View 13 RepliesI am doing a simple database project.I need to give the input in the database which is an access db from my input form and i have managed to do this part right.then i need to retrieve the details from the db using multiple search fields and show them in the datagrid view.I have 8 search fields(5 textboxes and 3 combo boxes). I also have included 4 other buttons which respectively clears the search boxes;clear the results of the gridview; show all results from the database;go to the input form and offcourse 1 search button.now all the buttons working fine except the search button. actually when i click on the search button if i include sql query for all the search fields only the first one works and also if i have clicked any other buttons before clicking the search button nothing happens, no result is shown and it happens the same if i search once and clicked any other buttons and come back to search, no result. I need to show the results in the gridview depending on the user input on those search criterias. user should be able to search in any combinations.I am using the below codings in my search form. the combo boxes are not bound.datagrid is bound to database though.

I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.

Ok so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.
I know that it needs to be in a loop and its needs to Parse the wepage(Dim web1 As String = Me.WebBrowser1.Document.Body.InnerText)
The criteria is: Starts with 1 to 4(random) integers, Followed by "my" then 13(random) numbers and letters. Or if it starts with "167my" + 6(random) number and letters.
Edit: Also im going to try to make it loop through a list of webpages to do this.

I've got a form that populates a DataGridView from an excel file. How would I filter that DataGridView so only the search criteria are visible. I need to search through 2 columns by all rows. I'm not very good with datasources I guess and can't figure out what all I need to accomplish this. DataSets, DataViews, DataTables.

View 4 RepliesOn my view there is a datatable holding a collection of ServerRow and 4 textboxes (Hostname, OS, Location, Zone). When the user types into any of the 4 boxes I want to immediately filter this list. I have this code setup and ready to go that on the set method of each textbox property I call the filter method.
Now onto the problem: if I have 4 criteria that means I have 2 to the power of 4 different scenarios. What I would like to do is write a linq statement with all of these scenarios dealt with such that if any of the properties are NullOrEmpty they will not be used in the Where clause and on the flip side if there is a value the corresponding field will be searched with a Contains.
Example
AvailableCis = New ObservableCollection(Of ServerRow)
(_CiData.Where(Function(ci) ci.OS.ToUpper
.Equals(_selectedOS.ToUpper) AndAlso
ci.HostName.ToUpper.Contains(_ciNameFilterText.ToUpper))
.OrderBy(Function(a) a.CiName))
This example shows how it works with 2 criteria and both of those criteria are set.
how can i get the illegal character in a string

I have finished my database using Dreamweaver ASP VBScript and Access, the only thing left is to create the searching system. My search form works fine when posting just one filed. The results page Recordset goes as follows.
Code:
I need 7 different fields on my search form, this what I did but it doesn't work.
Parameters:
Name: MMColParam
Type: Text
Value: Request.Form("Ref")
Default value: 1
Name: MMColParam
Type: Text
Value: Request.Form("New_resale")
Default value: 1
"Price" is a special one because this is a list menu with different amounts, like 50.000, 70.000, 90.000, and so one. The idea is to make this list menu post to the result page, only to display records under or equal to the given value. less or equal > than 50.000 or 70.000, etc.
I am working on a utility to reformat a text file. Working on language to remove duplicate record entries. However there are desirable ("keeper") duplicates and then those I want to remove. I handled the problem by temporarily assigning a unique number to each @D line, then stripping them off after I've removed duplicates. So far so good, except in removing unwanted duplicates I have an extra of the "keeper" duplicates left that doesn't get removed. See below. I am wondering if there is a way to search for a line in a textbox starting with a certain character, but is also proceeded by 2 blank lines and followed by 1 blank line. CODE IM USING TO REMOVE DUPS yet keep formatting with blank line separators, etc.:

I would like to query an Employee by matching First and Last name. Ideally, I'd like to be able to specify that in one EmployeeQueryRq QBFC object.
I think I have a start:
Dim EmployeeQueryRq As IEmployeeQuery
EmployeeQueryRq = requestMsgSet.AppendEmployeeQueryRq()
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.MatchCriterion.SetValue(ENMatchCriterion.mcContains)
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.Name.SetValue(LastName)
Is there any way I can add an additional NameFilter to the same request? Or am I stuck walking a response list for the other criteria (albeit a smaller one limited to containing at least one value)?

What might be wrong in here?I set it all to string, is the primary key usernum not a string.
changing the way the site search is done from just search a phrase as one string to searching a phrase "as multiple words" search. For example, if I search "cute puppy" right now, it will search it for "cute puppy" as phrase and won't match just "cute" and "puppy". The way the search is implemented is by passing a search phrase to a Stored Procedure in SQL Server.So now, I need to change to site search so when "cute puppy" is searched, it will search two words.... "cute" and "puppy" instead of just "cute puppy". Below is how the store procedure is implemented
