Need Assistance With Method Of Converting To Specific Column Locations To A File
Aug 21, 2009
I am looking for any assistance on the best method to accomplish this task. I need to take a comma delimited text file, load it into memory, and then grab indevidual columns of data and export them to a file.[code]I need to for this project I ma working on grab ALL of COL C for example and export it and the data to that column to a file. Can someone provide me with assistance on the best and easiest method on doing this? I know I can do it with a lot of parse text's and many methods of using a listbox or arrays but I'd like to explore some options.
The below picture is generated by the following code:
Public Class Form1 Private Sub Form1_Paint(ByVal sender As Object , ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me .Paint
[Code]....
What I want to do is when I click on each grid on the form (Touch Screen), a tooltip of some stored information about the grid appears on screen. For example, if I click my mouse on square 6,8 then some stored information such as grid number, grid name, level...etc appears on the tooltip on the screen.
I have a xml file with three columns (A, B, C). I want to take column name from a text box - i.e (column A from text box) and display all the contents of that column in a DGV. I want to do same kind of operation with rows - i.e (any row no. from text box) as well. I manage to display all the columns of xml file to dgv, but not anything else.
Private Sub all_columns() Try ds.Tables.Clear() ds.ReadXml("abc.xml")
I created a program that logs incoming data to a serial device to a text file but the output is not what i really want, the data appends to the text file and looks like:
I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.
I want define where my application and user settings files will be located.I would also like to rename them.For example my project will have a number of folders located inside the application folder when deployed.One of those folders is labelled "Cfg" and i want my application settings files to be saved in there.This is including the user settings, i dont want to localize the user settings file as is done automatically (at least not at this stage).
My card program generates a text file AllCards.txt - I want to know when the first character in this file is identical to the 3rd, 5th, 7th, or 9th. In this case I would need A (1st char) checked against the 5 (3rd char), 5 (5th char), 7 (7th char) and 8 (9th char).
I have a generic question regarding file paths and user interfaces. I am trying to build a user-interface to accommodate various file locations. I typically build interfaces which deal with files on drives. As such, I use a directory tree for this. I usually work with files on local drives. However if I wanted to ensure that all file locations were dealt with I would want to ensure that I was accommodating files in all drives (local, network, mappped etc.). I am assuming that the treeview would support all of these drive option.
However if the files are on a sharepoint site or in some other type of enterprise content system, then am I correct to assume that these file paths will be URLs? If so, then am I correct to assume that a directory tree is not the correct control to use for these locations? Should I be providing a textbox to the user and prompting them to enter this URL? Or is it better to have the URL loaded into a ListView or ListBox (i.e. "My Connections") and then provide these as options via a dropdown box. I am trying to picture a typical user interface. Is it a directory tree AND a text box/dropdown box.
As things are now, I need my program to store x number of file locations. My first approach was to use an array, however as i do now know how many files there will be, i am forced to use redim preserve. That is not very effective and I have therefore started using a StringCollection.
or is there some smart way to store these paths, that I have overlooked?
I am doing setup project in VS 2008. I used custom action to select file from local drives. On the button click of custom action form, I am launching Open file dialog as ofdGetNetPath.ShowDialog When I run the setup on Vista, and click the button to open the openFileDialog, it hanged, form becomes non responsive and I have to cancel the setup.
on debugging I got following error "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."
so I used the following code:
Dim ofdThread As Thread ofdThread = New Thread(New ThreadStart(AddressOf ShowOpenFileDialog)) ofdThread.SetApartmentState(ApartmentState.STA) ofdThread.Start() Private Sub ShowOpenFileDialog() Me.ofdGetNetPath.ShowDialog() End Sub
now on button click, OpenFileDialog is shown but it is not showing Mapped drive or Network location... what should I need to do to show the mapped drive or network locations?
I am using this code to parse an html file for image locations:
Dim htmlDoc As String = IO.File.ReadAllText(path, System.Text.Encoding.Default) Dim Regex As New System.Text.RegularExpressions.Regex("img.*srcs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))")
[Code].....
How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.
I converted a Vb.Net Form (which was previously written in vb6) with sharpdevelop to c#, now i am getting error that no suitable main method can be found.
I have a program that must copy a file to 3 locations, the local hard disk, a USB drive, and a network location. I have the file (about 70mb) loaded into a byte array. My quesion is, since I'm not actively modifying the byte array, can I impliment a form of multithreading where all 3 threads read the same byte array at the same time?

I have 3 similar functions, that only change based on numeric type:
<Extension()> _ Public Function ToNullableShort(ByVal str As String) As Short? Dim intReturn As Short
[Code].....
I was trying to make a generic function out of this, but couldn't do it. How can I make a generic function that will take a specific T and make it a Nullable(of T)?
I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
I'm using Visual Studio 2010 and automating Outlook 2007. I am writing a program that executes on incoming mail (which I have that working), but I want this program to inspect the subject line for a 5 character string that will be in the format of AB123 (can be any 2 letters followed by any 3 numbers). What is the best method to accomplish that?
I am having some trouble with creating a simple function that converts a column of a datatable to an array (containing all numbers). Upon running it, it says "Index was outside the bounds of the array"; however, I couldn't understand why my function would create this problem.Also since I do not usually program using VB.Net, I am not sure if my function has other errors (like syntax errors).
i'm trying to make a program that searches for a specific file in a specific file, so when the program loads it "writes" in checked list box the names of the drives installed to the computer, but what i want to do is: when the user checks the box, i want it to search for the file in that drive, but i don't know how to do it...
I'm using:
Imports System.IO Imports System.Collections.ObjectModel Public Class Form1
[Code].....
how to make it search in the other drives using the checked listbox?
Is there any class or specific method for getting non-primitive types in an assembly? FieldInfo.Gettype() will do for primtive types but what about non-primitive types?
I have a situation in which I must execute a dynamically built stored procedure against tables that may, or may not be in the database. The data retrieved is then shunted to a VB.Net backed ASP based report page. By design, if the tables are not present in the database, the relevant data is automatically hidden on the report page. Currently, I'm doing this by checking for the inevitable error, and hiding the div in the catch block. A bit kludgy, but it worked.I can't include the VB code-behind, but the relevant stored procedure is included below.However, a problem with this method was recently brought to my attention when, for no apparent reason, the div was being hidden even though the proper data was available. As it turned out, the user trying to select the table in the dynamic SQL call didn't have the proper select permissions, an easy enough fix once I could track it down.First and foremost - is there a better way to check for a missing table than through catching the error in the VB.Net codebehind? All things considered, I'd rather save the error checking for an actual error. Secondly, is there a preferred method to squirrel out a particular OLE DB error out of the general object caught by the try->catch block other than just checking the actual stack trace string?
SQL Query - The main gist of the code is that, due to the design of the database, I have to determine the name of the actual table being targeted manually. The database records jobs in a single table, but each job also gets its own table for processing data on the items processed in that job, and it's data from those tables I have to retrieve. Absolutely nothing I can do about this setup, unfortunately. [code]
I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
