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
Chandrakanth

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

I already did that.
Read my previous post, and if there is anything that you don't understand, say what it is.

Hi jagadeeshkumar2106,
suppose u have a one textbox names text1 ok now try this code
// Code is here.
try
{
DateTime d = new DateTime();
d = Convert.ToDateTime(Text1.Text.Trim());
// If it will not be in proper format then it will throw an error ok
// if u know error type about converting then u can also write one another catch block regarding that.
}
catch(Exception ex)
{
Response.Write("Enter Date is not in valid format");
}
I hope it will work.

Hi Clever People.
I have create an application that exports data to Excel. It first writes the data to a FileStream where it will ask you if you want to open or save the Excel file. Now the problem is that it works very well on our one server. Unfortunately we decided to move all applications accross to a different server.
They both are identical where setup is concerned, but for some or other reason I am getting the Following Error when trying to Export to Excel.
InvalidOperationException was unhandled by user code.
Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
Can anyone tell me what we might have missed please?
Kind regards,
Elizma

I have not experienced this yet. But Google[^] returned many many results

Hi There,
Thanx for your reply. I also googled it before I came to post my question here. Unfortunatley nowhere in the over 600 results does it actually state what is causing it. They also cover the MsgBox problems. I am not making use of it. I am using the normal Filestream objects. Like I said. It works on our one server, but not on the new server. I am trying to figure out what we missed with the new server.
Kind Regards,
Elizma

Hi,
1. Tell me, when you created your report, did you use the dataset that you created, or did you connected directly to the database?
2. When creating the Dataset, dropping the tables from the database on the dataset, have you deleted the fill objects at the bottom of the table?
3. Have you created an instance of your dataset and fill the tables in the dataset with the code from the database?
4. Lastly you have to set the datasource for this report to the dataset instance that you created and filled.
Let me know if you need assistance. I struggled myself with this in the beginning.
Kind Regards,
Elizma

The data layer is a class or dll that contains all your DB access code.

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

What problem are you facing?
|
|
|
|
|
I have no idea about how to do it
Thank you
|

What I like to suggest you is that you should learn about ASP.NET before start working on the project.. Basically, we all here are not for teaching the tutorials. What we do here is that we give the advice if someone needed it and we help other people to solve their problem when they ask the specific question..
If you want to learn about ASP.NET 1.1, you can start reading the QuickStart tutorials from Microsoft website.. or you can buy the book too..
|
|
|
|
|
Thank you very much for your suggestion but, i am not expecting a tutorial from you. I am just expecting an idea on how to go for it.
|
|
|
|
|
Here is the idea.
1. Suppose: You have two tables called Restaurant (e.g ResID, ResName) and the available foods (e.g. ResID, FoodID, FoodName)
2. Join those both table
3. Get the count of available food, create the temp table or table variable, fill the data (if you have the static count for food name then this step is not necessary).
4. return those data to DataSet
5. Bind this dataset with Gridview.
That's all.
|
|
|
|
|
My database looks like this
SNo Restaurent Items
1 Rest1 Item1
2 Rest1 Item2
3 Rest1 Item4
4 Rest2 Item1
5 Rest2 Item3
6 Rest2 Item4
7 Rest3 Item2
8 Rest3 Item3
And in the Report, Y Axis should be Restaurent values and X-axis should be Item values. And wherever there is a matching point, a tick mark should come.
Thank you
