I am extracting data from SQL Server to .csv file using VB .net. Some data in the database are separated by enter eg. They used an application to enter the data so when they entered in a list box the pressed enter to go in to a new line.
So, when I extract the data to .csv file, the data after enter they appear in a new cell and not in the same cell as the rest.
How can I remove the ENTER space using vb .net?

Either the code that produces the CSV file is incorrect, or the code using the file is. If the file is created and read correctly, a newline is perfectly valid inside the data of a field.
A field value should be quoted when it contains a newline. Example CSV data:
Id; Info; Time
1; Hello there; 2006-09-26 18:36:20
2; "This
is
a
perfectly
valid
CSV
file"; 2006-09-28 09:51:12
Note that the values in a 'comma separated value' file often is not separated by commas at all...
---
b { font-weight: normal; }

Look into the String.Trim[^] method to remove any whitespace characters from the beginning and end of a string before you write the data out to the CSV file.

How do i change the size of all the controls in the VB.Net 7.0 application
I need your help.
|
|
|
|
|
Do you mean at design time or run time ? I'll assume run time. If you set the anchor property on your controls, they will resize with your form. Otherwise, you can set the X, Y, Width and Height properties on the controls manually, if you need to ( you usually don't ).

How to add buttons in GIF format from net to application
I need your help.
|
|
|
|
|
Do you mean animated GIFs ? To do that, you need to download or write code that animates GIFs, there is an article on this site, but in C#, I think.
To load a standard GIF, Bitmap.FromFile will work fine.

New to programming, about 5 to 6 weeks of class.Question is what is the code for incrementl loops(to auto increment a primary key value)
This is what i want.
|
|

I nearly deleted two of your posts. Try to give your posts subjects that actually mean something, although you should mention the VB version in the text of your post.
You want to write a loop which increments a primary key ? A primary key is a value in a database, I doubt this is what you mean. Do you just mean a simple loop ? You've had 6 weeks of classes, right ? And google works on your machine ? Have you bought any books on VB ?

Yes i do want a code to help me increment values of a primary key in a database so as not to get an error on duplicte data entry.And yes i do have a well running Google interface.Both simple and complex code will do as i advance.
I need you help.

OK - when you create your table, use the word IDENTITY on the primary key, and the database will fill that value for you, incrementing it automatically.

How are you deploying ? I tend to write a little C++ app to run my MSI, install .NET and any other drivers I may need.

If I have understood you problem correctly, you should enter the following SQL command string:
"...WHERE ti.itemcode=" & i.itemcode & " and v.vendorid= " & i.vendorid & " and ..."

|
|
|
|
If you read the thread below, he's apparently tried that. I suspect he needs to post his code.

There is no where clause in this code. A few nested selects, however, this query will be slow, I would expect.
This is a SQL statement, the problem appears to be in the code which adds a where clause, and uses your variables to do so. Where is this code ? Does it exist ? Where does this SQL come from, is it a stored proc ? You've not posted any VB code, does this SQL get generated in VB ?

OK - you told me you were writing code. You're not, you're using some sort of wizard.
We're back to the point where the only advice I can offer is to write your own data layer, in code. Hopefully, someone who uses the stuff you're choosing to use can offer some other advice.
Here's an example that uses a stored proc:

Yes, the right way to do data access is stored procs, which take parameters.

Is this VB6, or by global do you just mean a public variable on a class ? Either way, this is bad design, you should do better.
I would suggest the best thing to do is to write your own SQL code ( which also means you can put it in a data layer where it belongs ), then you won't be fighting a wizard.

If you're just creating SQL, remember you're creating a static string, it's not going to be parsed. You need to make sure you're passing in the VALUE of your variable, and not it's name
s = s & " where bizdate<=" & cfrom & " and bizdate >= " & cto

OK - it's VB6 ? No, I would attack anyone who tried to put that on my machine 
Like I said, sounds like your playing with wizard generated stuff, this never happens to me when I deal with databases entirely in code, and the other bonus is, I get to have a proper data layer.
I don't know what the Microsoft data environment is, but it sounds hideous. Hopefully, someone else knows more and can give you more specific help for the approach you're taking.

Hello all,
Perhaps you can help me. I have a com object which I converted from VB6 to VB.NET. I am using this com object with other .Net applications without any problem. However, I am now trying to use this com object in some old ASP code which I have not yet converted. I want to use the com object because it contains some additional functionallity that the original com object did not possess. The ASP code works fine when calling the old com object. BUT..if I change the code to call the new com object, it takes a very very (60secs.) long time for the object to be instantuated. In other words, when the code hits the CreateObject line, it takes 60 secs to execute. The rest of the calls to the methods of that com object execute normally. What am I doing wrong? I am including code snipplets of both the VB.NET com object and the ASP page.
Thank you in advance.

Really, I don't think you're doing anything wrong, but I'm no expert on ASP. It seems that on that GetObject statement, the NET Framework has to loaded into the ASP process on the server. This can take quite a long time. Depending on the machine config, I've seen .NET 2.0 load times take about 30 seconds, so this could be part of your problem.
After the page successfully loads and gets through this code, try refreshing it or open a new browser window and load the same page. If the second browser window gets through the page quickly (or as expected), this is probably your problem, but unfortunately, I think you're stuck with it.

Is there a way I can change only the font size of the contents in a Rich Text box? I've tried using
MainTxt.Font = New Font(MainTxt.Font.Name, 12) but that still removes any bold, italics, etc.
Any thoughts would be greatly appreciated.
Thanks for your time,
Brian
