View 2 Repliesi am trying to redistribute my app that uses Oracle 11g:
Imports Oracle.DataAccess.Client
The problem i am having is that it will not run on a machine that doesnt seem to have the correct drivers that its looking for. When i install ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio on the test VM it works just fine but thats a 230+mb file to download and install! Not to mention that if the user already has Oracle 10/11g on their machine that it may mess up their current connections/etc by installing that setup file.Is there another setup package that i can install that only has the Oracle Data Provider for .NET 2.0 11.2.0.2.0 or whatever its needing from that ODAC 11.2 Release 3 file.

Is there any way to increase this limit of 101 warning you can see after compiling? I want to actually see the total number of warnings to get an idea how much work is there.

how many variables and controls (i.e. text box, listview, buttons, etc) can a VB program has without slowing down its performance?
View 2 RepliesI am moving from VB 6 to VB.net. Are there any practical or hard limits on the number of controls per form? If so, what are the limits?
Are control arrays still supported in VB.net?
My issue is that some websites only allow say 15 characters maximum to be used to create a user name where other sites do not. Currently I have one text box on the screen and a button, and a web browser that navigates to two sites.Site #1 has a cap of 15 characters max to create a user nameSite #2 doesn't have any maximum amount of characters to use.I am wanting to know how I can enter lets say a 20 character username into the text box and have the code set a max of 15 characters for site one and nothing for site 2. I was thinking that this could be done when passing the information from the text box to the text box on the screen with something like
Textbox1.Text.value.length= maximum 15
Site #2:
Textbox1.Text

What is the maximum number of executions in a while loop in VB.net that it will allow? Meaning, it is checking for a variable to equal some value, but that value never comes? How many times will it execute the code before it quits? Is there some way to set the maximum number of executions without terminating it programmatically?
View 5 RepliesI'm trying to figure out a good way of implementing a List(Of) that holds a maximum number of records.
I have a List(Of Int32) - it's being populated every 2 seconds with a new Int32 item.
I want to store only the most current 2000 items.How can I make the list hold a maximum of 2000 items, then when the 2001'th item is attempted to be added, the List drops the 2000'th item (resulting in the current total being 1999).
Thing is, I need to make sure I'm dropping only the oldest item and adding a new item into the List.
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same. i even deleted the files in this folder(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error.i found a article on msdn that states that its a source code issue.

I have been looking all around Bing and Google trying to find this, does anyone have an answer? How many line continuations will the compiler tolerate in VB.NET 2010 (.NET 4)?
View 2 Repliesi am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text
textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.
1) Is it possible to set the maximum number of characters that a string can hold?

Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.
I tried a masked textbox, but that means i have to set the maximum number of digits before the decimal too which is no good.

View 3 RepliesI'm developing an application, which will have a common db in a server (SQLServer db) and the client PCs will have my program installed - in a LAN.
So, my question is, when the users in the client PC wants to pass some messages (for eg: one of the user got a message from his boss that all of them are requested to meet him). That is, I want to implement a communication system through my app. It will be a common message system. That is, just like a shoutbox.
So, do I have to use a TCP based communication system or just use a timer to check the db for any new messages and display them ?

I am trying to create a server to send clients text on request. I am using a tcp listener to accept clients then send each client to a thread in a threadpool which deals with each client's request then closes the client connection. It seems to work fine but I would like to know how it works. Using the listen loop below I cant help feeling I should be sending some values to the threaded sub. How does it know which client each thread is dealing with?
Sub ListenLoop()
Looop:
Client = Server.AcceptTcpClient

with XP and Outlook it works perfect, with Vista it does not.
Any chance to get it running on all clients? The source is very simple.

I am programming a chat like application using Tcp. Now I have a probem. I am going to have loads and loads of data being transferred so I will have to use 4 seperate ports.[code...]
My problem is for me to use a maximum of 4 ports all together transferring data from the client(s) to the server(s) I will need 4 clients and 4 servers. I need to open 4 instances of 4 clients. I was going to put a client in a form and then when the client is running it creates 4 instances of that form but than there would be too much confusion going on. I think there my be a way to use Classes instead of forms.
