Yeah, you can also do "many important reports" by doing it the correct way. Sure, the SQL is a little more complicated, but it's a LOT safer for your data.

What you should be doing (as Dave implied) is redesign your table structure so there is 1 MRP field on your product table and a related table containing the history of the MRPs
lnkProductMRP
ProductID int
MRP Double(15,2) (why is this 2 decimal places and not an int)
Modified DateTime - when it was changed
ModifiedBy varchar(##) - who did the deed
Reason varchar(###) - Why the change of MRP
This retains your history past 3 events, allows roll back, and records the person and reason for the change.
Never underestimate the power of human stupidity

I have been searching the far reaches of the web trying to find a way to import all of my rss feeds into openoffice base. From what I have gathered so far is that it is possible with VBA code but could not find it anywhere. I think this should not be that difficult.
Also, I have been trying to find a way to forward emails to same database. Is there a way to setup a database email address to send mail to? I have already tried to forward the emails to rss feed but that is not without errors.
Please assist me in anyway, thank you.

Show us some code, for each of the two questions you have. However, e-mails might not be sendt an masse, as some providers have rules on how many can be sendt as a SPAM filter.

Hello,
I would like to make a duplicate of the currently open document via a VBA macro.
That is, when running the macro, it will use the current active document as source and make a copy of it without saving it to a file.
The current document may be modified (changes were not yet saved to a file), and it could be based on a specific template, with headers/footers/fields.
The new copy, should have an identical content (including headers/footers/fields) as the original, based on the same template but with a new name and not saved to a file yet. (The user may save it later if required)
Is this possible?
Thanks in advance.

Perhaps something like this will work for you.
Sub CopyDoc()
Dim sourcedoc As Document
Set sourcedoc = Application.ActiveDocument
Dim newdoc As Document
Set newdoc = Application.Documents.Add(Template:=sourcedoc.AttachedTemplate.FullName, Visible:=True)
sourcedoc.Range.Copy
newdoc.Range.Paste
sourcedoc.Activate
Set sourcedoc = Nothing
Set newdoc = Nothing
End Sub

I have been working on a minecraft (game) launcher and so far everything is going good. But I want it to do something more.. like install different versions. The way the official launcher does it by reading the .json file. Here is an example of one of the json file:

I wanted to know how to read this (format it) properly. Example the above gets formated as:
-Djava.library.path=[]versions\1.6.4\1.6.4_TagCraftMC -cp []libraries\net\sf\jopt-simple\jopt-simple\4.5\jopt-simple-4.5.jar;[]libraries\com\paulscode\codecjorbis\20101023\codecjorbis-20101023.jar;[]libraries\com\paulscode\codecwav\20101023\codecwav-20101023.jar;[]libraries\com\paulscode\libraryjavasound\20101123\libraryjavasound-20101123.jar;[]libraries\com\paulscode\librarylwjglopenal\20100824\librarylwjglopenal-20100824.jar;[]libraries\com\paulscode\soundsystem\20120107\soundsystem-20120107.jar;[]libraries\org\lwjgl\lwjgl\lwjgl\2.9.0\lwjgl-2.9.0.jar;[]libraries\org\lwjgl\lwjgl\lwjgl_util\2.9.0\lwjgl_util-2.9.0.jar;[]libraries\argo\argo\2.25_fixed\argo-2.25_fixed.jar;[]libraries\org\bouncycastle\bcprov-jdk15on\1.47\bcprov-jdk15on-1.47.jar;[]libraries\com\google\guava\guava\14.0\guava-14.0.jar;[]libraries\org\apache\commons\commons-lang3\3.1\commons-lang3-3.1.jar;[]libraries\commons-io\commons-io\2.4\commons-io-2.4.jar;[]libraries\net\java\jinput\jinput\2.0.5\jinput-2.0.5.jar;[]libraries\net\java\jutils\jutils\1.0.0\jutils-1.0.0.jar;[]libraries\com\google\code\gson\gson\2.2.2\gson-2.2.2.jar;[]versions\1.6.4\1.6.4.jar net.minecraft.client.main.Main --username ~ --session - 0 --version 1.6.4 --gameDir| --assetsDir []assets
where ~ is username
[] and | is the %appdata% folder
I can format it manually using a notepad but this takes a lot of time and the process isn't automated. The above is an argument which needs to be passed in order to make the game run.
Any help regarding this would be appriciated

Dear sir,
I made a project in Visual basic and sql server table,i made a window form where i placed a data grid, in data grid the header and data populated from database table, but i want to change the datagrid column header (not database table column)and populate the data from table programmatically.
|
|

You change the column headers by aliasing the columns in your SQL statement
eg
SELECT Firstname as Forename, LastName as Surname FROM tblPerson

You want to use something like:
gridView.Columns("yadayadayada").HeaderText = "UseTheForce"
DisplayIndex is also worth looking at as it will allow you to re-order the columns.

dear all,
i want to read a dxf and extract entities data for polyline to be used later
i already read the dxf file but i do not have any idea how to extract the required section from it
my code was
Public Sub Dxf_Reader(ByVal file As String)
Dim tag As IO.StreamReader
Dim txtarray As String()
If infile = "" Then Exit Sub
tag = IO.File.OpenText(infile)
txtarray = tag.ReadToEnd().Split(New String(Environment.NewLine, StringSplitOptions.RemoveEmptyEntries))
tag.Close()
End Sub

Apologoes if this the wrong forum – could be in “Database”, or even C# - it’s a bit of a cross-over...
The scenario:
I have a database table holding records of items that are flagged according to various key terms held in another table – eg:
keywords table:
ID – integer
sKeyword – string
There are about a dozen of these, which won’t change, with ID’s from 1 to 12.
items table:
ID – integer
iKeywords – Double
(other fields)
The iKeywords number is calculated simply as the sum of 2 ^ keywords.ID for all relevant keywords. A record may be associated with multiple keywords. Thus it is easy to select records matching keywords criteria, and updating records is similarly easy.
The problem:
Give the iKeyword value of a particular item, find other items which are matched with some or all of the keywords of this record, ordered by the number of matching keywords.
The solution...?
Apart from an obvious brute-force approach, I am sure there must be an elegant algorithm (c# or vb .NET preferably) that can do it.... even better a really smart SQL statement, but that’s probably hoping for too much.
Or maybe I should be approaching the database structure differently?
|
|

|

Why is your iKeywords field is a double if you only have 12 keywords and they're not going to change? A 16-bit integer (smallint) would be sufficient.
The design feels wrong; the standard approach would be to have a many-to-many relationship between the keywords and the items:
Keywords: KeywordID [PK], Keyword
Items: ItemID [PK], ...
ItemKeywords: ItemID [PK, FK], KeywordID [PK, FK]
This would lead to a fairly simple solution:
SELECT
B.ItemID,
Count(1) As MatchedKeywordCount
FROM
ItemKeywords As A
INNER JOIN ItemKeywords As B
ON A.KeywordID = B.KeywordID
WHERE
A.ItemID = @ItemToMatch
And
B.ItemID != @ItemToMatch
GROUP BY
B.ItemID
ORDER BY
MatchedKeywordCount DESC
;
With your current implementation (updated to use an integer type for iKeywords), you can identify matching products using bitwise-AND[^]:
SELECT
...
FROM
Items
WHERE
(iKeywords & @KeywordsToMatch) != 0
;
Counting the number of matching keywords is slightly more complicated. For example:
WITH N0 (X) As
(
SELECT 1
UNION ALL
SELECT 1
),
N1 (X) As
(
SELECT 1
FROM N0 A CROSS JOIN N0 B
),
N2 (X) As
(
SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) - 1
FROM N1 A CROSS JOIN N1 B
),
PowersOfTwo (Value) As
(
SELECT Power(2, X)
FROM N2
),
MatchingItems As
(
SELECT
I.ItemID,
I.iKeywords & @KeywordsToMatch As MatchedKeywords
FROM
Items As I
WHERE
(I.iKeywords & @KeywordsToMatch) != 0
)
SELECT
I.ItemID,
Count(1) As MatchedKeywordCount
FROM
MatchingItems As I
INNER JOIN PowersOfTwo As P
ON (I.MatchedKeywords & P.Value) != 0
GROUP BY
I.ItemID
;

Many thanks for this - should be enough to get me going!
I used a double only because when I began I wasns't sure of the exact keyword list, so played safe in case there were more. I agree the design "looks wrong" as it is clearly limited to only a relatively small number of keywords. I'll have a play with doing it right!

Sir Please tell me how to run an external exe in a frame in vb.net... it is possible...

Member 10279246 wrote: external exe in a frame in vb.net
WinForms does not have a "frame" concept. You can change the parent of a running executable to point to your Window, as you already did. SetWindowLong[^] is used to change the border. The statusbar and toolbars aren't part of that border. The borderstyles can be found on P/Invoke[^].
..and please don't repost the exact same question. People tend to ignore duplicate posts.

Which part of "don't repost" did you not understand? 
You have now posted the same question twice in this forum, and twice in QA. You haven't even had the courtesy to respond to the people who have tried to answer your previous versions of this question.

No you can't.
You can, however, open and run an external program from VB.Net.
|
|
|
|
|
Actually, you can do that. It's not very nice looking and you don't have control over the application window nor with the application itself. The user can do whatever they want with application, including putting it back to windowed mode and moving it around inside your parent window, even to the point where they can't see the window any more.
