View 1 RepliesI created a Report in Crystal Report Designer. In this report, there is a place for image. I want to insert image in the report at runtime (not desgin-time). Because in my application, there is a pool of image files from which a user can select image.Is there any function in .NET, that can insert image(.jpg) at run time in report from file
like---: i am atteching the file in my query....Attached image(s)
I have created an application using vb.net 2008 and for reports Crystal Reports Basic for Visual Studio 2008 but the problem is, when I run the application in another machine away from developing box, I get the Load report failed notice. I don't have any idea on how I should approach this issue. I tried installing the CRRedist2008_x86 and CRRedist2005_x86 but still the problem won't go away.

View 8 RepliesI'm converting a stream of bytes from a network packet into a specific struct, and vice versa. For example, when converting a short back and forth, my method looks like this:
myShort = buf(0) + (buf(1) * 256)
or the other direction:
buf(0) = myShort mod 256
buf(1) = myShort 256
When it comes to a 4 byte integer, after some experimentation I found that converting from the byte array to integer is done this way:
myInt = buf(0) + (buf(1) * 256) + buf(2) + (buf(3) * 256)
Basically adding two shorts together. I'm not quite sure to do the reverse of that, to fill the 4 bytes from myInt.
I am working on a mini project that requires me to take a 8 byte hex string that I received from the Serial Port and convert it into a Byte Array and display it on the screen.An example of the string that I receive is 01050001FFFF8FFB
I am currently using the System.Text.ASCIIEncoding.ASCII.GetBytes(str) to help me achieve this. However I realised that if this does not support extended ASCII so whatever byte that is > 7F, I will not get the right value.My current code is as follows:
vb
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim str As String
[code]....
I have a hexadecimal value
07A5953EE7592CE8871EE287F9C0A5FBC2BB43695589D95E76A4A9D37019C8
Which I want to convert to a byte array. Is there a built in function in .NET 3.5 that will get the job done or will I need to write a function to loop through each pair in the string and convert it to its 8-bit integer equivalent?
I have developed a windows application on vb.net 2008 and deployed it on client machine my crystal reports are configured through DSN to server everything is going fine om my development machine but on client machine producing is "Load Report failed" .

View 7 RepliesI am needing to write data to a usb device. The USB device uses a byte array (DataArray() as byte) to store the data. How can I assign a struct object (myStruct(0)) to the byte array. I run into the error "Value of type byte cannot be converted to 1-dimensional array of byte" when I try to cast the struct as a byte.
View 10 RepliesI'm calling a Windows API that gives me a byte array which represents a unicode string - the problem is that if I call Text.Encoding.ASCII.Get String on it I just get the first letter of the string. The reason for this is that byte array has an empty byte between each character. I've verified that removing these empty bytes resolves the problem by just using a simple For loop to add the bytes that do have a value in into a new byte array, then calling Text.Encoding.ASCII.GetString on that and that gives me the full string I'm expecting.I'm just wondering if there is any easier way of getting the working string though without having to do a loop and create a new byte array etc?
View 2 RepliesHow to convert memorystream byte array to csv file. I have GetExport method that converts rpt file to excelformatted memorystream and then returns that as a byte array. Is there a way to convert this byte array to a csv file? Due to some reasons I can only pass this byte array back to calling function.
Public Function GetExport(ByVal reportID As ReportID) As Byte()
Dim byteArray As Byte() = Nothing
Using expRptDoc As ReportDocument = New ReportDocument()

I am looking for something that will convert a byte array to a string and back, anything in-build that does it as this method would:
To string:
vb
Dim b = ByteArrSerialize(Obj, Compress, EncryptKey)
Dim sb As New System.Text.StringBuilder
For Each item In b
sb.Append(Chr(item))
Next
To byte:
vb
Dim b(0 To Len(TheString) - 1) As Byte
Dim bCount As Long = 0
For Each item In TheString
b(bCount) = Asc(item)
bCount += 1
Next

View 1 RepliesWhy I've choosen this forum (VB.Net) instead of Reporting is this seems not a matter of reporting. When I load the report normally, it works fine. When I export the report to Excel, it works fine again. After that when I tried to open the report again, it gives the error : "Load Report Failed" . I've to restart my application for make it work fine again.I'm using a Crystal Report Viewer control to load the report.
View 5 RepliesI would like to add an image to a crystal report at runtime.
I am currently doing this using a second data table containing only a byte field and then a blob field on the report. However this feels like a hack and if there is no data in the first primary table then for some reason the image does not show.
Is it possible to add an image with code or another method?
