DatadGrid - Merging Two DataSets From Different Servers
Sep 22, 2009
I am trying to merge 2 datasets from 2 different servers, SQl 2005. I need to take 2 fields from one table and five from another to create one merged dataset and bind it to a datagrid, in an 2008 ASP.net application. The first table I will be saving to is empty just the table schema is there, The second table that the datagrid is populated by, has two columns containing dropdown box and a text field for user to edit these fields, these will be saved into the first table along with the user information, and a time stamp, but when a user pulls this information again the changes in the datagrid will reflect these changes.
I have two datasets called ds and ds1 that I want to merge into a grid. I get data from the first dataset to display in the grid but the second dataset where I want to display a count I don't get any data from it. I am trying a ds.Merge(ds1). here is the code i have for the sub. What am I doing incorrectly?
I have two databases. One is an SQL database and the other is an Access database.
In the Access database, I have a table with three columns EMPID, FIRSTNAME and LASTNAME.
I load this in my VB program to a table called "EMPID_Table"
In the SQL database, there is a table that has a lot of data that I need to retrieve based on the Employee#, which is the same as the EMPID from the Access database. In my VB program this is loaded into a table called "WagesTable"
How can I merge these tables, or add the columns FIRSTNAME and LASTNAME to the WagesTable
to the correct Employee# in my VB program? I cannot change the SQL database at all, I can only read from it.
Access Query:
Dim EMPID_Query As String = _ "SELECT *" & "FROM [EMPID_Table]" 'This returns EMPID, FIRSTNAME and LASTNAME 'I fill this to a table called "EMPID_Table"
In a nut shell what I am trying to do is, pull one or more tables into a datagrid view. I am having one heck of a time returning multiple datasets. I can eleect all indavidually, but when I try to select more than one, I only get the last "table" in the list. If I could establish a ODBC connection that would be better, but this will have to work for now with some canned queries I have.
I don't really know how to code but am pretty good at tweaking. I'm trying to set up a script that I can run to delete a single file, multiple files, a folder or multiple folders on a list of servers.I was thinking that the script could read the files to be deleted from a .txt file and apply the deletion to a list of servers in another .txt file.Example:
FilesToBeDeleted.txt: \(insert_server_name_from_list)c$Program FilesBINexample_file.rpt or
i want to make a program merge 2 .png images, like the layers in Photoshop, if you know what i mean.. cause i want to create a sprite generator in RMVX.
In .net MDI application the menu of child form automatically is merged to the menu of parent form.Is there a way to do similar thing with the tool bars.The concept is to send the toolbar of active child to the parent toolbar stripe
I wrote an application which converts .doc files into .pdf. Now I would like to add one more thing: before converting the .doc file, which is selected by the user, I would like to add the content of an other (default) .doc file, which will not be selected by the user but the directory where the file is will be already in the code, in front of the file selected by the user. So after the two files are merged I will have the merged file converted to PDF.
I have a Main Table that contains all the distinct values in a DataTable.DataColumn. also have a Child Table that contains distinct values created by the user.I want to merge the Child Table DataRows that match on the Value column with theMain Table DataRows to create the New Table (shown below).I want to preserve the values in the Selected column of the Child Table.Here is my problem, if I use the DataTable.Merge method the DataRow that contains "888" in the Child Table is added to the New Table, but it doesn't contain a RowState = Added, thus I can't filter for added rows to remove them.
I'm using the details on connecting to a server from a client here: [URL]
It's quite out dated but I just need it for a quick project. I need the client to auto-connect. This program will be running on the LAN only, is there a way to find on what computer the server is running on (i.e. all computers hosting the specific server on port x). I've seen it on a couple of games that run on LAN. Without access to the internet, they manage to display all available games on the local LAN. I'm doing this with VB.net.
I am using the following code to get the Disk I/O on various servers. For now I am just retrieving the DiskReadsPerSec to get a feel for it. The return data gives a uint32 for each drive on the server and a total. My questions is what is the time frame that this represents? Is this at the second that my code polls the drive or is this over the last few seconds or do I need to do multiple runs to get an average.
My intention is to build a graph for each drive so I wonder how often I need to poll the drive to get a acurate value.

I have two folders at different locations but with the same name. A file is generated in one of the folders and it is to be copied to the other folder but without overwriting the existing contents in C#.File.Copy overwrites the contents which makes me lose the previous contents. Is it possible to merge the contents in the folder?
I have a PDF template with 1 field on it: Barcode I have a CSV with about 800 records all containing 1 field; Barcode I know how to open de Template and assign a value to a field. And how to write a new PDF with the right barcode on it.But my problem is that I want to create 1 PDF with 800 pages.Thus, not 800 seperate PDFï and then merge them into 1 but I would like to write the content of the memory stream into 1 pdf.
I have datagridview and it have 10 columns and 1 row. Here i all the cell values are sameSo I need to merge all cells and the value display in first columns. (Horizandal merging)
I have 2 DataTables in vb.net. Each is populated from it's own stored procedure. Table A contains a project number in the first column. Table B also contains the project number in the first column. Table A could have many records that have the same project number, but Table B will always have just one record in it per project number. I would like to append the data from Table B to every matching record in Table A. How would I do this?
in that for every selection of a single file in the list-box the content in the file is readed and written to a new word created automatically and saved to the same location.i cant able to move all the items for read and write operation.[code]
I have an access 2007 Database where I store several different "Jobs" such as repair job, data recovery job etc.
At the min I have a form where the user can view a customer's related jobs either by type, or all jobs related to the customer. I'm trying to do this by adding each job type to it's own DataTable, then merging the DataTables into one.
Private Sub rdoShowAllJobs_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoShowAllJobs.CheckedChanged '####################### Procedure Level Constants and Variables ########################### ' Dim dtDataRecoveryJobs As New DataTable
[Code]....
What I want is for the first column, ID, to contain the primary key from each table, but when the code runs it adds each primary key column from the tables to the end of the AllJobs DataTable! Am I trying to do something impossible here or is there a way around this?
1, Product A, NEW, 60 2, Product A, B, 60 3, Product A, C, 40 4, Product B, NEW, 30 5, Product B, C, 20
I want to write my procedure so that when I execute it, it will return a table as such.
Product Name, NEW, B, C Product A, 60, 60, 40 Product B, 30, 0, 20 SELECT PRODUCT,(CASE WHEN CONDITION LIKE 'NEW' THEN QTY END) AS NEW, (CASE WHEN CONDITION LIKE 'B' THEN QTY END) AS B, (CASE WHEN CONDITION LIKE 'C' THEN QTY END) AS C FROM TEST
I got to the point where it will show different quantities in corresponding column but I was unable to merge them into single row.
is it possible that when i retrieve info out from the database and fill it into the datagridview, if the 'ID' column have similar IDs, those of column 'ID' will be merge together?[code]
I have a program that takes some data from a Dictionary object, runs a batch process on it and then puts the output into a second Dictionary. The issue that I'm having is that the batch process can only handle 1000 records at a time and sometimes the list is larger than that. Right now, I'm looping through the Dictionary, taking records 1 to 1000 and putting them into a Dictionaryof the same type to process, running the batch, looping through the results to add them to the second Dictionaryand then starting the loops again at record 1001.
Is there a more efficient way to do this to pull out the first 1000 records into another Dictionaryand then batch insert the results into the output Dictionary? It seems like the kind of thing there'd be a function for, but I'm not sure how to do it.
i have a number of pitcures im merging together to make one picture.but the problem i have is the background color, the back color is black but i need it tobe white.
Dim Image1 As New Bitmap(PictureBox2.Image) Dim Image2 As New Bitmap(PictureBox3.Image) Dim Image3 As New Bitmap(PictureBox5.Image)
I lost the code to a program I made quite a while back so I was wondering if any one could help.I have a list box which has file locations loaded into it by the user..After they are loaded they click the merge button and it joins all the files loaded into the listbox into 1 exe..I have this code I upgraded from vb6. I think it is joining the files but only the first one in the list is opening when i run the new exe that is made when they are merged..[code]
I want to do several simple tasks. Doing each separately is easy but when I put them together I don't know what to do. For one thing to work all the code must be changed and everything else doesn't work. I want to:
1. Plot a graph of data from a DAQ. I can do this by using a Timer1_tick method and displaying the data on the linegraph as long as the timer is turned on. I've decided to stick with this method of acquisition. I want to acquire data for long periods of time (perhaps 3 hours) so a timer is pretty good. No problems here.
2. Apply a filter to remove noise from the plot dynamically as the data comes in so that I get a smooth curve instead of a jagged graph. I know I can do this with for loops if I'm using an array. But how do I do it since I'm using a timer? Here the problem begins.
3. Log every piece of the filtered data that the timer is getting to be exported to a CSV file. I learned how to do this with do loops but not with a timer or array. But I really need to use the timer this time.
4. Acquire statistics for the data like maximum value, minimum value, and average value dynamically as the data changes. I know how to do this with an array of data after all the data is acquired. But How do I do this with a timer while the data is still being collected?
5. Monitor the data coming in to execute an alarm (Or event, like stopping the acquisition) when the data coming in has plateaued and is constant (eg: The voltage I'm monitoring starts to become constant and becomes one constant value) - Ok I don't know anything about this.
6. Execute a mathematical operation on the data that has been acquired (post acquisition) like finding gradients and such. Basically this means "How do I now manipulate the data I have and where is this data stored?"
7. Know any good free linegraphs with autoscaling?
Here's my starting code that gathers data with a timer. How do I work from here?:
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing Timer1.Enabled = False
