dim colourLabelCtrl As Label<br />
<br />
While sqlDataReader.Read()<br />
' Derive label names.<br />
textLabelName = "Label" & sqlDataReader("Lot_id").ToString() & "Text"<br />
colourLabelName = "Label" & sqlDataReader("Lot_id").ToString() &"Colour"<br />
<br />
' Get Label controls with derived names.<br />
textLabelCtrl = CType(Me.FindControl(textLabelName), Label)<br />
colourLabelCtrl = CType(Me.FindControl(colourLabelName), Label)<br />
<br />
' Set control properties for lot.<br />
lotStatus = sqlDataReader("status").ToString()<br />
If lotStatus = "occupied" Then<br />
textLabelCtrl.Text = sqlDataReader("Lot_id").ToString() & " is not available"<br />
colourLabelCtrl.BackColor = Drawing.Color.Red<br />
Else<br />
textLabelCtrl.Text = sqlDataReader("Lot_id").ToString() & " is available"<br />
colourLabelCtrl.BackColor = Drawing.Color.Green<br />
End If<br />
End While<br />

OR.
You can set the style to that label.
Example :
Style ~
<style type="text/css">
.TurnOn{
background : transparent url(http:
}
</style>
Code ~
If lotStatus = "occupied" Then
Label2.CssClass = "TurnOn";
Else
Label2.CssClass = "TurnOff";
End If
Hope it helps..

This has been really bugging me, what's the best way to tell the ContentPlaceHolder not to render a <span> tag? It seems quite a design flaw because if you include a block element such as <p>, <table> or <div> inside the content page then it will not be XHTML 1.1 Strict compliant  . Anyway of changing the rendering to render nothing, or a <div> tag, short of writing my own ContentPlaceHolder of course.

You mean, p,table,div tag can't be put inside the ContentPanel?
It is very strange to me. I used to us those tags in ContentPanel all the time. I didn't have any problem with it...

hi,
i want to build a winform that hosts an internet explorer browser window.
for the aspnet page that the browser navigates to, i want to detect if the browser is hosted in winform or not.
i thought to navigate the hosted ie to an address with a parameter like addres.com?ishosted=true
but the user can check whats the address and copy it to a regular browser window without the hosting winform and i dont want to allow this.
can anyone think of a better solution ?
thanx

I don't know if there's any way you can tell, unless you can check the state of the window itself, if it's a child window. I very much doubt you can do that with javascript.

ok, another question.
correct me if im wrong, but to my understanding, i can host any application that has an activex component (like word, excel, acrobat etc) inside a winform application.
how can i (if at all) create a general winform that can host every application type, even those that doesnt arrive with an activex component ?
thanx again,
|
|
|
|
|
Yes, in theory.
You can't, at least not in a way that is reliable and OK for production code. You can try embedding any window as a child in your app, but anything could happen. If we didn't need ActiveX controls to do this, no-one would bother writing them.

Hi, I am trying to get user to input text in a form (textboxes) in all CAPS irrespective of CAPS lock turned on or off. I would really appreciate if someone can suggest how this can be done.
Thanks!

You could force them to with some fancy Javascript, but why bother? (And anyway, they may turn Javascript off.) But there's nothing to stop you converting their input to uppercase when they post it back to the server if you want, with a simple ToUpper method....
