I'm trying to get the first row in each worksheet to be shaded and have the font bold. Right now, I am able to get the first worksheet changes made, but none of the other worksheets within the same workbook are being changed. Here is what I have written so far for creating the spreadsheet and applying a format.Public Function WRITE_TO_EXCEL(ByVal dt As System.Data.DataTable, ByVal includeheader As Boolean, ByVal worksheet_index As Integer) As Integer
So i am trying to add new worksheets to excel...not a problem there, but then I had a thought: What I really need is the proper code to add new worksheets on open that are named all of the dates in the current month minus saturday and sunday dates. That is what started to throw me for a loop. so i started with
set newsheet = worksheets.add newsheet.name = date $
Is it possible to manipulate data in worksheets?[code]...
what i want to do is round off the time in if the time is greater than 6:00 example please look at the data date 8/2 and 8/3. i would like to modify it and make the 6:01 to 6:15, and 6:16 to 6:30 , every 1-15min late the time would round off to the nearest 15mins.. my question is how can i make loop in the column "time in" and every time the program sees a "late IN" it will round it up to the nearest 15mins.
I have a bunch of Excel workbooks that contain multiple worksheets. I want to loop through each workbook and export each worksheet into it's own new workbook. I want one worksheet in each new workbook.
Here's what I've got so far: Sub ExportWorksheet(ByVal worksheet As Excel.Worksheet, ByVal filePath As String) Dim xlApp As Excel.Application = New Excel.ApplicationClass Dim xlWorkBook As Excel.Workbook = xlApp.Workbooks.Add worksheet.Select() worksheet.Copy() [Code] .....
I'm trying to delete all the worksheets contained in a workbook using the code below but I get this error:
"Attempting to call into managed code without transitioning out first. Do not attempt to run managed code inside low-level native extensibility points, such as the vectored exception handler, since doing so can cause corruption and data loss."
For Each obj In xlWorkBook.Worksheets xlWorkBook.Worksheets(obj.Name).delete() Next
I tried to do this a different way yesterday and it told me I couldn't have a workbook with no worksheets. Is this written in stone or can it be done?
In VB 2008, I am trying to create an app that will copy a range of cells from one worksheet ("xlWS1") in the first workbook ("xlWB1") to another worksheet ("2") in a second workbook ("xlWB2"), starting in cell A1. I would like this to be activated by a button.Then, another button will copy the same cells from "xlWS1" to "xlWB2", worksheet "3", and so on for each subsequent button.
xlWB1/xlWS1 contains data in the cells that is updated from our data acquisition system once per second. (we perform jet engine testing). "xlWB2" sheets (6 of them) will contain the saved data from the "live" screen (xlWS1, came cell range) in the first WB. There are several different versions (filenames) of the second workbook, one for each engine model.Both workbooks should already be open, but I would also like the app to open them if they are not open already.
We have been using VBA macros to do this, but run into problems when someone saves the second (destination) workbook under a different filename. For some reason, if the filename of the Wb that is already open isn't the same as what's in the macro for that button, the macro's defined workbook is renamed in the macro. I am trying to get away from using the macros to keep this from happening, and to make an app that's "foolproof" so it is more reliable.
I already have an app that will open the proper workbooks. I may combine the two apps in the future. I can't find a solution for this. The VBA code is quite different and simple as far as opening, activating, copying, etc. Basically, I can't seem to find any self-explanatory "activate/copy/paste, etc." namespace in Vb 2008 like I used in the VBA macros.
I'm sure the solution is simple, but I just can't seem to find it in the MSDN library or the VS 2008 book I have. Everything in the book talks about accessing databases, which we don't use (yet). There's nothing concerning this issue with Excel 2003 workbooks/worksheets.
I'm trying to generate Office 2010 files (xlsx) in a vb.net project (Visual Studio 2010 fw 4.0).On my developing PC it works. Once on the server it generates an error:Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).On the server I tried with dcomcnfg and navigate to DCOM Config and locate Excel. To solve the problem I would have chosen Customize in the Security tab under Launch and Activation Permissions and add the account under which the site is running (our server task user) and assign Local Launch & Local Activation permissions.[code]
I want to write an Excel macro to set print formats in all worksheets in a workbook. I don't think you can do this by grouping; it appears you have to do it in each individual worksheet. I want to be able to run a macro in any workbook to loop through all worksheets in the workbook and then select the first worksheet.
How do you have the macro determine how many worksheets there are and set the loop counter equal to that number?
I've created a two-worksheet template in Excel - the first sheet is for pretty charts, and the other sheet is for the data that drives those charts. I've written a vb.net 2005 app that can dump in all my data on the second worksheet, and the chart worksheet updates perfectly.I would like to do this report several times over in the same workbook. (So the tabs would read 'Person1 - Chart', 'Person1 - Data', 'Person2 - Chart', 'Person2 - Data', etc.)
My solution was to, for every person this report was going to be run for, copy the chart template, and then copy the data template. The problem is that every chart template that is created points to the original data worksheet. How can I set what worksheet each chart worksheet is pointing at?
I have been looking for a good Example of Code to Compare 2 worksheets in the Same work book I have not had much luck. The Goal when complete is to compare Sheet 1 to Sheet 2 Then the Difference Recorded on Sheet 3 as a complete row with a date Stamp in A . If it is just a change then it is color coated Orange. If total new entry that was not on the sheet then it would be green If a Row is deleted in would be Pink.
I'm allowing users to change data in a DGV. Is there some kind of built in method for DGVs that updates the table with the new values in my Access database? I have a save button that performs the following:
I have 2 workbooks( Book1 and Book2) with multiple sheets.I am only interested in one of the worksheets in the workbooks(both the worksheets names are the same).The thing is that the data is in the form of pivot tables, so each time i have to filter according to specific categories, copy and paste into another new workbook.The thing is column headings in both the worksheets are different,BUT BOTH the worksheets data must be combined into 1 single worksheet( row after row).
Meaning in Book1, my columns are in the form of Cost, revenue,margin and in book2, the columns are in the form of Cost,Revenue, Profit Margin %.... That means i must add a profit margin % column in Book1 and a Margin column in Book2 before I combine the data into a single worksheet. Each week, new data gets added into Book1 and Book2, so I wish to automate this by creating a code, so that when the source data changes, my new workbook's data also changes.
I've got 1 form, with a TextBox1, where I want the news to pop-up.Now, I've made a kind of admin menu, where there's another TextBox in another form, and I want it in such a way, that when I press the "Accept" button, the text saves itself and shows up in TextBox1.[code]Can I control form 1, with form 2?
In my form load event I am setting the defaultcellstyle formats. They are not taking hold anyone know why? None of the formatting that is expected in the code after I bind the datatable to the grid is getting done even though the code steps through it
Private Sub frmADRORD_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'wire the delegate function for incoming updates AddHandler m_helper.DataUpdate, AddressOf UpdateGridInvoker 'bind the visual grid with the binding source
I have add,update,delete buttons on my form.A message box should appear on the screen "should have values to Add/delete/update/" if user clicks on Add/delete/update buttons without having any values in the textfiled,i have around 20 text fields on my form.
The general purpose of my application simply reads a line of text for example:
1. I have a printer issue 2. I have a software issue
I have a rule set as follows:
'Define the class 'Printer' with 14 values as a string... Dim Printer(13) As String 'The string 'Printer' gets assigned a value, this is repeated another 13 times... Printer(0) = "Printing"
[code]....
The code simply uses a number of keywords to detect if the issue is a 'printer', 'software', 'telephone',. or 'password' problem.I want to apply this rule set to 10 issues within the same rich text box, with the results sent to a text file. The exporting to a text file I can do, however the main issue is, i cannot read the lines individually.
I tried applying an animation to an object in powerpoint through VB.NET. I'm only a beginner and have tried my best to figure it out with something like the following code which is two objects using one as the trigger. I managed to get it working in pptVBA but just can't get it to work in .NET. I keep getting an error COMException was unhandled.

I have a dialog with an OK, Apply and Cancel button. I want the apply button to have the same effect as the OK button, but the dialog should not close. Can you stop the dialog from closing when you set a dialog result value (as I want to when clicking the Apply button)? Basically I have some settings that are passed into the constructor of the dialog. The dialog then updates its controls with these settings. At the moment any settings that are changed in the dialog are applied when the dialog closes via the OK dialog result (i.e. the code that calls the dialog also applies the changes). This is the way I would prefer it to happen, but the only way I can think of to get what I want to work is to apply the settings changes before I set the dialog result value (i.e. in the dialog code). This essentially makes dialogresult useless in my case as I cant use it to get the effect I am after.
I have an application that is writing a comma separated values file. How would I go about altering the permissions of that file from .NET - for example to give read-only permissions to a particular active directory group?
I have a DataGridView that loads info from an Access DB. The user can change the data accordingly, but how can I make it so the form will save the data that was changed? I know I'll have a SAVE button... but not sure what methods to be calling on the DataGrid
I'm trying to set ACL's on a folder using Directory.SetAccessControl. More specifically, I want to grant "Users" full control on a folder. AddFileSecurity works perfectly. AddFolderSecurity does not. It's result is that "Users" will get added to the folder's ACL but "Full Control" is not checked off (nor are any other permissions).
I'm creating a windows application form in vs 2005 for a client.. It's a data-tracking application. I have a few questions.The client wants a logon screen to be added into the application (at least any way or method that'll ensure that security was applied). My question in regards to this topic would be; Is it necessary to create a logon screen (or even a user authorization) for a windows form? I realize that in a webform project, security should always be considered and should be applied in all areas. Although with a windows form, I thought you can authorize who can gain access to the application by defining which workstations to install the final production release of the application (when its time to deploy the file). Is this correct?
My next question is, what is the best method to exporting data from EXCEL to SQL tables? I have many Excel files that I'd like to take portions of data from each file and insert them to there proper table.
The last question is about deploying a windows form application. As you can tell, I don't have much experience when it comes to developing Windows Form projects. Anyways back to the topic, When deploying a project, does it provide a .EXE file (installation package) to install the application on the workstation? Or is it a .EXE file of the application, where you can run it and no need to install anything?
I am working on applying date validation to excel cell(range) from VB.NET.
Private Sub DateValidExcelRule(ByVal worksheet As SpreadsheetGear.IWorksheet, ByVal DateRange As String) Dim dt As Date = CDate("1/1/1900")
[Code].....
When I enter 4 digits whole number 7777 it is validating correctly showing message Enter Valid Date, but when I enter 5 digits 77777 it is accepting the value and converting it to 12/10/2112 value and not showing any error message.
Here all I want to do is I want to validate the cell value to any date format mm/dd/yyyy.
I created a form with a datagrid to show data stored in an Access database. It shows the data correctly, using the code:
[code]...
("compras" is the table name and "Comprasver" is the dataset name).The form also has 3 textboxes and 1 DateTimePicker.Then I created a sql query to allow the user to search within 4 fields of the table (field1, field2 and field4 get the data in the textboxes and field3 gets it in the DateTimePicker). The query looks like this: SELECT field1, field2, field3, field4, field5 FROM compras where field1 like "%"+?+"%" and field2 like "%"+?+"%" and field3 like "%"+?+"%" and field5 like "%"+?+"%" field4 is not an important search criteria, so I didn't include it in the query. Field1 and field2 are both string type. Field3 is a Date type and field4 is integer.Once I made the query, it automatically added a toolstrip with a code, which I cut and pasted in my "Search" button "click" event. The code looks like this:
[code]...
But every time I try to search, no matter which criterias I fill in (even if I fill in none of them), I get an error message saying something like the conversion of the "" string into Integer is not valid (my Visual Studio version is in Spanish, so I don't know how to exactly translate the error message).It's supposed to let the user fill in one, more or all search criterias (all 4 search fields).I found out that if I delete from the query the two fields that don't have String type data, it works correctly. What should I do in order to be able to use the Date and Integer type fields as search criterias too?
Okay in my program I have users select options and then it writes text to a file. When the user restarts the program, I want it to read from the file and search for specific text like "User is a senior,False." At this point if the file has this text, I would like the program to read from a line in the program.
