Hi,
There is a requirement to be able to upload files using a website (asp.net 2.0) . There should be a kind of validation on these files before the upload is allowed. What I am not sure of is how can I do any kind of validation on the files before the upload? For example if a file of type excel or .txt is to be uploaded, the website has to first check to see if there are certain data in the file... then if all ok the upload is allowed.
Thanks

You will have to uploda the file to the server first and do the checking there. If the checking fails simply delete the file.

Well... you can use Javascript to at least check the file extension - this doesn't guarantee the file is valid, of course, but it will help eliminate some innocent errors....
If you have a file input box on your form
<input id="file1" type="file" onchange="checkFile(this)" name="file1">
You can use the following function - change the line
var fileTypes=["gif","jpg","jpeg"];
to suit whatever file extensions you want to check for.
function checkFile(what){
var source=what.value;
var ext=source.substring(source.lastIndexOf(".")+1,source.length).toLowerCase();
// valid file types
var fileTypes=["gif","jpg","jpeg"];
for (var i=0; i<fileTypes.length; i++) if (fileTypes[i]==ext) break;
if (i==fileTypes.length) {
alert("THAT IS NOT A VALID FILE\nYou can only uload files with the following extensions:\n\n"+fileTypes.join(", "));
}
}
// -->
</script>
This script was adapted from one I downloaded from
The JavaScript Source!! http://javascript.internet.com

They would probably appreciate your adding such comments to this script if you use it on a web-page.

Hi there,
Do you mean that you have to read the file's content to validate at client-side before uploading? if so, you upload file to server and validate at server-side. You dont have permission to read file at client

For Print
1. window.print()
THis will print whole page
2. Give Link Print on click of which it will open IE popup using window.open()
which only contains grid control having same result and in that popup give print button on click of which it will print whatever there in the popup means as per our logic only grid with result.
You can hide print button using document.form.btnPrint.style.visiblity = hidden
OR
objBtn = document.getElementById(btnPrint)
objBtn.style.display = 'none'

Me.lblShowGrid.Controls.Add(DataGrid1)
Page.Controls.Add(DataGrid1)
Because you add the grid control to the Page, so the grid and its child controls inluding the textbox will be placed outside the form element, and you will get the error. Instead, you should get reference to the form element, and add the grid to the Controls collection of the form. Another option is to place a container like Panel or PlaceHolder control in the form, and add the grid to this container.

I used Google Web Service to do web search, and I have already succeed to use Google Web API to do that in the same web page. But my problem is that how does the search result returned and open a new web page to show these records.
Please give me some guide. I will appreciate your teaching. Thank you.

There are two options come to mind:
+ You open the new page and pass the search parameter to this page, the new page is responsible for calling the search APIs and displaying the result.
+ You use the current page to call the search APIs, then persist the result somewhere for example in the Session, and open the new page. The new page should be able to access the persisted result so that it can display on the web page.
Just some ideas.

Hi..
I have visual studio 2003 and I am trying to use Google Search Web Service(C#).But I got the error:
DataBinder.Eval: 'EProjects.googleapi.ResultElement' does not contain a property with the name title.
The source code of the Web Form that should display the Google Search Results:
using googleapi;
/// <summary>
/// Summary description for GoogleResults.
/// </summary>
public class GoogleResults : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.ImageButton imgPrev;
protected System.Web.UI.WebControls.ImageButton imgNext;
protected System.Web.UI.WebControls.DataList lGoogle;
public EProjects.googleapi.GoogleSearchResult gsR;
public EProjects.googleapi.GoogleSearchService gcs;
private void Page_Load(object sender, System.EventArgs e)
{
gcs=new googleapi.GoogleSearchService();
gsR=gcs.doGoogleSearch(licenceKeyString,Request.QueryString["Query"],
0, 1,true, "", true, "", "", "");
PopulatelGoogle(gsR);
}
#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeComponent();
base.OnInit(e);
}
/// <summary>
///Required method for Designer support - do not modify
///the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
private void PopulatelGoogle(GoogleSearchResult gsR)
{
lGoogle.DataSource=gsR.resultElements;
lGoogle.DataBind();
}
}
}
The HTML code of the same page:
<table height="100%" width="100%">
<tr>
<td colSpan="2">
<asp:datalist id="lGoogle" runat="server">
<ItemTemplate>
<span style="font-size:17px;font-weight:bold;">
<%#DataBinder.Eval(Container.DataItem,"title")%>
</span></br>
<%#DataBinder.Eval(Container.DataItem,"snipper")%>
</br> <a href='<%#DataBinder.Eval(Container.DataItem,"URL")%>'>
<%#DataBinder.Eval(Container.DataItem,"URL")%>
</a>
</ItemTemplate>
<SeparatorTemplate>
</p>
</SeparatorTemplate>
</asp:datalist></td>
</tr>
<tr>
<td align="left"><asp:imagebutton id="imgPrev" Runat="server"></asp:imagebutton></td>
<td align="right"><asp:imagebutton id="imgNext" Runat="server"></asp:imagebutton></td>
</tr>
</table>
I tried to solve this problem for a long time but I couldnt please help.

hi
can anybody tell the difference between configSource and file attributes in web.config file
coolsweety
|
|
|
|
|
+ The file attribute specifies an external file containing custom settings like you do in the appSettings entry of the web.config file. Meanwhile, the external file specified in the configSource attribute contains the settings for the section which you declare the configSource for. For example, if you use the configSource attribute of the pages section, then the external file will contain the settings for the pages section.
+ The custom settings declared in the external config specifified in the file attribute will be merged with the settings in the appSettings section in the web.config file. In the meanwhile, the configSource does not support merging, it means that you'll have to move the entire section settings into the external file.
