App Makes Use Of Many Queries And Commands?
May 6, 2010
I have a data driven application in <acronym title="Visual Basic">VB</acronym> which works with an SQL Server 05 Database.Since this app makes use of many queries and commands, occasionally i'me getting a timeout error as the connection pool is full. So i figured that at a specifc point in time within the app,i'll clear the connection pools using the ClearAllPools method rather than increase max pool size.
I'm using the performance monitor on my XP development machine (NumberOfPooledConnections) however not once do i see the number of Pooled Connections reset to 0 even when that method is called.How can I determine that my solution is working (if it is) before I deploy the update?

In Visual Basic 6.0 Professional, on some of my programs (probably the simple ones) the File drop-down menu Make option has .vbp instead of .exe extension. How do I force it to compile?

I just tried fooling around with a "windows forms" project, and I would like to see the code that creates the form. How would I go about looking at that?I can only edit the code that would occur from GUI events.

I am writing an application in VS2010 using VB.net.The application is relatively simple and I would expect the .exe to be less than 1 Meg.I have written a couple of applications that are quite a bit larger that are less than 2 Meg.I am compiling in "Release" mode.The file size is 29,127 KB (in debug mode it is just 29,167 KB)Where do I start looking to find why the .exe is so large?

In a function I have
Do Until PageLoaded() = True
{
Nothing
}
The problem is it freezes up the program and makes it unusable. I fixed it using timers but it makes my program real sloppy and hard to edit.

i have a problem.. i use this code to download:Dim dl As New System.Net.WebClient dl.DownloadFile({online_file}, {local_file})now, it does download the file. my work is done. the only downside is that, until the download is finished, the program crashes!if i download a 5kb .txt file, all is ok, you wouldnt even notice
if i try to download a 15MB .rar file though.. now the program crashes for a long time! when the file is fully downloaded it works just fine again.how can i make it so that downloading doesnt make the application non-responsive?(and if possible, how can i make it see how many kb is downloaded? like at this second its 15kb of 2048kb)

Is BindingSource class makes use of Threading to read and write the values in controls and in objects?I mean how bindingsource know when properties of an object changes and sometimes seems not to know? Does it use a kind of BackGroundWorker running to watch changes on bindings objects? And why does it sometimes read and write properties so many times the same value on the same object's property?I found that it's sometimes easier not to use them since it's hard to know why a control do not update but, on the other hand, dealing with control events can be tedious. And what if i tried to make my own BindingSource Class not inherited from the System.Form.BindingSource

I have a custom NumericUpDownColumn in my DataGridView. Problem is that when I type in a 0 in those cells it automatically changes to DBNull, this causes all sorts of problems with other code. I found the code for the custom column through a google search and don't know enough code to actually go through it and fix the problem myself. If I change the column to a TextBox column instead, it shows a 0 instead of DBNull and everything works as it should. So I figured the problem must be within the code for the custom column. Here's the

Is there any way to change the sound MessageBox makes when it appears? I've written a Hangman game that displays a message box when a player wins, loses, hits an invalid key, or presses the same key twice and it always makes the same sound.

how to make a program that makes all the possible characters and numbers (A-Z & a-z & 0-9) from 5-20 characters, and put them in a list or something?
Someone may think this is bruteforce hacking, but I don't see why I should do that? If I want to find a password on 13 characters, it would be: 62^13 = 200028539268669788905472 possibilities... in other words... it would take forever!

i have an access 2007 database in wich i have a table named abc_PersonalLog, wich also has three columns: Id (auto number), StarDate (text) and LogEntry (Memo). It is a Diary application. So, when the user makes a log entry, the StarDate column receives a string formed of concatenated year, month and day, i.e. if date is 20th march 2012, the string will be 120320, and the Log entry column, the text entered by user in a textbox.My problem is that, somehow, i have to retrieve that data, when the user will want to read log entries he made. I managed to assign the text property of a label to the LogEntry text for a given date.But, if the user makes multiple entries in a single day, the table will have several rows containing the same string in the StarDate field, but different text in the LogEntry fields. How can i display ALL the LogEntry texts for all the rows containing the same StarDate value? Here is my code so far:

While codes are working, when it is the time to create table, form appears and user inputs the datas and press OK button and table is build according to these datas in MS Word. Does anyone has an idea ?

No problem so far. I use a Timer in the Usercontrol to make some sort of Fader. No problems there either. BUT I also added a few labels. In the Timer Tick I type the following lines:
