Hi...

Is it posible to delete a file (from a hard disk) after adding it into the database by clicking on a button. (the click event allready stores the file in the database) I want to delete the file (from the hard drive) using asp.net. BUT is it possible to do this using asp.net code???

I am very new to asp.net but have worked with c# before. (and a little vb.net --- but not much)

2nd question... als in ASP.net
How do i gain focus on a control? (lets say "myTextBox")
i thought it should work like this... myTextBox.Focus(); but this is not working... Why not? It seems to work in the form load but not on the button click event???

Hi,
you can delete file if you are having permission to delete it.

Create fileinfo object of that file and then delete it.

And to set focus you can do below code.

private void Set_Focus(string controlname)<br />
{<br />
string strScript;<br />
strScript = "<script language=javascript> document.all('" + controlname + "').focus() </script>";<br />
RegisterStartupScript("focus", strScript);<br />
}<br />

Thanks,

Hi,
you can do Reponse.Redirect("full Path of file")
So it will open file in browser.

But the browser will only open those file types that it can support within itself. If you try to, for example, open a .cs file, it will open outside the browser.

Do you want this to happen immediately, or for the page to post back ? If the former, you need to write javascript to run when the button is clicked, to find the textbox control and put text in it.

Dropdownlist selected index changed event not firing

JacquesDP13-Dec-07 23:28

Hi all,

I sit with an issue and have absolutely no idea why it is happening.

I have a DropDownList, as follow:

<asp:dropdownlist id="ddlPaymentMethod" runat="server" onselectedindexchanged="ddlPaymentMethod_SelectedIndexChanged">
</asp:dropdownlist>

Then in the code-behind I have the following:

protected void ddlPaymentMethod_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlPaymentMethod.SelectedIndex.ToString() != "")
{
SetDivVisibility(ddlPaymentMethod.SelectedItem.Value.Trim());
}
}

But for some reason, when I run the program, and change the value within the DropDownList, it never enters the SelectedIndexChanged event.....

Any ideas or solutions would be greatly appreciated

Thanks in advance

Hi,

I want to develop a comparison chart. For example,
You want to start a new restaurant in a particular place. So, what you do is you will list all the items that are being supplied by the restaurents already available on X-axis and all the restaurents on Y-axis.
Now you put a tick mark against each item taking one restaurent at a time.

item1 item2 item3 item4
Rest1 . .
Rest2 . . .
Rest3 . .

My report should look something like this and i am working in asp.net 1.1
Thank You in advance
Thank you

Unable to cast object of type 'System.Byte[]'to 'System.IConvertible'. in Uploadiong Image in to Sqlserver

Hi,

This is from Chandrakanth.

Now i am uploading Image in to Sqlserver2005.

I have written coding like this using Enterprise Library

protected void btnUpload_Click(object sender, EventArgs e)
{
if (upXLTalisma.PostedFile != null)
{
if (upXLTalisma.PostedFile.ContentLength > 0)
{
HttpPostedFile objHttpPostedFile = upXLTalisma.PostedFile;

if (CheckValidFileType(objHttpPostedFile.FileName))
{
int intContentlength = objHttpPostedFile.ContentLength;

byte[] bytImage = new byte[intContentlength];

objHttpPostedFile.InputStream.Read(bytImage, 0, intContentlength);

KF.Search.StoreImage(Convert.ToByte(bytImage));
}
}
}
}

public static bool CheckValidFileType(string strImage)
{
string strImageFile;
strImageFile = strImage;
if (strImageFile.LastIndexOf(".") == -1)
return (false);
int i = strImageFile.LastIndexOf(".");
strImageFile = strImageFile.Substring(strImageFile.LastIndexOf(".") + 1);
return (strImageFile.ToUpper() == "JPG");
}

This is the code i am using in Class file

public static void StoreImage(byte strImage)
{
try
{
Database objDataBase = DatabaseFactory.CreateDatabase();
DbCommand objDbCommand = objDataBase.GetStoredProcCommand("STP_KF_IMages");
objDataBase.AddInParameter(objDbCommand, "@Image", DbType.Binary, strImage);

objDataBase.ExecuteNonQuery(objDbCommand);
}
catch (Exception Ex)
{
throw new Exception(Ex.Message.ToString());
}
}

but i am getting error in this line,

KF.Search.StoreImage(Convert.ToByte(bytImage));

and Saying

"Unable to cast object of type 'System.Byte[]'to 'System.IConvertible'. "

Can any one suggest me what to do for that coding.

Thanks And Regards

Oops! The Read method returns the number of bytes actually read, which can be smaller than the number of bytes requested. If you ignore the return value of the method, you don't know how much of the data that you actually get.

You have to get the return value from the method to see how much data was read, and loop until you have read all of the data (you reach content length, or the method returns zero).

mrgaddam wrote:

You can't convert a byte array into a single byte.

mrgaddam wrote:
public static void StoreImage(byte strImage)

This method takes a single byte as parameter. That is truly pointless as you can't store an image in a single byte. Change the method to take an array of bytes.

Using hungarian notaion to specify data type is rather pointless in a strongly typed language. And if you specify the wrong type, as you have here when you gave a byte variable a name that says that it's a string, it's only confusing.

Experience is the sum of all the mistakes you have done.
