Professional just means they get paid to do it. It does not mean they are any good. I've met many "professionals" that I would be surprised if they managed to find the "On" switch.

It gets created where ever you tell it to create it. If you don't there will be a default location depending on how it has been installed.

You should neither know nor should care where the database is physically stored as it can be stored in many different ways. You can store it in a file on the Hard Disk. You can split the database in to many files. You can store the database across disks. You can hand over entire hard disks to SQL Server and let SQL Server manage the entire disk (no file, just a disk).
You connect to a database, not a file (Except for SQL Server Express edition, which can treat a database as a file)

Hi all I am trying to sort a group in crystal report dynamically, the code I am using clears the grouping of the report here is the code I am using
{
SortFields targetSortField = Rpt.DataDefinition.SortFields;
DatabaseFieldDefinition fieldDef = Rpt.Database.Tables(0).Fields("List_Name");
targetSortField(0).Field = fieldDef;
targetSortField(0).SortDirection = CrystalDecisions.Shared.SortDirection.AscendingOrder;
}
Thanks.

Anyone has any idea how can we establish a GPRS connection on a computer using a GSM modem. I know that creating a RAS connection would do the job and i am currently using the same method using RAS api, but i want to connect to GPRS through my application and establish a connection that other applications can use.
Something just like the dialer software that come with the GSM modems.....so any ideas on this one?

The differences are only in AT commands. Just look at the AT commands from your GSM modem.
|
|

|

yes, i know about AT commands also, but how will windows have an available connection. Have tried to send AT commands to the modem, the modem was connected on GPRS, an IP address was also assigned to the modem, but how will applications in windows would use that connection.....

...and I fail at it  And somehow I can't get a working answer on Google.
I want to store an in-memory generated assembly in the database for future use. I create this assembly from generated C#. For some reason, I can serialize the object, it generates a nice byte[] which is stored in the db. But when I want to retrieve the assembly for deserialisation to my object, I get an error like
"{"Unable to find assembly '9-onzk69, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'."}"
My serialization routine is:
public byte[] Formula2ByteArray(Compiler.CompiledFormula formula)
{
byte[] result = null;
try
{
System.IO.MemoryStream mStream = new System.IO.MemoryStream();
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter =
new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
formatter.Serialize(mStream, formula);
result = mStream.ToArray();
}
catch (System.Exception ex)
{
throw ex;
}
return result;
}
And my deserialisation code is:
public CompiledFormula LoadFormulaFromAssembly(byte[] array)
{
try
{
Compiler.CompiledFormula formula;
using (System.IO.MemoryStream stream = new System.IO.MemoryStream(array))
{
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter =
new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
formula = (CompiledFormula)formatter.Deserialize(stream);
}
return formula;
}
catch (System.Exception ex)
{
throw ex;
}
}
Both the application which saves it into the db and the application which uses it contain the same libraries, so the objects-structures are known to both apps. De serialisation/deserialisation routines are in the same library/class working with the same object model.
What am I missing? If I do something stupid, just tell me

The answer might be stupid as well
Just a thought, if you need to Serialize an object shouldnt that be marked with the attribute "[Serializable]"?
Hariharan.T

|
|
|

The relevant classes are marked as Serializable, as otherwise the error would be notifying me which class is not serializable. This is not the case however, thus the serialize-attribute is set correctly.

Can you modify your deserialization code a bit to narrow down where an exception is thrown?
i mean seperate try catch for deserializing and one more for the type casting to find when it fails

"formula = (CompiledFormula)formatter.Deserialize(stream);"
This is the only deserializationcode I have, since I let the framework handle it.
I'm suspecting the name '9-onzk69' is the name of the temporary file created by the codeprovider which compiles it, but I don't know for sure, as a system wide file search comes up empty.
The stack trace of the exception is:
at System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembly()
at System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAssemblyInfo assemblyInfo, String name)
at System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable)

The InnerException is null.

My guess would be that it is having problems with the "special" characters present in those languages.
Are you using the Encoding.UTF7 or Unicode to do the encoding?

HI
Can anyone help me, creating a bar chart using crystal reports
it's uses a simple Database table
TableName|WaiterResponseTime
Table 1 | 30 seconds
Table 2 | 20 seconds
i want the graph to show thable name on the x axis and Waiter Response Time in seconds on the y axis
i got this working fine, however it's not displying the seconds correctly, i think it's doing a count and showing how many times a table appears in the database instead of displaying the corresponding seconds value
thanx in advance

I have a simple C# exe. It internally has some calls to custom interop. I dont have any problem in executing it manually by either double clicking the exe or thru command prompt, everything works as expected. But the moment i launch it using windows scheduled task it always fails.
It fails with the following exception,BTW i am using W2K.
Error: Unable to cast COM object of type 'Interop.DynamicDCOM.RetPointerClass' to interface type 'Interop.DynamicDCOM._RetPointer'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{8E3511C2-23CE-4098-92DC-D86E8C26ECF3}' failed due to the following error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
I have the right user permission to run this task, same as windows logon, also member of administrator group on the box.
Any suggestion/solution?
Thanks in advance....

I know it's a short answer, but I think that Colin[^] may have a point. And it would seem logical to verify his statement and answering his post.

Thanks for the reply!!!
just got it fixed  The issues is the component service running on the machine didnt have the Administrators group in the Default Security -> Default Access Permission. Adding it resolved the issue.

I am looking for a solution to converting a byte array to an image using the compact framework(windows mobile application). I have tried multiple ways, but the restrictions of the compact framework are proving to be very difficult because the Image.FromStream is not part of the

Hi,
did you tried to save the byte-array into a file, and loading the image from file. Maybe that's just a nasty hack, but it will work until you find a better solution

i m giving the code code and i m getting just "Exception".i cant understand wht exception is it.sometimes i m getting outofmemory exception.the line that throws exception is
pictureBox1.Image = new Bitmap(File.Open("\\Program Files\\syswifi\\pic\\screen.Bmp",FileMode.Open,FileAccess.Read));
this line raises another exception too "the process cannot access the files \Program Files\\syswifi\\pic\\screen.jpg because it is used been used by another process"
System.IO.MemoryStream ms = new System.IO.MemoryStream(data);
try
{
FileStream fs = new FileStream("\\Program Files\\syswifi\\pic\\screen.Bmp", FileMode.Create);
ms.WriteTo(fs);
fs.Close();
ms.Flush();
ms.Close();
pictureBox1.Image = new Bitmap(File.Open("\\Program Files\\syswifi\\pic\\screen.Bmp",FileMode.Open,FileAccess.Read)) ;
}
catch(Exception ex)
{
MessageBox.Show("Failed to display" + ex.Message);
}

hmm, are you sure that it is this line? it is trying to access a jpg...
I would call the fs.Close after ms.Flush, so that the data can flew into the FileStream.

Bitmap has a constructor that takes in MemoryStream as parameter. Something like this:
MemoryStream oMemStream = new MemoryStream(yourByteArray);
Image oImg = new Bitmap(oMemStream);
Does this works with Compact Framework?

its giving an exception "value does not fall with in range"

Can you show some code you have written and the line giving error?
