I have a problem that I�m sure will not be hard to fix for anyone who has been using CR for some time.
To start I have created a program in VB2008 that uses a MS Access data file, I can connect to it with no problem and can also add data and amend data, so all seems to work perfectly. I have published it and it once again runs perfectly on another/s machines.I have now a requirement for a number of reports so have chosen CR for this purpose. I have connected the report to the database and that runs with no problems at all, that is until I try to run it on another machine, it seems not to be able to find the database and comes up with a database Login panel wanting me to log in with a password and Admin name.
I feel it's properly a problem with the path to the database but if I modify the path manually it still won't work.
so im trying to do this project, and it gives me a a data file, and asks me to use stream reader to put it in the combobox, and when i click the selected items from the combo box, it fills in the textbox's with other information i retrieved from the datafile...Does anybody know the solution?? heres what i have so far(option strict must be on) Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
this gets all the Item names from the data file to appear on the combobox... now if i knew how to get the other information to appear in the textbox's when i clicked on it,
I've made a program that calculates the costs of a transport, wich to my own surprice works. Because the prices vary with the weight of the transport, extra services and delivery within the 3 countries of the Benelux (Belgium, The Netherlands and Luxemburg), I use an array. The array is filled with data from a textfile (in this case not *.txt but *.prc). The data in the datafile is presented as follows :
I need to add a row of data to an exisitng TextFile that is in Tba delimited format. My program currently used ADO to read and update the table but that was creating to many problems with varying 3rd party providers of the Text File.
I am inserting a record to a text file database using OleDb command Builder I am getting an error in one the fields could not insert .... expect type is decimal The problem is the column contains a mixture of Letter and numbers Ex:
I am using a VB.net application connected with a .mdf database file.The application is running successfully, and when I try to insert records its accepted.Everytime I close and reopen the application, new records from previous run disappear. This happens inside the VS IDE when I'm testing it.
What i got is a checkedlistbox with a list of text files, iam trying to search thru the text file and add to a listbox, my code works, But from 2 Txt files its returning 2 found and each txt file has 5 lines with excat names.
G:DevelopmentDOT NET DevColony_4ImagesBattenhallAve_Plan.bmpand i want to find and return the value after the last '' for example in the string above i would want to return:BattenhallAve_Plan.bmp
I am attempting to calculate a range of prime numbers determined by two user inputs (textboxes) I have the following code, but it displays nothing but zeros in the multiline textbox. I just need a bit of guidance here as to what is causing my code to show nothing but zeros.
Public Class PrimeNumbers Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim lowBound As Double Dim upBound As Double
I'm connected to an access database using VB 2008.. there is information already located in the tables. But what I am looking to do, is find the "SUM" of all the data in a certain column.
I'm trying to work out a bit of a memory leak and was hoping someone can assist. The below program is running fine except for one thing. 1. The memory leak. When I run the program and watch task manager, I can see the memory usage of the program starts at roughly 14 meg. Over a period of hours, that increases pretty substantially. Eg. at 6am this morning, it was at 14 meg, and by 3pm it was at 36 meg.In a nutshell this program takes an incoming stream of data which looks like this.
It basically parses the stream and places items into hash tables depending on the type of data. Eg. I have a hash table for latitude, one for longitude, one for altitude, etc.The key is always the hex code eg. in the first line above the key would be 461D3B.Essentially, as the data arrives in and is parsed and placed into hash tables depending on the type of data, I also have another hash table dedicated to keeping track of timeout times for that individual piece of data. The timer event fires and if the timeout is exceeded for that piece of data then it gets removed from all the hash tables.
I believe this is working. I've done heaps of debug output to the output window ensuring that items are being added to and removed from the hash tables successfully. Eg. ensuring that the hash table record count matches what I believe the number of active records should be.I'm at a loss what could be causing this memory leak though. I'm assuming i'm not disposing of an object properly, or not initializing/declaring it properly, but I can't work out what i'm doing wrong.One thing i'll mention though. The timer event occasionally comes up with a warning about the contents having changed during the For..Next loop. I don't think this will affect things though. As long as the hash table item count matches what it should be, I don't see that being an issue.

I am needing to locate a given set of numbers in a string, and have limited success, it is almost always finding the numbers that I want, but I need it to be more reliable.Below is a test program that I am using to test with and also 2 picures that may explain better that I can put into words.
I have a string. I need to check what characters it contains because certain invalid characters are causing my sql query not to work. In the query I select where SupplierName is equal to the string. I need to replace the invalid characters at database and vb level. But I need to know first what the characters are.
I got a situation where i have the first word only of a a child window and the rest of the name changes. I need to find this child window using findwindowex i think by not knowing the full name.
Searching the processes wont work since it is a child.
Alright, my program requires a folder to put the save files in, and it works fine to create it when I know where the program was installed to. I want to assume that everyone will install to C:/Program Files... however, one cannot assume. Is there a way for me to find out where the program was installed to ie. D:/WorkPrograms/ProgramHere, instead of the Program files? Specifically, is there some sort of code that I can run at startup to find where the program file is, so I can keep all the save files in there?
I am trying to find the position in a string of a perticular letter of the alphabet (Q), I have found a method to determine if the letter exsists in the string, but not it's position.
I've been practicing how to use Loops. So I'm trying to create a program where a user enters 10 letters and I have to find which character has the smallest ASCII value.
example: If someone inputs "qwerTyuio" my output should display "T"
Now I think I got my program to get the ASCII values of a string but I can't figure out how to compare each ASCII value of each character.
Dim str, y As String Dim x As Integer str = txtLetter.Text
I have a program I'm working on (a chance game) that has 5 random numbers generated. I need to think of an expression to check to see if three of those numbers are equal. The random values are not an array, they are 5 separate variables. I have the code written to compare if there are two matching ones, but am having trouble thinking past that. [Code]
I'm an intermediate student taking on a monopoly game for a summative project. I decided to simulate the game monopoly. The rules are the same as the board game, so the idea is that each "property" or board piece is a button. I will have variables for the players position and player totals. To indicate an owned property, I'll change the buttons to flatstyle and use the bordercolor property.
To indicate the player position, I change the text on the button to include "Player: " etc. The trouble I'm having is that each button is named based on position, followed by the name. ie: "btn1Start", "btn2BalticAvenue", so on and so forth. Now, once I roll the two die and gather random integers, I add the total to the player position. Now what I want to do is find the button that the position corresponds to.
Private Sub turn(ByRef playerPosition As Integer) Dim die1 As Integer = Int(6 * Rnd() + 1) Dim die2 As Integer = Int(6 * Rnd() + 1) playerPosition += die1 + die2 Dim button1 As Button = ?
I've tried various methods. Me.Controls.Contains("btn" & Position) is a boolean, so I can't make an object control class equal to that. Me.Controls.Find requires an exact name, so I can't do Me.Controls.Find("btn" & Position) because it needs the full name - each property has something else added on to the name (eg "BalticAvenue"). I want to set the button equal to the specific button based on the turn position, so I can update the text to include the player and allow him/her to initiate the property's effect (buy/pay rent/or chance cards).
Is it possible in VB .NET to find out if a form is loaded? Also, is it possible to find out if a form is shown at the moment? I think for the second issue it's enough to get the value of the property of the form: MyForm.Visible However, I don't know how I could find out if a form is loaded or not.
If I have an unbound DGV with hundreds or thousands of rows what is the easiest way to find any or all duplicate rows? ie. where the data in all the columns is the same in 2 or more rows.
Well I've recently discovered that trying to create a file with so-called 'illegal characters' will cause your application to crash.. How do I find these characters in a string and replace them with nothing?
The invalid characters are / : * ? " < > | if that helps.
Bit stuck on this one, have seen alot about how to do it just cant seem to get it right. I want to have 2 text boxes with times in them.. at the moment i have them on click events then it just runs a Now for the time and fills the boxes from the system time. But then i want the 3rd box to find the elapsed time from the 2 times in the previous boxes but i just cant seem to figure it out
