Show The Final Results Instead Of The Results Real-time
Sep 28, 2010
I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
when i clicked the final button to display my results "as string" it still showeed the number?? here is the code i wrote, is relativley simple, but the theory doesnt make scence to me Basicly its a box with 3 lables, (first name, surname and age), 3 text boxes (for the user to input this info) and a button at the bottom called "display in message box" so when i click the button, it displays the users input in the form as a message box. [code] what i dont get is if i said to VB that vaiable "Complete" was STRING then howcome it still displays the AGE which is an Integer (a number) not a string??
Im a beginner in visual basic 2010 im making my first project i created form3 for the search function so i created 2 checkbox to give the user the choice to choose to search by name or by date or by both of them and i created a button search then i created a datagridview to show up the results so im confused now how to start my project. should I start it with if checkbox1 checked then.... or what?
last year i have written a simple application with a listview filled by a sql-server with patient data.When the application opens, then the actual month is displayed. Now i get the db-entries from last year not from this year.Here is the function:
Private Function getPatienten()As DataSet Dim selStr As String = "SELECT ID, Nachname, Vorname, Dauer, Fachbereich, Datum FROM tbl_station11 WHERE month(Datum) = month(GetDate()) ORDER BY Datum"
I have written a code which adds some information to a database. No problem with that since the records get inside the database. My problem is that the record I added always shows up on my Search. I tried changing the variables so that none will have the same names between the two forms but it still shows.Example:
1. I added a record of a book which has an id of 1, name of Cisco, and total of 50. I added it thru the debug function.
2. I added a record of a book which has an id of 2, name of Link, and total of 30. This time, I added it directly on the database file itself.
2. I created a search button which will show records depending on the input of the user.If I type "1" for the ID, the first record will appear on the datagrid. If I type "2" for the ID, both records will appear. If I type "3" which I doesn't have any record with, the FIRST record will still appear. To summarize it, the record that I added through the program itself will always show up on the query results, no matter what I type into.

What do i need to put in the search button so the words that i will put in the textboxes on the rightside will show the results on the left?thanks for the reply. i need some codes for pattern.. ll i found in google is searching in a datagridview. i dont know how to put them in textboxes.
Dim id As String Dim title As String Dim country As String
When I launch VB Help and do a search it shows under "Local Help", "Exception from HRESULT:0x8004032E". It lists three results under "MSDN Online", but the large field to the left of it is entirely blank. If I double-click blindly in that blank area it brings up various topics as if they were listed there but invisible. Further, the region under "Contents" is also blank, as is the "Filter by:" field. If I click the down arrow by the "Filter by:" field it brings up an entirely blank menu. If I then click outside the menu box it brings up a message saying "The selected filter contains an error that prevents it from being applied.". What's wrong and how can I fix it?
I uses datagridview for show query results from database which may have 0 to x number of rows. So I made calculation to calculate size of underlaying form and my datagridview dependable on number of matched rows. Underlying form is transparent and all of that looks like user control what appears and works just fine. But here is one issue: Every time datagrid have to grow, black square in that area is showed before datagrid is filled, what is not nice and surely unwanted. Did datagridview have some mechanism to freeze it and show data when populating is finished?

I have designed a window application that: check the contents of a folder for specific files (HTML)move files to a 'working' diretoryparse each file with webbrowser control to extract datacall webservice to collect additional data
The main form has a large ListBox that displays event messages. What I want is for the application to display the messages as they happen. What seems to be happening is that the application will do everything and then display all of the event messages at once at the very end. pointers on how to write code that will add event messages to the ListBox as they happen?
I'm making a program when the user clicks the button it displays the number of rolls it took to get snake eyes ( 1 on each dice) I have randomized it and in the Do loop it calculates until it gets the right code. I just need some help with the code that will display in a listbox the results that didn't get picked for snake eyes.
I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. How can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere. I think (and correct me if I am wrong) that it's gotta be something with DataGridView. But I don't know how to create and populate a datatable with the result of as Select statement, how to create a dataset.
I have a form that I will be using to copy directories of photos from memory cards to locations on a computer. I would like to add a progress bar to the application to show the progress of the copying in real time. This is the code that I use to copy the directory in the first place Dim SourceDir As String = SourceTextBox.Text Dim DestinationDir As String = DestinationTextbox.Text If System.IO.Directory.Exists(DestinationDir) Then My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir,) Else My.Computer.FileSystem.CreateDirectory(Destination Dir) My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir)
I am trying to run powershell script from VB and I want to see the output of the script as it is running inside a console application. With my script (shown below) when I run from powershell it shows "Command Sleep Starting" and then waits for 5 seconds and then displays the other text.
However, when I run from VB.NET program, the execution waits for 5 seconds and dumps all the text output at once. It doesn't execute first Write-Output command and then wait and then output as it should.[code]...
I have writen the code so you put the number of times you want to flip the "coin" and into a label the results show. I want it to show the % instead of the number of times that the side lands on.
This is what I have so far:
Private Sub value(ByVal count As Integer, ByVal tailscount As Integer, ByVal headscount As Integer, ByVal flip As Integer) Dim FlipCount As Integer Dim strflip As String
So i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database Option Explicit Function GetFilenameFromPath(ByVal strPath As String) As String
I have created a program that randomly produces simple maths questions and saves them to a SQL Server (SQL Server 2008 R2). The code looks fine and works if I step through the program. Each pass it creates a random question answer and saves them to the database. However, if I run it (Debug/Release), the program produces a question and answer but repeats it in the database.
I am having a SP run in my VB application every 10 seconds to check for any new rows that have been inserted to the database since the last check. What is the best way to do this? Most likely it will be 0 or 1 rows, but I am afraid at random times it maybe more than 1 and so I thought I would fill it in a DataSet, but I came in here to see if there are any other better ways. If dataset is the best way, how do I do a For Each Row in the dataset to process some VB code for each row?
Ok i have a query i use to parse an xml file to get an id number of a movie that allows me to get more detailed information about that movie from a database.Now the problem is the id is returned correctly with xml files stored on my hard drive (c:\desktop\movies)but when i try and parse an xml file on an external drive it dont get a hit on the <id>1123</id> node.
query Function movieID(ByVal directory) 'Get the movie name
I have setup an OleDbConnection and my query works just fine but the problem I am facing is that I want the entire query not just a certain row or column. I also would like to place this entire query into a blank excel spread sheet.[code]
I am running VB from VS2005. I just had to change a program to revises the logon info for a database. When I run build, I get success and there are no errors in the error page. The only thing I can think is that the first two times I ran the build I have the configuration set for 2 copies. It never bothered me before but some update may have come in and changed that. I reset it to 5 and that did not help. I closed VS and re-opened, no help. I created a new folder and moved the contents of the release folder out so that nothing was left. After running the build several more times, the release folder is still blank.
Im creating a search button, and want to put the results in a datagrid. I want to view specific records depending on the keyword inputed by the user. Im having errors when I use this query
I have a decent understanding of the logic, the content. I'm working on a puzzle and I'd like to write a short program. I'm looking to fill in the following variables: AB.CDE FG.HIJ (they're part of coordinates, and the puzzle is part of a geocache) The puzzle asks you to determine which numbers correspond to certain colors, like this:
[code...]
I need to define A-J as >= 0 and <=9. I also need to say that each color is >= 0 and <=9, but that no color can be equal to another color (purple ≠yellow, orange, etc). some number combinations won't work. Purple and yellow can't be 2 and 5 respectively, because that'd produce a negative number. I'm guessing that there will be more than one possible result. So how do I create an equation that calculates this.
What is the difference in the two blocks of code below? I expected them to return the same result, but they don't.
In the case where xml.@Type = "null", I want PatientMetricTypeID (a nullable Integer) to end up being Nothing.
Block #1: If()
In this case, it ends up as 0. It looks like Nothing is being treated as an Integer and converted to 0. I can sort of see why this might happen but not fully... I would like to understand exactly how this works, and if there is a workaround.
Dim PatientMetricTypeID As Integer? = If(xml.@Type = "null", Nothing, CType([Enum].Parse(GetType(PatientMetricTypes), xml.@Type), Integer))
Block #2: If
In this case, it ends up as Nothing -- expected behavior.
