This is a simple yet strange (to me) problem.In one project I can add rows to a dataset by:
Dataset created dsWaterReadings and datatable inside it dtWater.
dsWaterReadings.dtWater.Rows.Add("value1", "value2")
In the other project
I have created the same dsWaterReadings and dtWater
Now if I type:
dsWaterReadings.dtWater it forces me to chose dtWaterDataTable and that does not have a rows property.
Using dtWaterRow yeilds even less properties. What could the difference be. All references are idential apart from System.Configuration (which I dont think is the problem)
Many thanks

ensure that you have the datatable adapter define in your program so it can bring forward the table you want to add rows on
for example
dim da as new da.DBdataadapter.table
dim dt as new dt.datasettable
this will ensure you can call anytable on your database

Hi. I'm making a treeview and the items on it are dynamically assigned a context menu and info about the node is used in an operation from the menu. My code works fine except if you left click item 1, then right click item 2, it opens the menu as if item 1 was selected. It only works correctly if you left click item 2 before right clicking it. Any way to fix this?
Have you tried the Krypton Toolkit? http://www.componentfactory.com/free-windows-forms-controls.php

|
|
Set the right clicked node as selected node in NodeMouseClick event.
|
|
|
|
|
use the context menu property of the treeview.

I don't see how the selection of font makes any difference.

First, This is not a right Place to Post your Question.
There is no Different if using different fonts for printing ,
it's all depends on your printer Speed.

A printer is hardware. There is a Hardware and Devices forum on CodeProject. That would sound like a good place to me. This is the Visual Basic Forum, it is where people normally post questions about VB, NOT about printers.

Hi, i have a form with text boxes for username, initials, and password on.
Also on this form are a few checkboxes which at the minute i simply want to save their state to SQL as true or false depending if ticked or not. The checkboxes or text boxes are not bound to anything, and are used only for creating a new record in the table.
There is a gridview below these boxes showing already created records.
The code im using to insert to SQL with is:
If String.IsNullOrEmpty(UsernameTb.Text) Then
MsgBox("You must enter a Username!")
Else
If String.IsNullOrEmpty(InitialsTb.Text) Then
MsgBox("You must enter users Initials!")
Else
If String.IsNullOrEmpty(PasswordTb.Text) Then
MsgBox("You must enter a Password!")
Else
Try
Me.UsersTableAdapter.AddUserQry(UsernameTb.Text, InitialsTb.Text, PasswordTb.Text, ApplicationsChkbx.Checked, AdministrationChkBx.Checked, CustomerSearchChkBx.Checked, CustomerFormChkbx.Checked, UnderWrittingChkBx.Checked)
'Update the Gridview and notify account created
Me.UsersTableAdapter.Fill(Me.WDA_SQLDataSet.Users)
MsgBox("Created user " & UsernameTb.Text)
'Empty all the text boxes and set check boxes back to unticked state
UsernameTb.Text = Nothing
InitialsTb.Text = Nothing
PasswordTb.Text = Nothing
AdministrationChkBx.CheckState = 0
ApplicationsChkbx.CheckState = 0
CustomerFormChkbx.CheckState = 0
CustomerSearchChkBx.CheckState = 0
UnderWrittingChkBx.CheckState = 0
Catch ex As Exception
MsgBox("Error will robinson, error")
End Try
End If
End If
End If
"AddUserQry" is a Query on the dataset for that table:
INSERT INTO [Users] ([Username], [Initials], [Password], [Applications_Access], [Administration_Access], [CustomerSearch_Access], [CustomerForm_Access], [Underwritting_Access]) VALUES (@Username, @Initials, @Password, @Applications_Access, @Administration_Access, @CustomerSearch_Access, @CustomerForm_Access, @Underwritting_Access);
SELECT ID, Username, Initials, Password, Applications_Access, Administration_Access, CustomerSearch_Access, CustomerForm_Access, Underwritting_Access FROM Users WHERE (ID = SCOPE_IDENTITY())
For some reason when i create a new record, it saves the check state as -1 for checked, and 0 for unchecked. the table columns are varchar(5) for the check boxes.
Using checkboxname.checkstate doesent work either - that saves the state as 1 or 0 (as opposed to -1 and 0)
On another form i made for editing existing entries, i have the same text boxes and check boxes, which are bound so they show the record details. when using that form to EDIT an entry, it saves the check box states as "True" or "False" as it should do.
Im completely stumped here, because if i create a new user it then breaks the gridview showing users, because it throws up error messages about "-1 not being valid boolean" when it attempts to render each check box in a grid view.
Has anyone got any ideas why this is happening? and how i can make the insert save the check box state as boolean? im losing sleep over this one, litteraly!
any help/suggestions much appreciated

Have you tried checkboxname.Checked?
It sounds silly but it at least has the virtue of returning a boolean value.

hi, yes im using checkboxname.checked if you look at the code snippet above. however it saves as -1 and 0
.checkstate saves as 1 and 0
.checked gives minus 1? strange isnt it?
hence why im so perplexed by it!
|
|
|
|

SOLVED: setting the column to bit fixes it, that way SQL converts the numeric value on insert.
Also Mycheckbox.checked.ToString() will work too, though thats having vb do the conversion not SQL server.

To fully understand this you'd have to go to the site and look at this documentation.

I have to convert this to VB. in C# it runs fine.
He deletes the default.aspx
Adds a folder.
Inside he creates his PageName.aspx as normal.
He then creates a Design_Page.aspx with NO code behind.
He copies out the Page Header from PageName and post it in Design_Page.aspx and now it will use the PageName.vb as its code behind as defined.
Fine with C#.
In C# he clicks on the buttons and it creates a click event.
In VB I do the same and it creates a click event. The problem is it says I need a WithEvents associated with it.
I didn't think it would work, but I would follow the error message and create WithEvents for them. Underlined errors disappear. Now Build error occur saying the handlers already have WithEvents defined for them.
What is going on????????
#2)
SPControl.GetContextWeb(Context).Web("Whatever") has a nullreference error pointing at Context.
In C# it just seems to ignore it because it continues to work despite Context not being assigned.
I can't contact the blog owner, because the forms won't let me. There is a login button, but there is no JOIN that I can see. I'd just like to ask him how to convert this because it is taking a lot longer than I anticipated.
I know the associations are right because again it works in C# and all I'm doing is converting. So the WithEvents issue is really confusing.
The nullreference might require me to go about it a different way in some degree because of the differences the two languages interpret null, nothing or not assigned.

I'll start by telling you what I have now...
My web page (using a Persits AspPDF.NET component - trial now expired) accepts PDF uploads and then processes those individual documents by stitching them together - forming a single PDF file. This works flawlessly and, in fact, is precisely what I was looking for - almost. You can view the page at: http://www.mulehide.com/downloads/data_sheets.aspx although the trial component that merges the PDF files is expired.
Now, what I want to do is, rather than the PDF's coming through as uploads, I want them to come through from a previous page and be posted to this page, then perform the stitch operation. Basically, I want to do the same thing but instead, select PDF's that are already on my web server, rather than off the clients machine. I tried a couple of different methods and failed miserably due to knowing absolutely nothing about VB code. And I mean nothing!
Ideally the previous page would have say, checkboxes, allowing the visitor to select the PDF files they would like to combine. These would then submit the page and create the stitched PDF. Even cooler would be to have everything on one page.
I'm not locked in to this Persits product. He refused to help at all with this issue even though it meant a multi-server sale for him and if another method of stitching PDF files is available, I'm open to it.
Any ideas out there? Code is below. Thanks!
Steve

If you're looking for a free PDF merger, I'd suggest PDFSharp[^].

Considering your question has absolutely nothing to do with the product or stiching files together, I'm not surprised you're not getting support. Your question has to do with getting data from one page to another. You should be asking in the ASP.NET forum.
The previous page would have to be rewritten to put up a list of files available on the server, let the user select those files with a checkbox and clic a button. That button click would then send the list of files to another class that would do the combining and return the completed file.
If you want the details on this process, ask in the ASP.NET forum...

Why is it ? Because it's good to know that there are people worse off than you ? VB6 was always crap, and it's been unsupported for some time. VB.NET would be a lot less like VB6 if a bunch of MVPs had not revolted, MS knew they had made a mess, and were looking for a clean slate.

Not really, just brings up memories. I don't have it installed at home pc at all anymore, but no matter what, VB6 was and i could say still is most complete of them all. .Net for me is far away from complete. Speed? VB6 is much faster, it might have simpler GDI, etc.. but speed is much better than in .Net (for controls, not it's actual computing speed), it was simple and anyone could use it, was perfect for learning. Since Vb1 for dos i was using it, it did not give all those fancy stuff like most other languages in that time did have, but, sure was better than delphi (or pascal, depending on era). It's just that it was compact, and runtimes ware small. And it always did his job.
Not only that, in VB6 a lot of times one would depend on APIs, now, with .Net, programers don't know what are APIs, they don't know there are windows dlls that give us some nice features, it's all managed now, so no one dares to subclass anymore. People underestimate VB (pre-.Net), it really was not that bad.
And IDE? .Net is so slow, while VB6 did have really fast IDE. Sure, it's much nicer to programm in .Net, it's nice to write OO code, also saves me hours of work with all built in functions. But, also, it makes me more ignorant, before i would write algorithams, now, if i need encrypton, i will just use the one built in, while in VB6 i wrote 10 algortihams by specifications, it was so much more fun. Servers? I now have a class with all this, but before when i was making SMTP or IRC server, i did not read MSDN, i would read specifications of windows API. So much more fun, now, it's only coding with what we have already inside, thats good, saves us time, but the fun factor is gone.
