I guess I just cant seem understand this correctly
Dim StatusClosed As String = Form11.Closed_Code.Text ' usually = S or ClosedSale or Closed Sale
Dim SubjId As String = Form10.add_Num_txt.Text ' usually = StreetName or Street Name or SN[code]....
If SubjId is StreetNumber or SN its ok , if its Street Number with the space I get error
If I place a ' around {3} in my afilter line then it works if the SubjId is Street Number but not StreetNumber or SN
Can someone take a look at my "afilter".I am getting an error when I try to read a file.Syntax error: Missing operand after 'Number' operator it works with some files but others perhaps I dont have it written correctly. [code]
First I tried getting a SQL query into an array, and then mail it. Made the data incomprehendable. So someone told me to use CSS to build a table format, filling it with the array. A LOT of hard work (since I had to learn css all the way from "what is a css".
Then I was told "Array? why use array when DATATABLES are soooo much easier"
So here we go again. "What is a datatable, and how does it work"
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?
I would like to know how to filter out system tables and only return user tables .when i run the code it displays lists of system tables with user tables list in combobox.I have just gotten into vb.net and have tried few ways to do this but dont understand well enough.
So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.
I am trying to build a filter string for my DataView, but I have run into a problem. My underlying DataTable contains values that are formatted when displayed in my DataGridView.For example, if the DataColumn contains 1.52 and the DataGridViewColumn.DefaultCellStyle.Format = "n0" then 2 is displayed.So the user sees 2, then sets the DataView.RowFilter = "DataColumn = 2", and no DataRows are returned. Is there a way to format the DataColumn in the RowFilter string? For example, DataView.RowFilter = "FORMAT(DataColumn, "n0") IN (2, 4)". This filter string should return 3 rows. If not, can LINQ do this?
I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.
I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
I have a dataset filled with content from a XML file:[code]Now I want to have the most recent date of each asset written to a SQL database. At this moment i write al the records in the database, where I sort the dataset on Date, so the asset with the most current date is writeen to the database. Is it possible to do a 'filter' of the data first before writing to the database?I can use Max(date) is SQL to filter the correct records, but I want to do it right from the start.
When I use a command such as: Me .TableAdapter.Fill(Me.SomeDataSet.Table)
I am going out to the database, gathering the requested information and filling the dataset. Therefore, everytime I add a query to a table adapter, it is also going to the database to get the information. So, my question is, how do I fill a table in a data set with all the records in the database table and then, filter the information I've already collected in the dataset without going back out to the database again?
I have mp3 database (access). I want to filter table and show 100 most played songs. There is a field "PlayCount" which is increased every time the song is played. I know how to use TOP clause, but there is a problem when I want to sort results in descending order by "PlayCount" .here is the sql query: SELECT TOP 100 * FROM Database ORDER BY PlayCount DESC this query returns 120 results. If I use "TOP 200" it will return 278 results. But everything works fine if I use ORDER BY Filename.
What code I need to search a whole table (not just one column). I can already search a column but how do I search the whole table for a string . source1.DataSource = ds.Tables(listboxselect) Grid.DataSource = source1 source1.Filter = "id = " & searchtxt.Text
I am very new to vb.net, just wonder can I use vb.net to do something like this : I have alphabet from [A][B]...to [z]. When A is clicked, product name that start with "A" and it's price will shown in a table below.

I am a newbee in vb.net 2008 i am making a simple inventory system.now my problem is i want to get the filter earliest date in my data table and put it to a textbox..
ex. Product Name Expiration Date Paracetamol 06/01/2011 amoxicillin 08/12/2011 Mefinamic 12/1/2011
I want to filter the earliest date "06/01/2011" and put it to textbox.
I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.
I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
I'm trying to create a print function with a corresponding print preview. For some reason, any string I create with String.Format will NOT show up on the print preview! Use the code snippet below as an example:
Dim strTemp As String strTemp = String.Format("{0, 210} {1, 75} {2, 51} {3, 200} ", "NAME", "PRICE", "QUANTITY", "DESCRIPTION")
rs2.Fields("Field29").Value has values like "YYYYMMDD" in a string.how can i convert a "YYYYMMDD" string to a needed date format like 'dd mmm yy' (or any format)
I have no idea why my OpenFileDialog Filter String is NOT working as expected?
Code:
All Picture Files |(*.gif;*.jpg;*.jpeg;*.jpe;*.jfif;*.png;*.bmp;*.dib;*.wmf;*.art;*.ico)|All Files (*.*)|*.* Well, when running my application and show OpenFileDialog it will filter and show *.bmp and *.jpg files, but it won't show any of *.gif or *.ico files!
In the Expression builder window in SQL Server Reporting Services 2008 R2 under Common Functions -> Text -> Item, there is an expression called Filter.This appears to correspond with the Strings.Filter method in the .NET framework. The description of Filter is as follows: Returns a zero-based array containing a subset of a String array based on specified filter criteria.The Example is as follows:
The example and description imply that you can inspect a multi-value parameter to see if at least one of the selected values is equal to the Match parameter. I haven't been able to get this to return anything other than #Error which implies the multi-value parameter is not a one-dimensional array. Parameters!MultivalueParameter.Value.GetType().ToString() returns System. Object[].
how to get this to work? I'm using the following work around to check if values were selected in the multi-value parameter:
This gets every C[blabla] value out of that string and when I ask for group(1), I don't even have to cut of the "C[" at the start and the "]" at the end.Now I want to do this but instead of using the C[] placeholder, I'm using G[] and so not a "C3" like string in that placeholder, but a guid so I get these:
When I check the regex, it matches a guid perfectly, but I don't get any matches when I use more than just one guid (or when I add characters before or after).I left out the "^$" so it doesn't define a start and end anymore, but that didn't seem to be the problem.
