We have a small VB.net application that basically pulls information from our dBase and then exports this information to an .xls file. From this .xls file, in house agents then manually update a third party listing service (which maintains our current inventory) with the information contained within. The information is very basic, consisting of, for ease of discussion, a 'Part Number', a 'Description' and a 'Quantity On Hand.'
Normally we update this information once a week, but, a newly revised contract with this listing service now requires a daily update to maintain our 'platinum' vendor status.The problem is that it can take quite some time to manually update this information. an automated process is in dire need. And I have finished most of the ground-work and coding - up to a point. Hence the question, and hence where I get stuck.The listing service has provided us with the following WSDL's: One for Increasing our Inventory, one for Decreasing our inventory, one for Adding inventory and one for Removing Inventory.
Up to this point, I have re-programmed a Stored Procedure that was generating the exported information. this SP now does some internal math to figure out if a transaction result occurring on 'yesterday' was an 'Increase', a 'Decrease', an 'Add' or a 'Remove.' These results are then added to a result table under a newly created column named 'SERVICE.' This new information is then pulled from the dBase with vb.net and imported into a Data Table for analysis.
With this Data Table, I can now loop through each row, looking in the column 'SERVICE' and depending on the information contained in that cell, call the appropriate web service.
[Code]...
I realize that this has become quite long winded, mostly because on any given day I have 25 FF tabs open and none of them agreeing with each other. To add another wrinkle; the WSDL's in question use a lot of complex types within complex types with, you guessed it, other complex types entwined.
I have an interesting issue that a client reported It turns out that the desktop application they are using is changing the times returned by the web service to their local time so it looks like the data is off. We're in UTC-5 while they're in UTC-8 so 8:00 AM is returned to the GUI as 5:00 AM which is causing confusion. I've done this riddiculousness to get around it for now:
Code:
Dim intOffset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now).Hours
'Substract 1 if we're in daylight savings mode

My wife wants me to create a cookbook application for her. I am going to use this as a learning experience (Otherwise, I would just buy her one).
The main requirements are that she can store her recipes thier ingredients and the steps involved in this SQL server driven program. She also wants to be able to view and print any recipe she chooses.
My question is how do I display the recipe in its complete form? I do not know how to use crystal reports, and automating Word is too time/resource consuming. So what are my options in VB 2008?

What I am trying to do is update a label with a value from a sql table using a combobox.this is a record from the table concerned
Species_ID (PrimaryKey) | Species | Genus_ID | Avg_Length | Avg_Height | Est_Weight | Diet_ID
1 rex 1
46 18 14000

On my form I have a combo box that is bound to this table with Species_ID as the Value Member. When I select a value from the combo box I want to update 3 labels with data from the Species_ID row corresponding to that value.
I have Data coming in through a serial port and it consists of pretty much all numerical values except for a few begining response characters. Its a Load Cell which spits out Tension in Pounds. I'm making a simple terminal program with the ability to log the Incoming Data for record keeping and data plotting. I want the incoming Tension to be displayed on the screen real time.I can get it into a text box and have it scroll indefinetly as it updates the data,but I'd like to keep it localized in one Label. I can display it in the Label but it wants to scroll down as it comes in. I want to keep it refreshed in one spot if that makes any sense. Heres what I have thus far. It will put it in the Label but wants to scroll like in the textbox. For example if I send #00F0 followed by a carriage return it replys back with whatever is displayed on the Screen which usually is the tension.it says "01TK 00.074 LBS" no quotes.. for a reply.I'm assuming it needs to be stripped down to just the numeric characters first.'here is what gets sent to the Load Cell to tell it to output data fast as it can to the serial port.[code]

but this does not work, the label does not get updated.
label23.text = DataGridView1.Item(column, row).Value
could it be because that label is on another tab from the DGV? should i reference the other tab?i tried TabPage2.label23.text = DataGridView1.Item(column, row).Value but of course it's not working.

How would I create a label that reports a file size at all times? Or, on a regular basis, say every 10 seconds or so.
In my form, I want a label to watch certain file sizes (logs, etc.) in case one suddenly becomes too big.
It is easy enough to report a static file size when a form launches, but changing it dynamically...I don't know how to do that yet.
The following example is generic and simplified for illustration purposes.
The file is C:Applicationapplication.log
The label might include:
("The application.log file is {0} bytes.",GetFileInfo.Length)
or something like that. But that would report a file size once and never again unless I quit and restart the form.
If any .NET concept is used, can you provide a link to the documentation or msdn stuff?

Form1.vb: Imports System.Threading
Public Class Form1
Dim trd As Thread[code].....
So, I have a form (form1) with a label on, this label simply reports the status of the thread.The thread begins the Class1.Main() sub, and I have a delegate setup to change the text propoerty of the label.Now,I know the label is created on the UI thread,so I assumed the delegate would work. However,it seems that it updates the .text property, but doesnt redraw the control when .Update() is called .What am I doing wrong?I have found lots of examples of delegates, but all run from within the same class. I want to use threads too, not a backgroundworker! This code is a "simplified" version of a project I am on, which is encountering the same problems
I have a shopping cart ListView control backed by a custom object that has methods for selecting and deleting. In the ListView, one of the columns is an ImageButton that is essentially a delete icon, with the CommandName parameter set to CommandName="Delete".
My issue is related to updating the shopping cart ListView on delete; as the delete method is stored in the custom business entity object, I am having trouble in terms of updating the calculations made inside the cart (we have deleted an item, so I need to recalc shipping, taxes, etc).

I have created an updater for my application. When the application starts the user can launch an updater that will check for the latest version. Download it and copy the files to where the installation is.
Everything works fine.
However, I am looking for a more robust technique. And I have discovered it is better to hash the files on the web server with a hash algorithm and then when they have downloaded use the same hash algorithm to compare the hash values. If they are different either the files were corrupted when downloaded or some modified them without permission.
However, my problem is where do I store the hash values? I was thinking of hashing the files, and storing all the hash values for each file in a text file, and my updater will download that text file.
I am not sure if that is the best technique to use of not? Is this the normal and best way to do this?

View 2 RepliesI started programming in VB2008 couple of weeks ago (I'm using the express version) and I'm getting stumped by this ridiculously simple problem. I am trying to retrieve varying parameters from an external application and display their values in real time on a windows form control e.g. a label or text box. I already know what class and methods to reference for that, however I can only display instantaneous values (unless I use a .click event handler, but thats foolish I want them displayed without my intervention) I tried writing a loop in form load event handler but that prevents the form from loading. I also tried a loop in another module but that doesn't work either.
View 2 RepliesI have an app that I'm trying to keep single threaded, mostly for reasons to do with simplicity of ongoing maintenance. I've structured it so that I can eventually multi-thread it if need be but I'd rather not at this point. It's semi-real time and does perpetual looping to display a number of different graphs and do various work with both the graph display and the work being hosted in their own respective objects. If you're familiar with the Windows dispatch manager it's that general paradigm run synchronously. And yee haw, it pretty much works at this point and runs fast enough to meet requirements by a happy margin. I have a cosmetic problem that I'd like to solve if I could. When I left-click and move any form around, my graphs stop updating until I release the left click button. I was thinking about a doevents somewhere in the click event catalog.
