I have a requirement.I have a user control in which based on the enum selection I need to add textbox or combobox at design time.For example if enum value = 0 then textbox should be added in usercontrol - if enum = 1 them combobox should be added.The changing of enum value will be done from form1.Means the
blank user control will be droped on the form.From that from I will change the enum value.Based on that
the control should be created.and the controll should hold all its properties.
Can any body help me for this.

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

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

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
