VB 6 To .net - Converted Project Takes Too Much Time To Load

Nov 22, 2011

I upgraded vb6 project to vb.net. Conversion of 3 user controls from vb6 to vb.net have done. Some converted code contains code like:

VB6.TwipsToPixelsY(LedHeight)
MyBase.Width = VB6.TwipsToPixelsX(VB6.PixelsToTwipsX(LedCol(0).Width) + 15)

The converted project takes too much time to load than previous vb6 project. What manual changes to the code should be done or is there any other option. Is it due to vb6 to vb.net conversion.

Large Database File (mdb) Takes Time To Load In .net So Alternative?

Feb 8, 2011

I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large

So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?

Asp.net - Inserting Records From Multiple Computers In The Same Database At The Same Time In SQL Server 2005?

Nov 12, 2010

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.

Make A Program That Takes Old Records From Access And Moves Them To MySQL?

Feb 2, 2012

I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".

Form Takes Forever To Load?

Aug 3, 2010

Ok, this might be something stupid that im not doing right, but here is my problem. Im moving from my 1st form, a small window, into my second form, that is full screen, but it takes like 4-5 seconds to load the full form. It sucks because during this 4-5 second load time, parts of the form at transparent and it just look bad. I think it might be because i have around 35 labels and a few other objects on the form. Does anyone know a way to make this not happen? Im in VB08.

Make .net Takes Two Arrows Keys At The Same Time?

Jun 1, 2011

in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

VS 2008 - Anyway To Time How Long It Takes A Message Box To Pop Up?

Sep 9, 2009

I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:


[code]...

this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?

Basically, It is a program that allows you to automatically click things.

Here is the

What I wanted to do was make an option to have variations in tick time. I want to put in a check box, and if it is checked then there will be 10 "variations" in click time, ranging from 1 second too soon, to 1 second late.

Binding DataGridView To TableAdapter Query That Takes Parameters?

Aug 3, 2009

I'm trying to bind a datagridview to a tableadapter which contains a query that requires parameters (for the WHERE statement of the query). The datasource is a SQL Server database. When I bind the datagridview in design view, it does not let me choose which tableadapter method I would like to use. The way I've been fixing this is to go into the code behind that form, where Visual Studio puts in some auto-generated code that fills a datatable in the dataset and I change the method that it's using there and put in my parameters. I don't think this is the proper way to do it, however, especially because sometimes that code doesn't even get generated! My other solution is to just programatically bind the datagridview to a datatable which I have filled using the tableadapter. This seems like more work than it should be, though.

Reset DataGridView Blank Row If User Clicks In That Row And Takes Focus Off That Row

May 19, 2012

If a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.

Is it possible to tell the DataGridView to un-mark this row as being changed?

Is it possible to reset this row when focus is off the DataGridView?

We are using the following event handler to alert the user if the Invoiced On is left blank:

Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _
Handles DataGridViewPayments.CellValidating

[Code].....

Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.
