Forms :: Integer Value Changing When Compare Cell Data By Using 'IndexOf' Feature?
Sep 17, 2010I have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.
Here is my code
strOriginal = dtbExcelData.Rows(0).Item(0).ToString
y = strOriginal.IndexOf("@")
strA = strOriginal.Substring(0, y - 1)
[code]....
For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.

Prevent Moving From A Cell In Datagridview That Has No Data?

Make DataGridView TextBox Cell A ComboBox Cell When It Has Focus
Dec 23, 2011I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

View 5 RepliesRegex To Extract Cell References From Excel Formula To ArrayList?
Jan 5, 2009Has anyone created a regex that matches each of the cell references in a given Excel formula? I'm trying to extract a list of cell references into an ArrayList from a provided Excel formula. Ideally, the ArrayList would also preserve any cross-tab or cross-workbook reference information. The key is for the regex to be compatible with any potential Excel formula, as the formula will change with each use.This seems to capture cross-workbook references:

VBA In Excel - Tag 24 Integer Variables And Put Them All Together In One Cell
Jul 1, 2009[Code].....
I am writing a VBA code for testing different combination of 24 variables and recording a result which corresponds to each combination of 24 variables. so I have an equation with 24 variables and one result. In excel I have one column which contains the 24 variables and the column next to it contains a figure which shows the result. what I need to do is to write loops to change the 24 variables between 1,2, and 3 and then record the result of the equation for each combination of 24 variables. I have written the loops (24 loops) and can record the result for each combination, what I have to do at this stage is to record the combinations which relates to each result.
As there is only one result for each combination of 24 variables I was wondering whether I can tag each variable (in each cell) in a way that in the final sheet in the cell next to the result cell I can write for example 111123123111233311121232. This means that after each loop I am taking the values for each variable in 24 cells and put them all together in one cell in the final sheet. These variables are changing in each loop, the label should change as well after each loop so after the completion of the code I can find out which combination relates to which result. I have tried to define an array or matrix but I couldn't fix the problem. This is the input sheet (the code changes the values in the cells in A column after each operation)

This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

DataGridView Image Cell Losses Resolution If Cell Size Is Smaller Than The Image Size?
Apr 30, 2012I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
