CONCEPT - Control The Message And The Ads
Nov 7, 2008A commercial application we are selling can display a User control written in VB.Net in the interface. I am writing a vertical strip that will display some of our ads to our customers. I would like to be able to control the message and the ads. My idea is to upload an XML file to our server, then have the Vb.Net add-in (user control) download the XML file to a temp location and display the contents as advertisement. 1. Is that a good way to do this? I am open to other suggestions. 2. Is there a way I could embed javascript inside user control? I want to be able to animate the text displayed if possible and I dont know how to do that in Vb.Net user control.

View 3 RepliesReplace Registered Dll Concept?
Jul 22, 2009I am replacing a VB6 application with a rewritten counterpart in VB.Net. In the VB6 app there was a 'control' application which presented a form to the user and allowed them to select a 'client' from a drop down list. Selecting a client caused the reading of an ini file which set client-specific parameters, including the program names of several dlls, which were also written in VB6 and registered on the subject machine.
For example, each 'client' had a different letter format, and the letter was written by the selected dll. This made everything late-bound, but there is only one user. Most of all, it made it convenient to continually update individual letters by updating only that dll, and dropping the dll on top of the old one. Thus the (clerical) user had only to be told to save this file to the usual folder. I could have compiled everything together in one exe, making my updates larger and more complex.
In re-doing this in VB.Net, how should I replace this sort of approach?
I could tie everything together in one big project (and compile it to an exe which is the large update I was avoiding). Should I just do that? If I continue with the approach of having my client-specific (.net) dlls compiled separately, does this make sense in the .Net world? How do I call them? Do they need to be registered as they were before? What's the right way to do this and still give me the flexibility I had?

View 2 RepliesIDE :: Creating Data Entry System For Local Community Group?
May 14, 2011I am trying to create a data entry system for a local community group. I am working with VB.NET 2010 and MSAcess 2000. I am completely new to using a DB in VB.Net. I have created a form with the membership table bound as details on the form and the classes they are attending as a DataGridView. I used all the Visual Studio GUI tools for this. It was reasonably straightforward once I got the hang of things. My problems arise when I try to ensure that a user cannot move to a new record or create a new member without first saving any changes they have made.
I am using ColumnChanging events in the ...DataSet.vb class to set flags to indicate whether any data values have been changed on the form. My problem is that the ColumnChanging events for the classes DGV fire immediately on changing the data whereas the ones for the member details don't fire until I start to move to a new record. I don't know if it is important but my member navigation is achieved by means of a combobox on the form that lists the member names from the table. I have absolutely no idea why this works - it just did; the form updates as soon as the user selects a new member in the combo box.
Summarize And Group Access Data Records In Excel Report
May 25, 2009I am looking to produce an Excel report from an Access database table. The data contains numerous records with fields for Site, Country, Region, Type and a Resolution Time. My problem is that each month the Sites change so I need to be able to write VB code within Access to read the database table and output 'Site' records for that month, grouped together along with the incident details for that site, e.g. The report would have the following headings:
'SITE' 'COUNTRY' 'REGION' 'TYPE' 'TOTAL' 'RESOLVED<3DAYS' 'RESOLVED>3DAYS' 'NOT RESOLVED'
MEL AUS APAC TECHNICAL 78 40 31 7
MEL AUS APAC HARDWARE 49 40 8 1
LON GBR EURO HARDWARE 90 40 40 10
As I will have over 30 different sites and these may change each month how do I loop through the data identifying each site and its associated field values? I have used the following code to open the data and loop through records printing to excel, but am stuck at grouping by site:
Set rst = db.OpenRecordset(sqlStat)
row=10.......
..... Do While Not rst.EOF
.cells(row, 1).Value = rst.Fields(0)
.cells(row, 1).Value = rst.Fields(1)
.cells(row, 1).Value = rst.Fields(2)...
Grasping The Concept / Context Of Two Dimensional Arrays?
Oct 29, 2010I am having difficulties grasping the concept / context of two dimensional arrays. For the assignment I am working on I am required to use radio buttons to allow a user to vote if they like or dislike an item from a combo box. The contents of the combo box have been populated through the IDE via tht item property.I understand how to set up my rows and columns, which will be, (0 to 4), (0 to 1). The trouble I am having is how to record and display the votes and have them correspond to the selected item from the combo box. Can anyone give me an example of how something like this works?

Possible To Achieve Performance Tuning With Same Thread Concept?

With that we simultaneously keep track of the incoming files in each folder.Currently, we are facing an issue whenever we receive multiple files of bulk volume, parallel processing of the files getting delayed with thread concept or failing sometimes.We need to implement the same logic with some other concept avoiding multi-hreading. Or is it possible to achieve performance tuning with the same thread concept?

Duplicate Concept, Industrial Simulation Program To VB Conversion?
Jul 19, 2009I am trying to convert an industrial simulation program to a VB program There is one hard concept that I have problem with, it is called "Duplicate" Ex: When 1 person pass the duplicate block A, then 2 persons comes out, (that person is cloned). 1st person goes path 1, has delay time of 1 hour. 2nd person goes path 2, has delay time of 2 hours. At the end of the 1st hour, 1st person arrives at the detour, at the end of 2nd hour, 2nd person arrives at the detour, but 1st person already moves on to the next task for an hour.
So you can consider them doing their separate tasks simultaneously. Then complication comes in when somewhere down the path, 1st and 2nd person pass another duplicate B, then total of 4 persons will run into their own separates paths and delays. Then they will come back to the starting duplicate block A, thus creates total of 8 persons and follow the same path above again.
Until some condition has been met (ex: total number of persons pass through duplicate B), then all of them will leave the system.Anyone has any idea what is the best way (logically easy to follow) to program the concept? I hope I explained it clearly. It's unfortunate that MSDN doesn't allow attaching image or video.
