I made a query for inserting a value from text box to MS ACCESS db
sql = "INSERT INTO Equipment (port_number,display_name,equipment,tonnage,user_privilage) VALUES (" & CLng(txtPort.Text) & ", '" & CStr(txtDisplay.Text) & "', '" & CStr(txtCA.Text) & "', " & CLng(txtTonnage.Text) & ", '" & CStr(cmbUser.Text) & "')"
Actually I meant for inserting the data entered in the text box, but now saving is the code itself i,e; in port_number column 'CIng(txtPort.Text) ' will be saved
A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
I have tried several solutions:
1) data.SaveToFile "/temp/"&filename, 2
Error: Object required: '????????????????????'
???
2) File.WriteAllBytes "/temp/"&filename, data
Error: Object required: 'File'
I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!)

This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
I think I'm over thinking this, but I'm not sure where to start.
Sub SaveDocument() Dim outputFile1 As StreamWriter 'Object variable
Try'Create File outputFile1 = File.CreateText(strFilename)

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data
So here is the error...
An error occurred while saving the Panel. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.ThrowHelper.ThrowArgumentOutOfRangeException() at System.Collections.Generic.List`1.get_Item(Int32 index) at PanelController.Save(Int32 ID, FormCollection FormValues)
During debugging, I checked the parameter it was adding to the save stored proc, and the ID it was adding was 0. Then, when it used this
oDal.Execute("Lending.uspPanelSave")
Item.PanelId = oDal.Parameters("@PanelId").Value
To retrieve the ID to return it, it set it as 1000? Anyone know what the problem is?

View 6 RepliesI have a table in SQL Server with a field defined as Varbinary (MAX). In VB I am trying to save an image to the table. The file I'm using is 139kB in size and I get no errors but when I look at the record, the Attachment column where my image stream should be is empty. The rest of the information is saved. I checked the buffer and it grabs the correct size of the file (141475) so I'm very sure it's found and loaded the image.
Could the parameter from the SQL not be passing the binary value to the parameter properly?

We are developing applications using VB .NET as front end and SQL Server as back end. We want to store and retrieve pictures in a database. We do not want to store the pictures directly into the database but rather the path of the pcitures so that through the same paths we can retrieve them.
View 14 RepliesI have a asp.net website. The asp.net website connects to a wcf service. The wcf service is using a sts(security token service) with custom username/password authentication. The asp.net page has a simple username and password login form. Now I'd like to implement a "remember me" function. At the moment I have two solutions: Saving the entered user and password on the asp.net server and set a cookie with an ID. Saving the STS token on the asp.net server and renew it if needed. What is the more secure solution? Do you have any other ideas?
View 1 RepliesI have been learning a bit of jQuery and .Net in VB. I have created a product customize tool of sorts that basically layers up div and add's text, images etc on top of a tshirt.I'm stuck on an important stage!I need to be able to convert the content of the div that wraps all these divs of text and images to one flat image taking into account any CSS that has been applied to it also.I have heard of things that I could use to screen capture the content of a browser on the server which could be possible for low res thumbs etc, but it sounds a little troublesome! and it would really be nice to create an image of high res.I have also heard to converting the html to html5 canvas then writing that out... but looks too complicated for me to fathom and browser support is an issue.I'm thinking perhaps I could do with two solutions for this. Ideally I would end up with a normal res jpg/png etc for displaying on the website, But also a print ready high res file would be very desirable as well.

View 1 RepliesWhat I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.
