I have created a simple database programme in VB2010 Express. There is one table called stock_main_table and one 'child' table called Stock_issue_table. The main part essentailly holds the part number and the issue makes a record of each time that part is used. Its a one to many type arrangement.In the main table I have a PRI key called ID_Number and in the child I have a field called 'control'. The control has a relationship with the PRI key in the main table. So each time you create a new line in the child datagrid you retain the same number for that record. All standard simple stuff.
When I run the programme the main table comes up OK and the datagrid for the child comes up OK. If I add a record, I can add plenty of children to it no problem. The records all save OK. You can amend a record as well without an issue. The trouble comes as soon as you DELETE a record and then hit save. The DELETE seems to work and the records (parent and child) all disappear, but as soon as you try to save you get a The DELETE statement conflicted with the REFERENCE constraint error. I have tried and tried to fix this but can't.This is the full text of the exception, if anyone needs anything else then please just ask and I will post it. There is no code with this other than what is created when the dataset is dragged onto the form
I am trying to figure out a way to convert a pdf, that could have multiple pages, into a multi page tiff file. I realize there are 3rd party programs that could do this but I need to be able to do it through code. I found this code snippet but am having problems with it because I am missing namespaces, I think. I do have a reference to the Adobe Acrobat 10.0 Type Library.
HTML Dim FileName As String Dim image As String = "Image" AcroXApp = CType(CreateObject("AcroExch.App"), Acrobat.CAcroApp) 'Removing toolbar buttons from the user interface With AcroXApp .ToolButtonIsEnabled("SaveAS") [Code] .....

I am trying to create a multipage tiff from a series of bitmaps. The bitmaps are not saved I am creating them using graphics. The code goes something like this:
Dim info As ImageCodecInfo = Nothing Dim ice As ImageCodecInfo For Each ice In ImageCodecInfo.GetImageEncoders()
[code]....
The problem is I can see the first page, but no others. I have searched the forums, internet, etc., have worked on this for hours and am getting nowhere.
I have converted pdf file to Tiff file using 3-party software. When I open the new Tiff file using 'Windows Photo Gallery', I can view both pages of the converted file. However, when I open the the Tiff file in a picture box in my app. I can only view the first page. So, my question is how can I view multiple pages of a Tiff file in a picture box?
The source code for this task is here: copied the VB code to Break TIFF file with multiple pages to be displayed in a Picture Box. I did modify one line of code for testin¦
'Save the master bitmap MasterBitmap.Save("C:UsersmyselfDesktopxx.tif", info, ep)
when i try to do the following:lblTotal.text = gwGrid.rows.count()
i always get 50, which is the size of my page. how can i get the count of ALL records returned, not just the ones displayed on that one page?i also tried the Selected event on my datasource:
Protected Sub ObjectDataSource1_Selected(ByVal sender As Object, ByVal e As ObjectDataSourceStatusEventArgs)
If e.Exception Is Nothing AndAlso e.ReturnValue IsNot Nothing Then Dim dt As DataTable = TryCast(e.ReturnValue, DataTable) Dim totalRecordCount As Integer = dt.Rows.Count End If
I was working with this control to make multiple pages fit on 1 main window. When clicking a menuitem, the program will go to the correct tab. Now the problem is, i only have the 2 standard tabs.. NOTE: This is NOT the standard Tab control found in VB.NEt 2005 ! Does anyone know how to add more tab pages
Am trying to create a multipage (or multitab) user form and each one of page (tab) has several textboxes in it. After user enters the input in the textboxes, the data goes into an xml file. All I wannna know is, what is the syntax for getting inputs from a textbox on some tab say Tab1. I tried this,
" Dim Var as Double Var = TabControl1.Textbox1.text "
It doesnt work. "TabControl1" is the name of tabcontrol i have inserted and "textbox1" is the name of textbox, the value from which I am trying to read.
I am creating a multipage excel report in a single worksheet using VB.Net. I need to display group header information at the top of every page. check whether a cell is the first cell of a page or not.
I had a related question running on this in a different thread,but I was told to start a new thread since the original had gotten off the original topic. I am trying to scan multiple pages from an Automatic Document Feeder Scanner and combine them to a singlemulti-page tif file. I am using two different third party libraries to do this.The first library I am using is to scan the documents. It saves the files to the local hard drive as single page tif files. This library returns the file-names as they were saved on the hard drive. This part seems to be working as advertised. The sourcefor this including a video on how to use it is at:
Dim FileNames As Collection Dim FileArray As New List(Of String) Dim Mergename as String
I'm trying to convert a .bmp into a TIFF. Here's my attempt:
Bitmap bmp = new Bitmap("C:Documents and SettingsAdministratorDesktopDoc Folder\_f.bmp") bmp.Save("C:Documents and SettingsAdministratorDesktopDoc Folder\_f.tif", ImageFormat.Tiff)
It doesn't work. Debug feedback:
Name 'bmp' is not declared. (BC30451) Method arguments must be enclosed in parentheses. (BC30800) 'Bitmap' is a type and cannot be used as an expression. (BC30108)
I can use to convert several thousand PDFs to TIFFs. Free would be great but willing to pay if the cost is within reason.One requirement that many of the tools I have researched seem to miss is that I need to be able to do this in memory.I am working with PDFs that are stored as binary in a SQL database so through SSIS, I would like to pull that binary, convert to TIFF, then send it off to a webservice I will be working with via stream. Unfortunately, it seems that most utilities I have looked into expect the pdf to be on the file system and I would definitely like to avoid writing a temp file to disk to do this conversion. For me that ruled out GhostScript and pretty much anything that's based on it.Also, the PDFs I am working with are rather old (v1.3) so the assembly should be rather forgiving/flexible (PDFFocus errors out on all my PDFs but works fine with newer ones).Based on posts from StackOverflow, it seems like Atalasoft or PDF4NET might work but both are a little too pricey for me so I am looking for some additional suggestions. Given that this process will be embedded in a script task in SSIS 2008, this will have to be .NET.
i read the pdf file using following coding how to read the tiff file i tried tiff file not working
// Dim fileStream As FileStream = New FileStream(uploadfile, FileMode.Open, FileAccess.Read) Dim length As Long = postHeaderBytes.Length + fileStream.Length +
